Retrospective study of thyroid invasion and central lymph node metastasis in 124 patients with hypopharyngeal carcinoma

Objective: To investigate the characteristics of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma, and the impact on survival rate and quality of life. Methods: A retrospective analysis of 124 cases (122 males and 2 females with age range from 36 to 78 years old) with laryngopharyngeal squamous cell carcinoma who were initially treated in the Department of Head and Neck Surgery, Beijing Tongren Hospital Affiliated to Capital Medical University from January 2014 to December 2017 was performed. The clinical data included tumor location, pathological T stage, pathological N stage, invasion of thyroid gland, central lymph node metastasis, surgical procedures and so on. Patients were grouped according to if presence of thyroid invasion and central lymph node metastasis. With follow-up, the survival was analyzed by Kaplan-Meier method, and tumor recurrence and metastasis were evaluated. Results: Of the patients, 12 patients had thyroid involvement and 5 patients had central lymph node metastasis. The incidence of thyroid involvement was 8.16% (8/98) in pyriform sinus, 1/18 in posterior pharyngeal wall and 3/8 in posterior cricoid wall, with statistically significant difference (χ2=15.076,P=0.008). The incidence of central lymph node metastasis was 1.02% (1/98) in pyriform sinus, 3/18 in posterior pharyngeal wall and 1/8 in posterior cricoid wall, also with statistically significant difference (χ2=11.205, P=0.008). There was no statistical correlation between thyroid invasion or central lymph node metastasis and gender, smoking or alcohol exposure history and tumor pathological differentiation (all P>0.05). The 3-year overall survival rate was 80.65% and the 3-year recurrence free rate was 85.48%. Totally 24 patients died in 3 years, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. Local recurrence occurred in 18 patients, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. There was no significant difference in survival between patients with and without thyroid invasion and central lymph node metastasis (all P>0.05). There were significantly difference in 3-year overall survival and relapse-free survival among the groups with different T stages, N stages, pathological stages and tumor pathological differentiation levels (all P<0.05). There were significantly differences in the levels of serum calcium and FT3 between the groups with or without thyroid invasion and central lymph node metastasis (all P<0.05). Conclusion: The incidences of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma are rare, and the risk of occurrence is related to the primary site of tumor. Comprehensive evaluation, correct decision-making and accurate treatment could be helpful to cure radically the tumor, to prevent recurrence and to improve the quality of life of patients.

Frequency of Incidental Carcinoma in Thyroids Operated for Multinodular Goiter

Background: Multinodular goiter (MNG) is a common disease in Pakistan. However, malignancy can be found occasionally on histopathological examination of resected goiter specimens. The objective of this study was to determine the frequency of malignant lesions on histopathological examination in thyroid specimens operated for multinodular goiter.Material and Methods: A total of 154 patients undergoing thyroid surgery with preoperative diagnosis of multinodular goiter (MNG) at Al Nafees Medical College and Hospital Islamabad, Pakistan were included in this study. The preoperative diagnosis of MNG was made upon physical examination of thyroid and ultrasound (n=62 cases) and FNAC (n=43 cases) was done in selected cases. Gross examination was done and sections were taken from areas of thyroid with varied appearances including hemorrhagic, solid, firm, white, gray, gelatinous as well as necrotic areas. Qualitative variables, were calculated in terms of percentages and mean and standard deviation were used for quantitative variables.Results: Of the 154 patients with preoperative diagnosis of MNG, there were 139 (90%) female and only 15 (10%) male patients. The age range was 14-60 years with a mean age of 36 ± 10 years The incidence of thyroid carcinoma in patients operated for clinical diagnosis of MNG was 8% (n=12). Papillary thyroid carcinoma was the most frequent type of malignancy (83.3%; n=10). Multifocality (60%; n=6), bilaterality (33.3%; n=4) and left lobe involvement (80%; n=8) of thyroid were more common. Microcarcinoma (measuring 1cm or less) was found in 50% (n=5) of these PTC. Histological type of papillary carcinomas greater than 1 cm were follicular variant (n=3; 30%) and conventional (n=2; 20%) types. The maximum measurement of the tumor was 2 cm. In all cases of PTC, rest of the thyroid showed MNG on histopathology.Conclusions: Incidental finding of thyroid malignancy in clinically diagnosed cases of MNG is not unusual. Papillary carcinoma of thyroid is the most common incidental malignant finding in these cases. Multilocularity in thyroid is not an indicator of benign disease process.

\u201cThyroid nodular disease and PTEN mutation in a multicentre series of children with PTEN hamartoma tumor syndrome (PHTS)\u201d

PurposeTo report the incidence of 4–12% of differentiated thyroid cancer (DTC) and up to 50% of benign thyroid nodular disease and to describe nodular thyroid disease in a multicentre pediatric population with PTEN mutations. Methods: Retrospective data of pediatric patients with PTEN mutations collected from tertiary Departments of Pediatric Endocrinology of Turin, Milan and Genua, Italy, in the period 2010–2020.ResultsSeventeen children with PTEN mutations were recruited in the study. Thyroid involvement was present in 12/17 (70.6%) subjects, showing a multinodular struma in 6/17 (35.3%), nodules with benign ultrasound features in 5/17 (29.4%) and a follicular adenoma in 1/17 (6%). No correlation was found between thyroid disease and gender, puberty, vascular manifestations, delayed development, or brain MRI abnormalities, while multiple lipomas were associated with thyroid disease (p = 0.03), as was macrocephaly. Standard Deviation (SD) score head circumference was 4.35 ± 1.35 cm in subjects with thyroid disease, 3 ± 0.43 cm (p = 0.02) in the group without thyroid disease. Thyroid involvement was present in all subjects with mutations in exon 6 (4/4) and exon 8 (3/3) of the PTEN gene (p = 0.02).ConclusionIn the presented cohort, benign thyroid disorders were prevalent, with no evidence of DTC. A correlation was found between thyroid lesions and head circumference and the occurrence of multiple lipomas. Future studies in larger cohorts should assess whether risk stratification is needed when recommending surveillance strategies in children or young adolescents with PTEN hamartoma syndrome.

Intravascular Lymphoma in Patient With Celiac Disease With Multi Glandular Involvement

Case Presentation: The patient is a 60 year old male with a past medical history of celiac disease, paroxysmal Afib, iron deficiency, and CAD who presented with lightheadedness, dizziness, and fatigue. Notable workup revealed that the patient had Afib with RVR, a TSH of 0.189, Free t4 0.51an LDH of 2726, hemoglobin of 8.7, AST of 155, ALT of 19, WBC of 4.5, and serum iron of 20. The patient’s cardizem dose was adjusted and repeat transthoracic echocardiogram was unremarkable compared to history. The patient presented again with complaints of abdominal distension, postural dizziness, occasional night sweats, and fevers. Repeat workups revealed pancytopenia, proteinuria, hypotension, and anasarca most pronounced in the lower extremity and scrotum. Ultimately, a kidney biopsy revealed an intravascular B cell non-Hodgkin lymphoma (IVBCL). Notable repeat labs include a CRP of 44 and a failed ACTH stimulation test. A brain MRI revealed a 6mm pituitary microadenoma. The patient placed on an R-CHOP regiment and is scheduled for repeat MRI to rule out pituitary involvement. Discussion: IVBCL’s are a rare form of diffuse B cell lymphoma and remain a diagnostic challenge due to the variety of involved systems including skin, CNS, and endocrine. IVBCL is also known to not produce a mass or lymphadenopathy. Celiac disease is a known risk factor for non-Hodgkin’s lymphoma. A literature search reveals a few case reports with common themes of increased LDH and inflammatory markers, anemia, and hepatic and renal dysfunction. Postural hypotension can also be a presenting symptom due to IVBCL’s ability to infiltrate neurovascular tissue to cause autonomic neuropathy. However, in this case, the patient’s history of primary adrenal insufficiency makes this unlikely. Hypothyroidism secondary to pituitary and thyroid involvement was suspected due to TSH level suppressed enough for central hypothyroidism. Repeated MRI showed resolution of Pituitary Microadenoma post Chemo therapy.Sylvain Raoul Simeni Njonnou, Bruno Couturier, Yannick Gombeir, Sylvain Verbanck, France Devuyst, Georges El Hachem, Ivan Theate, Anne-Laure Trepant, Virginie De Wilde, Frédéric-Alain Vandergheynst, “Pituitary Gland and Neurological Involvement in a Case of Hemophagocytic Syndrome Revealing an Intravascular Large B-Cell Lymphoma”, Case Reports in Hematology, vol. 2019, 6 pages, 2019. https://doi.org/10.1155/2019/9625075Catassi C, Fabiani E, Corrao G, et al.

INFLUENCE OF BASIC AND EXTRACORPOREAL THERAPY ON THE LEVEL OF THYROID HORMONES AND ANTITHYROID ANTIBODIES IN PATIENTS WITH RHEUMATOID ARTHRITIS WITH THYROID INVOLVEMENT

Objective: to study the effect of treatment on the dynamics of antibodies to thyroid hormones in patients with rheumatoid arthritis with thyroid involvement. Methods: 27 people were selected with a diagnosis of rheumatoid arthritis, with a different cjndition of thyroid gland, tread with basic therapy (methotrexate or leflunomide). The patients were divided into three groups, depending on additional anti-inflammatory therapy: group 1 - NSAIDs, group 2 - NSAIDs and glucjcjrticoids (GC), group 3 - NSAIDs, GC and plasmapheresis (7, 15 and 5 patients, respectively). Concentrations of TSH, T3 and T4 were measured using ELISA, antibodies to T3 and T4 - by indirect ELISA using antigens immobilized on magnetic polyacrylamide beads. Marker levels were measured at admission to the hospital and at the time of discharge. Results. By the end of hospitalization of RA patients with autothyroid pathology in the hospital, there was a significant decrease in the content of antibodies in the blood to thyroid hormones. The level of antibodies to thyroid hormones in RA patients with concomitant autothyroid pathology demonstrated significant differences between the indicators before and after treatment in patients in the third group. The levels of antibodies to thyroid hormones in subgroup No. 3 after treatment significantly decreased by 75 % from the initial values. The other two subgroups also showed reductions in antibody levels, but these were not statistically significant. Conclusion. Thus, the basic therapy of RA, as well as additional methods of reducing RA activity using NSAIDs, GC, plasmapheresis, can affect the levels of thyroid hormones in patients with thyroid lesions. The most pronounced effect on the concentration of antibodies to thyroid hormones was found in patients who received a course of plasmapheresis in addition to other methods of treatment. T4 level after treatment was proportionally reduced in patients of all three groups, while remaining within the normal range. For T3, there were no distinct dynamics after treatment. The results obtained indicate a predominantly autoimmune genesis of thyroid lesions in RA.

Ultrasonic Characteristics of Medullary Thyroid Carcinoma: Differential From Papillary Thyroid Carcinoma and Benign Thyroid Nodule.

The aim of this study was to evaluate the differences in ultrasonic features of patients with medullary thyroid carcinoma (MTC), papillary thyroid carcinoma (PTC), and benign thyroid nodules. This study included 53 cases of MTC, 151 cases of PTC, and 200 cases of benign thyroid nodule which were pathologically confirmed. There were no significant differences in sex and thyroid gland involvement among the MTC, PTC, and benign thyroid nodule groups. The age among the 3 groups was statistically different (P = 0.002). The TNM stage of MTC was significantly higher than that of PTC (P < 0.001). Compared with PTC, the lesion size, shape, margin, echogenicity, internal nodule component, and blood flow were significantly different in MTC (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P = 0.045, P < 0.001). However, there were no differences in the form of calcification and cervical lymph node involvement between the 2 groups (P = 0.671, P = 0.128). Except for the lesion size and shape (P = 0.068, P = 0.444), MTC group have significant differences in the grade of Thyroid Imaging Reporting and Data System, lesion margin, echogenicity, internal nodule component, calcification, cervical lymph node, and blood flow compared with benign thyroid nodule group (P < 0.001, P = 0.014, P = 0.032, P < 0.001, P < 0.001, P < 0.001). Our data indicate that ultrasound have important value in preoperative diagnosis of MTC. The ultrasonic features of MTC include relatively large nodules, aspect ratio less than 1, smooth edge, solid hypoechoic, microcalcification, and rich blood flow. It is necessary to combine multiple ultrasonic features for the differential diagnosis of MTC, PTC, and benign thyroid nodules.

Significance of changes in general clinical analysis of blood and thyroid status in people with neoplasm of the thyroid gland

Background. One of the major challenges of modern medicine is prevention and early detection of diseases, especially malignant tumors, since the stage does influence the prognosis and treatment costs. Thyroid involvement is currently one of the leading endocrine disorders in terms of overall morbidity and prevalence in the world. Thyroid cancer is one of the localizations, which being timely detected and properly treated, has a favorable prognosis, when 20–30-year survival rate exceeds 90 %. Therefore, the search for simple, minimally invasive, but highly informative techniques for optimizing the algorithms for diagnosis, differential diagnosis and monitoring of this disease remains a priority.&#x0D; Purpose – to determine and substantiate the diagnostic value of comprehensive assessment of the thyroid status and full blood count values in patients with thyroid nodules.&#x0D; Materials and methods. The study involved 60 patients with thyroid nodules, which according to ultrasonography (US) of the thyroid were classified as TR-4 category of thyroid nodules, TIRADS scale (4–6 points, suspected malignant thyroid changes). The examination included the following: questionnaire, ultrasound examination with fine-needle aspiration puncture biopsy, cytological examination, counting the thyroid hormone concentration, full blood count. The study was carried out at the premises of State Institution “Dnipropetrovsk Medical Academy of the Ministry of Health of Ukraine”.&#x0D; Results. Assessment of thyroid status of patients with thyroid nodules showed a significant correlation between the severity of thyroid malignancy and TSH levels (according to Kruskal – Wallis test, H = 7.30, p &lt; 0.05), FT4 (H = 17.64, p &lt; 0.001) and FT3 (H = 12.41, p &lt; 0.01). Patients of Group I with benign thyroid process showed significant (p &lt; 0.05) decrease in total hemoglobin along with significantly frequent (p &lt; 0.05) microcytic anemia. According to the studies, Group II had a significant (p &lt; 0.05) decrease in total platelet count and plateletcrit, as well as an increased average platelet volume and the percentage of large platelets compared to Group I. The blood values in malignant thyroid process (Group III) are characterized by increased levels of leukocytes and the proportion of eosinophils and basophils in the leukocyte formula compared to Group II (p &lt; 0.05).&#x0D; Conclusions. The outcomes of comprehensive assessment of thyroid status and full blood count values in patients with thyroid nodules can be used in preoperative diagnosis as a differential prognostic tool to assess their malignant potential.

Disseminated cryptococcosis with gastric and thyroid involvement

This is a case of disseminated cryptococcosis with gastrointestinal and thyroid involvement. This case illustrates that gastrointestinal and thyroid involvement may be an under-recognized phenomenon. Suspicion should be high in an immunocompromised patient with odynophagia and a thyroid nodule and warrants further investigation by endoscopy and fine needle aspiration biopsy.

Unilateral Periorbital Oedema with Hypothyroidism and Multinodular Goiter

Thyroid associated ophthalmopathy is an autoimmune disorder which involves orbital and periorbital tissue. The immune-mediated inflammation of the orbital tissues can involve extraocular muscles, orbital connective tissue or orbital fat and periocular soft tissues. Bilateral involvement of thyroid associated orbitopathy is usually asymmetric, but unilateral thyroid associated orbitopathy has been less reported. Periorbital oedema as the only sign with hypothyroidism is uncommon and if present, it is more frequent bilaterally present and no cases are evidenced as unilateral. Pitting oedema in hypothyroidism is rare and can be due to increased capillary permeability, decreased adrenergic tone and increase in serotonin metabolism. Unilateral periorbital and eyelid oedema can associate with various clinical entities, multidisciplinary team is necessary to exclude the concomitant disease, so the patient can immediately be treated with proper therapy. We represent the case of unusually unilateral recurrent periorbital oedema in the period of time for 3 years with stabilized primary hypothyroidism and multinodular goitre.

Literature Review of an Adult Woman with Wilms' Tumor

Wilms' tumor (WT), also known as nephroblastoma, is considered as an embryonal tumor due to nephrogenesis and histologic mimics of the early-onset age. WT is the most common renal tumor in children, but it is extremely rare in adults. WT is known to be a very chemosensitive tumor, and modern clinical trials aim to improve risk classification to reduce the burden of treatment. Diagnosis of WT is usually made after nephrectomy, so the possibility of preoperative chemotherapy is only possible in patients diagnosed with biopsy. A 48-year-old female with a history of 3-week left upper quadrant and left flank pain applied to a general practitioner. There was no previous trauma, hematuria, or other systemic symptoms. Further investigation with computed tomography (CT) scan of the abdomen with intravenous contrast revealed enlarged left kidney mass lesion within the left lower pole measuring up to 7.4 cm × 7.5 cm × 9.2 cm [Figure 1]. The patient underwent open radical left nephrectomy, retroperitoneal lymph node dissection, and partial excision [Figure 2]. Radical nephrectomy was performed, and when nephroblastoma was detected in histopathological examination, she was consulted with medical oncology. After positron emission tomography-CT examination revealed a thyroid involvement, a biopsy was performed, and it was diagnosed as papillary thyroid carcinoma. Total thyroidectomy was performed by the ear, nose, and throat and papillary thyroid carcinoma was diagnosed. Then, the patient started on vincristine dactinomycin therapy. There was no recurrence at the 3rd, 6th, 12th, and 36th month controls of the patient.

Combination Surgical Procedure for Fourth Branchial Anomalies: Operative Technique and Outcomes.

Branchial apparatus anomalies of the fourth cleft are the rarest subtype of anomaly and occasionally present with suppurative thyroiditis or thyroid abscess due to their relationship with the thyroid gland. Surgical approaches vary and some surgeons favor cauterization of associated pyriform sinus tracts alone versus complete surgical excision. Currently, the literature is scarce and there is limited data on surgical outcomes and procedural steps. Here we describe a combination surgical technique for fourth branchial anomalies including: (1) surgical excision of the cyst and any external pit, (2) hemithyroidectomy, and (3) direct laryngoscopy with cauterization of pyriform apex tract, if present. A retrospective review was performed on all patients who underwent surgical excision of fourth branchial apparatus lesions (including fistulae, cysts, and sinus tracts) at an urban pediatric university hospital from 2000 to 2019. Data regarding demographics, medical history, surgical methods, complications, and surgical cure rates were collected. A total of 16 patients (9 female, 7 male) underwent a combination surgical procedure for fourth branchial apparatus lesions. Success rate after primary surgery was 94%. One patient had residual disease requiring re-operation. Two patients had post-operative complications: 1 transient vocal fold paresis and 1 seroma, both managed conservatively. A consensus surgical algorithm was created based on operative steps present in the majority of cases. A combination approach to fourth branchial apparatus lesions-including endoscopic cauterization, external excision, and hemithyroidectomy-is safe and provides a high rate of primary cure. Although less invasive options exist, remnants of the branchial lesion, especially in the thyroid, may remain and cause recurrent issues. Therefore, we advocate for complete surgical excision of this rare developmental anomaly, especially when obvious thyroid involvement exists.

Epstein-Barr Virus-Associated Langerhans Cell Histiocytosis of the Thyroid Gland

Thyroid gland involvement of Langerhans cell histiocytosis (LCH) is extremely rare in both systemic and isolated disease. The role of viral infection in LCH development is not yet fully understood. Although several viruses are proposed as etiologic factors, such as Epstein-Barr virus (EBV) and human herpesvirus 6 (HHV-6), they seem to play a bystander role in LCH. A 29-year old female patient with a prior history of multisystemic LCH (pituitary gland and skull bone), presented with a thyroid nodule. The patient underwent a total thyroidectomy and the histological examination revealed nodular lesions composed of sheets and clusters of histiocytes in the inflammatory background. The histiocytes stained positive for S-100 and CD1a and were negative for HHV-8, cytomegalovirus, and VE1 (anti-BRAFV600E) on immunohistochemistry. The EBER in situ hybridization for EBV showed frequent positive-stained cells. The conventional PCR analysis for EBV was positive and qPCR analysis confirmed a significant DNA copy number difference (p = 0.02) between the tumor and adjacent non-neoplastic thyroid tissue. PCR analysis for HHV-6, HPV, HSV was negative in both tumor and benign samples. In conclusion, the presented case showed a rare thyroid involvement by LCH associated with EBV infection, which has not been reported before. Further studies are required to investigate a possible etiologic link between EBV infection and LCH.

A Diagnostically Challinging Case of Primary Thyroid Kappa-restricted Plasma Cell- Rich Hematolymphoid Neoplasm with Focal Plasmablastic Differentiation

Abstract Introduction/Objective Most low-grade B-cell lymphomas of the thyroid are extranodal marginal cell lymphomas (MZL) and may exhibit focal plasma cell differentiation (PCD). PCD could occasionally be extensive, mimicking a true plasma cell neoplasm (PCN). PCN of the thyroid are extremely rare, representing either a component of plasma cell myeloma (PCM), or a primary thyroid extraosseous plasmacytoma (EOPC). We present a case of primary thyroid plasma cell (PC)-rich neoplasm with considerable diagnostic challenge. Methods A 46-year-old male underwent total thyroidectomy for hypothyroidism and compressive symptoms. Microscopically, sheets and nodules of PC with focal plasmablastic features were demonstrated in a background of fibrosing chronic thyroiditis. One benign perithyroidal lymph node was seen. The differential diagnosis included B-cell neoplasm with extensive PCD (ie, MZL or lymphoplasmacytic lymphoma) and PCN. Results Immunohistochemically, the PCs were positive for CD79a, MUM1, BCL2 and IgM with Kappa light-chain restriction and partial CD138 expression, and negative for CD20, PAX5, HHV8, Cyclin-D1, SOX11, CD117 and IgG. EBER was negative. Rare reactive-appearing B-cell aggregates with associated T-cells were noted. FISH for API/MALT1-fusion t(11;18) and PCR for MYD-88 mutation were negative. However, polysomy 18 (seen in 15–33% of B-cell lymphomas, including MZL) was detected. Serum proteins and PCM workup were negative. The findings were consistent with primary thyroid Kappa-restricted PC-rich neoplasm. While the absence of detectable B-cell neoplastic component was suggestive of EOPC, the diagnosis of MZL with extensive PCD was favored due to the thyroid involvement in a background of thyroiditis, absence of lymph node involvement, detection of polysomy 18, and absence of MYD-88. Follow-up of the patient was thought to be most reasonable. Conclusion Plasma cell-rich hematolymphoid neoplasms of the thyroid may cause a considerable diagnostic challenge. Differentiating between B-cell lymphomas with extensive PCD and PCN may be difficult or even impossible by morphology alone. Additional ancillary tests may be necessary.

MRI in Children With Pyriform Sinus Fistula

A variety of imaging modalities have been described for the diagnosis of congenital pyriform sinus fistula (CPSF). To date, there have been few MRI reports. To evaluate MRI findings of CPSF and interobserver reliability. Retrospective. In all, 115 patients aged 23 days to 15.4 years at operation. 3.0T/axial T1 -weighted image (T1 WI)-SPIR, axial T2 WI, axial T2 WI-STIR, coronal T2 WI-SPIR, diffusion-weighted imaging (DWI), axial and coronal gadolinium-enhanced T1 WI-SPIR. For each patient, the medical records, including demographics, clinical manifestations, and MRI findings were reviewed. All the MRI studies were interpreted by three radiologists independently. Kendall's W test was made to determine the interobserver reliability of three reviewers for MRI findings. CPSF occurred on the left side in 104 (90.4%) patients and on the right side in 11 (9.6%) patients. The male-to-female ratio was 59:56. The age at first episode varied from birth to 12.3 years. There was one neonate patient, who presented with a unilocular cystic mass in the left neck. A tunnel-like lesion between the pyriform fossa and the upper pole of the thyroid gland, T2 high signal behind the cricothyroid joint, thyroid gland involvement, deep neck abscesses or masses were noted in 46 (40%), 93 (80.9%), 96 (83.5%), and 36 (31.3%) patients, respectively. There was excellent interobserver reliability for all the MRI findings, ranging from 0.84 to 1.00. The sinus tract presenting with a tunnel-like lesion goes behind the cricothyroid joint in most cases. For patients presenting with acute suppurative thyroiditis (AST) or neck infection with thyroid gland involvement, the presence of T2 high signal behind the cricothyroid joint highly suggests the diagnosis of CPSF. MRI is a reliable method for the diagnosis of CPSF. 4 TECHNICAL EFFICACY STAGE: 2.

Is thyroid excision mandatory with laryngectomy in carcinoma larynx?

BackgroundAdvanced stage operable cancers of larynx are treated with total laryngectomy including thyroid resection in most of the cases, which may expose patient to hypothyroidism and hypoparathyroidism. The requirement of thyroidectomy during Total Laryngectomy is controversial.MethodsA cross sectional observational study was set out to review preoperative clinical and radiological assessment; intraoperative and histopathological findings; and follow-up data to predict thyroid gland invasion in the setting of squamous cell carcinoma of the Larynx.Results11 (16%) out of 69 patients had thyroid gland involvement on histopathological examination with mean age 63 years. Out of these 11 cases, 8 (72%) underwent primary total laryngectomy. 90% patients with thyroid gland involvement were male. 9 cases with thyroid gland involvement were staged as T4a preoperatively.ConclusionInvasion of thyroid gland by laryngeal cancer is uncommon. Unnecessary hemithyroidectomies lead to hypothyroidism and hypoparathyroidism. The study points out the clear indications of thyroid excision in patients undergoing total laryngectomy. We can suggest that total thyroidectomy should be done with total laryngectomy in cases which have gross clinical, radiological or intraoperative thyroid gland involvement, subglottic extension and thyroid cartilage invasion. This can save the patients from the brunt of unnecessary morbid hypothyroidism and hypoparathyroidism.

Thyroid Involvement in Eosinophilic Granulomatosis with Polyangiitis

Thyroid Involvement in Eosinophilic Granulomatosis with Polyangiitis

Incidence of thyroid gland invasion in advanced laryngeal cancers and its impact on disease-specific survival; a retrospective review at a tertiary care center

Background: Incidence of thyroid gland invasion in advanced laryngeal cancers is low. Ipsilateral or total thyroidectomy along with total laryngectomy has been controversial and there has been no consensus over the management of thyroid gland in advanced laryngeal cancers.Objective: To determine the frequency of thyroid gland invasion in locally advanced laryngeal squamous cell carcinoma and the risk factors associated with it.Material and methods: A retrospective review of patients with laryngeal squamous cell carcinoma operated at our center between January 2011 and December 2018 was carried out. Patients undergoing upfront or salvage laryngectomy with or without neck dissection along with hemi or total thyroidectomy were included. Histopathology reports were reviewed to record the involvement of thyroid gland.Results: Invasion of thyroid gland by squamous cell carcinoma larynx was seen in 10 (10.9%) patients out of 92. All of the cases showed direct extension of the tumor. Trans-glottic, subglottic, and tumors with extra laryngeal spread were found to be significantly associated with thyroid gland invasion. Patients with thyroid gland invasion showed higher rate recurrence.Conclusion and significance: Incidence of thyroid gland invasion in squamous cell carcinoma larynx is low, allowing us not to address thyroid routinely in patients undergoing total laryngectomy for laryngeal carcinoma.

Rare Association Between Neuroimmunological Diseases: A Possible Autoimmune Polyglandular Syndrome Type IV

Autoimmune polyglandular syndromes (APS) are a diverse group of clinical conditions characterized by loss of immune tolerance in various tissues. This condition can be diagnosed in childhood or adulthood, with changes in the components of the disease throughout life. Here, an unusual case of association between immune-mediated diseases will be addressed: Myasthenia Gravis, Systemic Lupus Erythematosus, and Celiac Disease. In this patient, each disease was expressed over time. Finally, we assume that this is a clinical form of APS type IV, due to the lack of thyroid involvement to date.
