Nipple adenoma: A clinicopathological study over a period of six years in tertiary care center.

Nipple adenoma (NA) is a rare benign neoplasm of the nipple arising from the lactiferous duct. Often seen in middle aged women, presenting as a nodule, erosive, or ulcerative lesion and associated with serous or bloody discharge. Histologically, they comprise closely arranged tubules with papillary infoldings centered around the lactiferous ducts. It is most likely clinically confused with Paget's disease and histologically with invasive breast carcinoma or its precursor lesions. The aid of immunohistochemistry is valuable in differentiating these entities and to definitively exclude malignancy. All cases with available slides and blocks, diagnosed as nipple adenoma, during the period of January 2015 to December 2021, will be identified through an appropriate query search from the pathology database. Clinico-radiological details and histopathology will be studied and analyzed. The available follow up data and clinical outcome will be assessed. Sixteen cases of nipple adenoma were studied and the median age at diagnosis was found to be 37 years. Nipple discharge and swelling were the most common presentations. Ultrasound imaging was done in 14 cases with the median size of lesion being 0.8cms. Seven underwent excision biopsy followed by histopathological examination. The most common histological pattern observed is "adenosis" pattern. Immunostains p63, smooth muscle myosin heavy chain (SMMHC) and CK5/6 were performed. Nine cases were on follow up but none had recurrence. NA is a benign entity with varied histological patterns. Histopathological examination with the aid of immunohistochemistry helps in diagnosis and to rule out other mimickers. Surgical excision is the treatment of choice.

Is There a Link between Chronic Obstructive Pulmonary Disease and Lung Adenocarcinoma? A Clinico-Pathological and Molecular Study.

Chronic Obstructive Pulmonary Disease (COPD) and lung cancer are strictly related. To date, it is unknown if COPD-associated cancers are different from the tumors of non-COPD patients. The main goal of the study was to compare the morphological/molecular profiles of lung adenocarcinoma (LUAD) samples of COPD, non-COPD/smokers and non-COPD/non-smokers, and to investigate if a genetic instability also characterized non-pathological areas. This study included 110 patients undergoing surgery for a LUAD, divided into three groups: COPD/smoker LUAD (38), non-COPD/smoker LUAD (54) and non-COPD/non-smoker LUAD (18). The tissue samples were systemically evaluated by pathologists and analyzed using a 30-gene Next Generation Sequencing (NGS) panel. In a subset of patients, tissues taken far from the neoplasia were also included. The non-COPD/smoker LUAD were characterized by a higher proliferative index (p = 0.001), while the non-COPD/non-smoker LUAD showed higher percentages of lepidic pattern (p = 0.008), lower necrosis, higher fibrosis, and a significantly lower mutation rate in the KRAS and PIK3CA genes. Interestingly, the same gene mutations were found in pathological and normal areas exclusively in the COPD/smokers and non-COPD/smokers. COPD/smoker LUAD seem to be similar to non-COPD/smoker LUAD, particularly for the genetic background. A less aggressive cancer phenotype was confirmed in non-COPD/non-smokers. The genetic alterations detected in normal lungs from smokers with and without COPD reinforce the importance of screening to detect early neoplastic lesions.

Clinicopathological study of skin tumors

Background: The diagnosis of skin tumors can cause difficulties due to their wide variety of overlapping differentiation and complicated nomenclature. Histopathological study is the most valuable means of diagnosis. Keeping in view these facts, an attempt is made to study the different varieties of tumors of the skin. Aims and Objectives: (1) The aim of this study was to study the histomorphology of different skin tumors with ancillary technique necessary and to correlate with the clinical features. (2) To find the proportion of various skin tumors. (3) To classify and identify various skin tumors and study its variation according to age, sex, site, etc., which will bear an impact on patient management and prognosis. Materials and Methods: This observational study included all cases of skin tumors received in the Department of Pathology, Kottayam Medical College, during a period of 1 year. Biopsy samples were collected, fixed in 10% formalin, processed and embedded in paraffin blocks, and stained with hematoxylin and eosin (H and E). The stained sections were studied under a microscope and histopathological diagnosis was correlated with clinical diagnosis. Results: Out of the 227 cases of skin tumors, 102 (44.9%) were male and 125 (55.1%) were female. The incidence of skin tumors peaks in individuals older than 60 years of age. The most common sites affected were face (40%). Keratinocytic tumors constituted the largest proportion of tumors (43%), followed by melanocytic tumors (31%), soft-tissue tumors (13%), appendage tumors (11%), neural (1%), and hematolymphoid tumors (1%). Conclusion: Out of the 227 cases in the present study, the clinical diagnosis of only 169 cases was correlating with the histopathological diagnosis. This emphasizes the role of microscopy in the correct diagnosis of skin tumors.

Epithelioid Sarcoma of the Oral Cavity: A Retrospective Clinicopathologic Study of Three Rare Cases

Clinicopathological Study of Resected and Recurrent Cases of Intrahepatic Intraductal Papillary Neoplasm of the Bile Duct.

This study aimed to characterize intraductal papillary neoplasm of the bile duct (IPNB) in patients undergoing initial and recurrent surgical resection and to evaluate the appropriateness of surgical treatment strategies. This study included 14 patients who underwent liver resection for intrahepatic IPNB. We assessed intraoperative and postoperative clinicopathological factors in patients undergoing both initial and recurrent surgeries. Four patients experienced recurrence after initial surgery; all underwent pancreaticoduodenectomy. Postoperative complications were classified as Clavien-Dindo Grade 1-2 in three patients and Grade IIIb in one patient. There were no in-hospital deaths. Pancreaticoduodenectomy for recurrent cases following hepatectomy for IPNB is considered safe within an acceptable range and contributes to a favorable long-term prognosis.

EBV-positive small cell neuroendocrine carcinoma of nasopharynx as a probably unique subtype of neuroendocrine carcinoma: a clinicopathologic study of three cases and literature review

BackgroundThere is currently scarcity of information on small cell neuroendocrine carcinoma of the nasopharynx (SCNEC-nasopharynx). It is believed that this type of cancer is not associated with Epstein-Barr virus (EBV) infection and is indistinguishable from classic SCNEC occurring in other organs.Materials and methodsHerein we provided 3 cases of nasopharyngeal mass in our hospital, two males and one female. On admission, these patients were considered nasopharyngeal carcinoma with lymph node metastasis, and one of them had liver metastasis. The nasopharyngeal mucosal tissues were biopsied for pathological examination including immunohistochemistry and in situ hybridization. PubMed database was searched for articles about SCNEC-nasopharynx published up to April 2024 in any language.ResultThe 3 cases had similar histological features of SCNEC in other organs but differed in rich- tumor-infiltrating lymphocytes (TILs). All of them stained for pancytokeratin (panCK) and epidermal growth factor receptor (EGFR). Case 1 and Case 2 diffusely expressed insulinoma-associated protein 1(INSM-1) and synaptophysin (Syn), Case 3 strongly stained for CD56 and Syn. Immunostaining of all 3 cases for p40, p63, TTF-1, CK20, S-100 and NUT showed negative. BRG-1, INI-1 and Rb were retained. And p53 all showed wild-type expression. The Ki-67 labeling indiced of case 1, 2, and 3 were 80%, 90%, and 80%, respectively. In situ hybridization showed strong and uniform nuclear positivity of EBV-encoded small RNAs (EBER) in the neoplastic cells of 3 cases.ConclusionEBV-positive SCNEC-nasopharynx was exactly rare. The origin of this tumor is still controversial. It may originate from EBV-infected mucosal epithelium like nasopharyngeal carcinoma. Based on our cases and relevant literature, we found EBV-positive SCNEC-nasopharynx as a probably site-specific subtype of SCNEC with differing pathogenetic mechanism. The subtype not only virus positivity but also that it was associated with TILs and did not show p53 or Rb alterations by immunohistochemistry. It may be more responsive to treatment and have a better prognosis than classic SCNEC. We will continue to follow-up these patients and collect additional cases to further understand the unique biology of this rare solid tumor.

Management of a dentigerous cyst; a ten-year clinicopathological study

BackgroundDentigerous cysts, deemed of developmental origin, are benign odontogenic cysts characterized by a gradual growth rate. Their occurrence is twice as prevalent in men compared to women. These cysts are recognized as the most frequent developmental cysts affecting the jaws, with a typical manifestation in individuals aged 20 to 40, while infrequently identified in young children. Notably, dentigerous cysts have the potential to attain significant dimensions, resulting in painless enlargement of the jaw and subsequent deformation.ObjectivesTo assess the clinicopathological features and management of ten years of experience with dentigerous cysts.MethodsA challenging cases were reported from reviewed records of the patients who were treated by the surgical intervention of various dentigerous cysts throughout the period of ten years, 2012–2022 and only histologically confirmed cases were selected, at Ramadi Teaching Hospital in addition to Rashid, Razi, Zuhur Private Hospitals and private clinics in Iraq.Results76 patients were included in this clinicopathological research. The highest age group affected was ≤ 18 years (68.4%), 54% were male, the mandible was more affected (63.1%) than the maxilla (36.9%). Marsupialization was applied to 30.3% of the cases, while enucleation was carried out in 69.7%.ConclusionsThe significance of meticulous examination of radiographs and the consequences associated with undetected and untreated ailments is affirmed by this case study. A comprehensive understanding of oral pathology serves as a valuable resource for dentists, facilitating accurate diagnosis, appropriate referrals, and the provision of anticipatory guidance to patients striving to achieve optimal oral health across various age groups.

Clinicopathological Study of Gastroduodenal Biopsies and Correlate with Endoscopic Findings in Northeast India- One- Year Cross-sectional Study in a Tertiary Care Centre

Background: The gastrointestinal tract (GIT) is a hollow muscular tube extending from the oral cavity to the anus. Acid peptic disease is among the most common disorders affecting this region globally, caused by an imbalance between acid secretion and gastric mucosal defenses. Endoscopy has enhanced the accuracy and early histologic diagnosis of mucosal lesions. This cross-sectional study examines 100 gastroduodenal biopsies over a one-year period. Methods: The study categorized histopathological findings from gastro-duodenal biopsies collected via endoscopy and analyzed their correlation with endoscopic results. Results: Gastroduodenal lesions were more prevalent in males, particularly in the fifth decade of life. Endoscopic findings included 12 normal cases, 31 ulcers, 15 erosions, 4 polyps, and 38 malignancies. Among the 38 malignancies, 10 were premalignant, 23 were diagnosed as gastric carcinoma, and 4 as duodenal carcinoma, demonstrating a strong correlation between endoscopic and histopathological findings. Conclusion: Endoscopic gastroduodenal biopsies are instrumental in diagnosing both benign and malignant lesions across various age groups and sites. The combination of endoscopy and histopathological analysis provides a powerful diagnostic tool for better patient management.

Diagnostic Errors in Obstetric Morbidity and Mortality: Methods for and Challenges in Seeking Diagnostic Excellence.

Pregnancy-related morbidity and mortality remain high across the United States, with the majority of deaths being deemed preventable. Misdiagnosis and delay in diagnosis are thought to be significant contributors to preventable harm. These diagnostic errors in obstetrics are understudied. Presented here are five selected research methods to ascertain the rates of and harm associated with diagnostic errors and the pros and cons of each. These methodologies include clinicopathologic autopsy studies, retrospective chart reviews based on clinical criteria, obstetric simulations, pregnancy-related harm case reviews, and malpractice and administrative claim database research. We then present a framework for a future study of diagnostic errors and the pursuit of diagnostic excellence in obstetrics: (1) defining and capturing diagnostic errors, (2) targeting bias in diagnostic processes, (3) implementing and monitoring safety bundles, (4) leveraging electronic health record triggers for case reviews, (5) improving diagnostic skills via simulation training, and (6) publishing error rates and reduction strategies. Evaluation of the effectiveness of this framework to ascertain diagnostic error rates, as well as its impact on patient outcomes, is required.

Upper motor neuron-predominant motor neuron disease presenting as atypical parkinsonism: A clinicopathological study.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by upper and lower motor neuron signs. There are, however, cases where upper motor neurons (UMNs) are predominantly affected, leading to clinical presentations of UMN-dominant ALS or primary lateral sclerosis. Furthermore, cases exhibiting an UMN-predominant pattern of motor neuron disease (MND) presenting with corticobasal syndrome (CBS) have been sparsely reported. This study aims to clarify the clinicopathological features of patients with UMN-predominant MND. We reviewed 24 patients with UMN-predominant MND with TDP-43 pathology in the presence or absence of frontotemporal lobar degeneration. Additionally, we reviewed the medical records of patients with pathologically-confirmed corticobasal degeneration (CBD) who received a final clinical diagnosis of CBS (n = 10) and patients with pathologically-confirmed progressive supranuclear palsy (PSP) who received a final clinical diagnosis of PSP syndrome (n = 10). Of 24 UMN-predominant MND patients, 20 had a clinical diagnosis of an atypical parkinsonian disorder, including CBS (n = 11) and PSP syndrome (n = 8). Only two patients had antemortem diagnoses of motor neuron disease. UMN-predominant MND patients with CBS less frequently exhibited apraxia than those with CBD, and they were less likely to meet clinical criteria for possible or probable CBS. Similarly, UMN-predominant MND patients with PSP syndrome less often met clinical criteria for probable PSP than PSP patients with PSP syndrome. Our findings suggest that UMN-predominant MND can mimic atypical parkinsonism, and should be considered in the differential diagnosis of CBS and PSP syndrome, in particular when criteria are not met.

Clinicopathological Study of Fibroepithelial Lesions of the Breast in a Tertiary Care Hospital in South India.

Introduction Fibroepithelial lesions of the breast mainly include fibroadenoma and phyllodes tumors with overlapping morphological features and varied clinical behavior. This study aims to determine the histopathological spectrum of fibroepithelial lesions of the breast in a tertiary care hospital. Methods This is a cross-sectional study that was carried out in the pathology department from 1stJanuary 2015 to 31stDecember 2023. Relevant data of all fibroepithelial lesions reported during the study period were retrieved from the medical records, tabulated, and analyzed. The Pearson chi-square test was used to determine the significant association between the various clinicopathological parameters of fibroepithelial lesions. A p-value of less than 0.05 was taken as statistically significant. Results Out of a total of 195 fibroepithelial lesions, 185 (95%) were fibroadenoma, 07 (3.5%) were phyllodes tumors, and three (1.5%) were fibroadenoma with tubular adenoma. The most common age group was 21 to 40 years, with the majority of phyllodes tumors being more than 5 cm in size compared to fibroadenomas. The association between the clinicopathological characteristics such as age of patients, tumor size, and histological grade was statistically insignificant in this study. Conclusions The implementation and usage of morphological diagnostic criteria will help in diagnosing and categorizing this broad group of fibroepithelial lesions, thereby facilitating appropriate treatment forpatients.

Clinical spreading of muscle weakness in amyotrophic lateral sclerosis (ALS): a study in 910 patients

BackgroundNeuroanatomical staging of sporadic amyotrophic lateral sclerosis (ALS) indicates that neurodegeneration may spread corticofugally.MethodsWe conducted an observational study to define the initial sites of disease onset and the clinical progression (‘spreading patterns’) of motor deficits in a cohort of 910 ALS patients in Germany.ResultsMean age of ALS onset was 59.0 ± 12.6 years for males and 61.2 ± 10.5 years for females, the mean ALSFRS-R was 35.1 ± 9.2, and 7.7% of the cohort reported a family history. Onset of motor symptoms was bulbar/upper limb in 26.8%/35.9%, the right arm initially being slightly more often affected than the left (18.5% vs.16.3%). Testing on concordance of handedness and onset in the dominant arm did not reach significance. Lower limb onset was observed in 37.3%. Unilateral limb onset patients reported horizontal spreading about three times more often than vertical spreading. 71/244 bulbar onset patients reported spreading pattern to the legs, and 17/339 lumbar onset patients reported spreading secondarily to the bulbar region.DiscussionOur results indicate that, although the phenotype of so-called ‘spinal’ or ‘intraspinal’ spreading predominated, we also observed an additional clinical spreading pattern: 29.1% of patients with bulbar onset experienced spreading clinically to the legs (vice versa in 5.0% of lumbar onset patients). For obvious neuroanatomical reasons, this pattern hardly can be explained solely by a ‘spinal’ or an ‘intraspinal’ pattern of spreading. Instead, these findings complement insights from previous clinical and clinicopathological studies supporting a cortical initiation of ALS.

Non-small cell lung carcinoma with clear cell features: a clinicopathologic, immunohistochemical, and molecular study of 31 cases.

Non-small cell lung carcinoma with predominantly clear cell features is a rare histologic presentation of lung carcinoma. We have examined 31 cases of lung carcinomas showing extensive clear cell features. The patients were 10 women and 21 men aged 47-92years (mean: 70years). The tumors showed a predilection for the right upper and lower lobes and measured from 0.8 to 9.5cm (mean: 4.2cm). By immunohistochemistry, 9 cases were typed as adenocarcinoma, 19 cases as squamous cell carcinoma, and 3 showed a "null" phenotype with complete loss of markers for adenocarcinoma or squamous cell carcinoma. Most cases that typed as adenocarcinoma showed a solid growth pattern. A subset of the solid adenocarcinoma cases showed a distinctive "pseudosquamous" morphology. Next-generation sequencing was performed in 20 cases and showed a variety of molecular alterations. The most common abnormalities were found in the TP53 gene (9 cases), FGFR gene family (8 cases), KRAS (5 cases), AKT1 (5 cases), and BRAF (3 cases). Clinical follow-up was available in 21 patients; 16/21 patients died of their tumors from 6months to 12years after initial diagnosis (mean: 4.2years, median: 1.5years). Four patients were alive and well from 4 to 27years (mean: 11.5years, median: 7.5years); all were pathologic stage 1 or 2. NSCLC with clear cell features can display aggressive behavior and needs to be distinguished from various other tumors of the lung that can show clear cell morphology. The identification of targetable molecular alterations in some of these tumors may be of value for therapeutic management.

Expanding the Spectrum of NUTM1 -Rearranged Sarcoma : A Clinicopathologic and Molecular Genetic Study of 8 Cases.

Apart from the lethal midline carcinoma (NUT carcinoma), NUTM1 translocation has also been reported in mesenchymal tumors, but is exceedingly rare. Here, we describe a series of 8 NUTM1 -rearranged sarcomas to further characterize the clinicopathologic features of this emerging entity. This cohort included 2 males and 6 females with age ranging from 24 to 64 years (mean: 51y; median: 56y). Tumors occurred in the colon (2), abdomen (2), jejunum (1), esophagus (1), lung (1) and infraorbital region (1). At diagnosis, 6 patients presented with metastatic disease. Tumor size ranged from 1 to 10.5cm (mean: 6cm; median: 5.5 cm). Histologically, 4 tumors were composed of primitive small round cells to epithelioid cells intermixed with variable spindle cells, while 3 tumors consisted exclusively of small round cells to epithelioid cells and 1 tumor consisted predominantly of high-grade spindle cells. The neoplastic cells were arranged in solid sheets, nests, or intersecting fascicles. Mitotic activity ranged from 1 to 15/10 HPF (median: 5/10 HPF). Other features included rhabdoid phenotype (4/8), pronounced nuclear convolutions (2/8), prominent stromal hyalinization (2/8), focally myxoid stroma (1/8), foci of osteoclasts (1/8), and necrosis (1/8). By immunohistochemistry, all tumors showed diffuse and strong nuclear staining of NUT protein, with variable expression of pancytokeratin (AE1/AE3) (2/8), CK18 (1/8), CD99 (3/8), NKX2.2 (2/8), cyclin D1 (2/8), desmin (2/8), BCOR (2/8), S100 (1/8), TLE1 (1/8), and synaptophysin (1/8). Seven of 8 tumors demonstrated NUTM1 rearrangement by fluorescence in situ hybridization analysis. RNA-sequencing analysis identified MXD4::NUTM1 (3/7), MXI1::NUTM1 (3/7), and MGA::NUTM1 (1/7) fusions, respectively. DNA-based methylation profiling performed in 2 cases revealed distinct methylation cluster differing from those of NUT carcinoma and undifferentiated small round cell and spindle cell sarcomas. At follow-up (range: 4 to 24mo), 1 patient experienced recurrence at 8.5 months, 4 patients were alive with metastatic disease (5, 10, 11, and 24mo after diagnosis), 3 patients remained well with no signs of recurrence or metastasis (4, 6, and 12mo after diagnosis). Our study further demonstrated that NUTM1 -rearranged sarcoma had a broad range of clinicopathologic spectrum. NUT immunohistochemistry should be included in the diagnostic approach of monotonous undifferentiated small round, epithelioid to high-grade spindle cell malignancies that difficult to classify by conventional means. DNA-based methylation profiling might provide a promising tool in the epigenetic classification of undifferentiated sarcomas.

Neuropathological Lesions and Cognitive Abilities in Black and White Older Adults in Brazil

Race differences in dementia prevalence and incidence have previously been reported, with higher dementia burden in Black decedents. However, previous neuropathological studies were conducted mostly in convenience samples with White participants; conducting clinicopathological studies across populations is crucial for understanding the underlying dementia causes in individuals from different racial backgrounds. To compare the frequencies of neuropathological lesions and cognitive abilities between Black and White Brazilian adults in an autopsy study. This cross-sectional study used samples from the Biobank for Aging Studies, a population-based autopsy study conducted in Sao Paulo, Brazil. Participants were older adults whose family members consented to the brain donations; Asian participants and those with missing data were excluded. Samples were collected from 2004 to 2023. Neuropathologists were masked to cognitive outcomes. Race as reported by the deceased's family member. The frequencies of neurodegenerative and cerebrovascular lesions were evaluated in 13 selected cerebral areas. Cognitive and functional abilities were examined with the Clinical Dementia Rating Scale. The mean (SD) age of the 1815 participants was 74.0 (12.5) years, 903 (50%) were women, 617 (34%) were Black, and 637 (35%) had cognitive impairment. Small vessel disease (SVD) and siderocalcinosis were more frequent in Black compared with White participants (SVD: odds ratio [OR], 1.74; 95% CI, 1.29-2.35; P < .001; siderocalcinosis: OR, 1.70; 95% CI, 1.23-2.34; P = .001), while neuritic plaques were more frequent in White compared with Black participants (OR, 0.61; 95% CI, 0.44-0.83; P = .002). Likewise, Alzheimer disease neuropathological diagnosis was more frequent in White participants than Black participants (198 [39%] vs 77 [33%]), while vascular dementia was more common among Black participants than White participants (76 [32%] vs 121 [24%]). Race was not associated with cognitive abilities, nor did it modify the association between neuropathology and cognition. In this cross-sectional study of Brazilian older adults, Alzheimer disease pathology was more frequent in White participants while vascular pathology was more frequent in Black participants. Further neuropathological studies in diverse samples are needed to understand race disparities in dementia burden.

Clinicopathological study of thyroid gland cancer among selected sample Basrah province between 2019-2022

Background. Thyroid cancer (TC) is the most prevalent cancer within the endocrine system and the head and neck region. Its incidence has been on the rise in Iraq over the past few decades, primarily owing to papillary thyroid carcinoma. This study’s objective is to explore the pathological variants, frequency, and demographic characteristics of TC in a sample of Basrah’s population and subsequently compare these elements with data from other regions in Iraq and globally. Methods. This study is a single-institutional retrospective review conducted at the Department of Pathology within Ports Teaching Hospital in Basrah, Iraq. We analyzed slides of thyroid tumors stained by Hematoxylin and Eosin (H&amp;E) and biometric data gathered from histopathological reports. The cases for this study were identified between 2019 and 2022. Results. In this study, 51 cases were examined, comprised of six males and 45 females. The average age and histopathology patterns were analyzed, finding that the most common type of TC was the classic form of papillary thyroid carcinoma, as seen in 16 cases. The study noted a predominant female presence, accounting for 88.2% of the cases, while males comprised 11.8%. The median age among all subjects was 38 years. Conclusions. A review of all slides featuring thyroid tumors stained with H&amp;E, combined with biometric data from histopathological reports, shows an increasing incidence of TC in Basrah City, Iraq. Predominantly, cases of papillary thyroid carcinoma outnumber those of follicular carcinoma.
