Pleomorphic adenoma of hard palate: Review of updated literature and "case report".

Pleomorphic adenoma (PA) is a rare benign tumor mainly affecting the major salivary glands, known for its diverse histological appearances that can mimic malignancies. When it occurs in the hard palate it present diagnostic and management challenges compared to other sites due to the anatomical location and potential proximity to critical structures. This case reports a rare presentation PA starting as an ulcer, alongside a review of rare cases of PA reported in last 5 years. We aim to highlight clinical challenges and emphasize the need for awareness in diagnosis of this diverse entity amongst the clinicians before reaching a definitive conclusion. A 41-year-old female reported an asymptomatic large swelling on the right side of the posterior palatal region. Clinical diagnosis revealed a firm, rubbery, and non-tender swelling of approximately 4 cm × 4 cm diameter. A triangular incisional biopsy was performed to confirm the diagnosis. The histopathological evaluation confirmed the presence of a PA with a well-encapsulated and compressed salivary gland. A wide surgical dissection was made to remove the entire encapsulated tumor mass, including the mucoperiosteum and eroded bone of the palate. The borderline of the tumor was carefully identified in the surrounding healthy tissue. The hemostasis was obtained using a simple interrupted suture. The diagnosis of PA is difficult as it usually involves extensive squamous and mucous metaplasia, confusing it with malignant disorders. Histopathological and clinical examinations are important for differentiating this lesion from other tumors. Complete surgical excision is reported as the first line of treatment.

Rapid growth of calcified amorphous tumor with mitral annulus calcification: a case report

BackgroundCalcified amorphous tumor (CAT) of the heart is a rare, non-neoplastic cardiac mass with mitral valves and annuli being the most common sites. The presence of mitral annular calcification (MAC) is associated with an increased risk of stroke or other systemic embolisms. Here, we report a case of CAT showing rapid growth with MAC and investigate the link between the two.Case presentationA 71-year-old man presented at our hospital with dyspnea and had been undergoing hemodialysis for 26 years for chronic glomerulonephritis. Transthoracic echocardiography (TTE) revealed moderate mitral stenosis with bulky MAC. Two months later, the patient developed progressive dyspnea, and follow-up TTE revealed a highly mobile mass (8 × 5 mm) attached to the left ventricular (LV) side of the posterior MAC. He underwent surgery because of congestive heart failure and a high risk of embolization. Surgical inspection revealed that the tumor was attached beneath the P3 segment of the mitral valve on the LV side and was removed. When removing the MAC, toothpaste-like contents drained from the encapsulated mass inside the MAC at the P3 segment, where the tumor was located. After reconstructing the posterior mitral annulus defect with a bovine pericardial patch, mitral valve replacement with a mechanical prosthesis, a maze procedure, and left appendage closure were performed. Histopathological examination revealed that the excised tumor contained fibrin and calcium deposits. The mass was diagnosed as a CAT.ConclusionsCAT may be one of the causes of stroke induced by MAC. Routine follow-up echocardiography should be recommended for patients with MAC, especially those undergoing hemodialysis.

Pleomorphic Adenoma of the Upper Lip: A Case Report

Pleomorphic adenoma (PA) is a commonly occurring benign tumor originating in the salivary glands. The incidence is mostly in the parotid glands (85%) followed by minor salivary glands (10%). Pleomorphic adenoma from minor salivary glands of the lips is a rare neoplasm. Here, we present a case of a patient with PA in the upper lip, reporting a common neoplasm in a rare site. A 82-year-old male with a slowly progressing swelling that occurred 20years ago on the upper white lip. This tumor is not associated with pain and tenderness. The mass was about 1.5x1.5cm sized, circumscribed, sessile and firm on the external upper lip without oral side bulging (Fig. 1). The tumor was removed completely with a elliptical incision under local anesthesia. The encapsulated mass was measured 0.9x0.9x0.6cm. On histology, a well-circumscribed growth was seen comprising epithelial and stromal components. The epithelial component formed glandular structures lined by round-to oval cells having small nuclei, pink cytoplasm and myoepithelial basal cell layer while the stroma had a fibromyxoid appearance(Fig. 2). Postoperatively wound was well healed without recurrence after 6months. Pleomorphic adenoma of the upper lip is a rare neoplasm, especially not intraoral growth. For aesthetic good result, the mass was removed without hesitation. It is required a high index of suspicion and a long-term follow-up because it could recur and rarely be transformed into malignancy.

Epipericardial Fat Necrosis and Covid-19.

Epipericardial fat necrosis (EFN) is a rare and self-limiting cause of acute chest pain. We describe a case of EFN in a patient with a recent coronavirus disease (COVID-19). A 55-year-old male presented with a sudden onset of left-sided pleuritic chest pain for the past two days. The patient was diaphoretic, tachypneic, and tachycardic. Acute coronary syndrome was ruled out. A computed tomography (CT) pulmonary angiogram revealed an ovoid encapsulated fatty mass surrounded by dense appearing tissue. Patient symptoms improved remarkably with a short course of non-steroidal anti-inflammatory drugs (NSAIDs). EFN typically presents with a sudden onset of excruciating chest pain. Misdiagnosis, under-diagnosis, and mismanagement are unavoidable. EFN is incidentally diagnosed on CT scan. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infects visceral adipose tissue and appears to increase the risk of EFN by promoting inflammatory cytokine production and death of adipocytes. EFN is a rare cause of acute chest pain. SARS-CoV-2 is likely to induce EFN. This rare clinical entity should be considered in the differential of acute chest pain especially in patients with active or recent COVID-19. Epipericardial fat necrosis (EFN) is a rare cause of acute pleuritic chest pain that is often misdiagnosed and mismanaged.SARS-CoV-2 can possibly increase the risk of EFN and this entity should be considered in the differential of chest pain, especially in patients with active or recent coronavirus disease (COVID-19).Clinician awareness of EFN and its potential association with COVID-19, can reduce unnecessary testing and emotional distress.

An Unusual Case of Scrotal Aggressive Angiomyxoma (AAM) Masquerading as Non-Reducible Inguinal Hernia – A Rare Case Report and Literature Review

This case report details a rare instance of scrotal Aggressive Angiomyxoma (AAM) in a 62-year-old male, presenting with a gradually enlarging mass masquerading as a non-reducible inguinal hernia. AAM, predominantly found in adult females, is an exceptionally uncommon occurrence in men. The diagnostic challenge lay in the rarity of male cases and the tumor’s mimicry of common conditions like inguinal hernia. Upon physical examination, a non-reducible, non-tender swelling extending from the right inguinal region to the scrotal sac was noted. Radiological investigations initially suggested a scrotal mass or non-reducible inguinal hernia. Intraoperative exploration revealed a large encapsulated cystic mass, measuring 12 x 8 cm, originating from the inguinal ligament. Histopathological examination confirmed the diagnosis of aggressive angiomyxoma, characterized by spindle-shaped tumor cells, thick-walled blood vessels, and myxoid texture. The discussion underscores the diagnostic complexities of AAM, emphasizing the necessity of histopathological examination for conclusive diagnosis. A review of male AAM cases in the literature highlights similarities with female cases, supporting the expression of estrogen (ER) and progesterone receptors (PR). Surgical removal with clear margins is the primary treatment, although recurrence rates vary. The potential role of hormonal therapy, especially in ER and PR positive cases, is noted but requires further exploration. In conclusion, this rare case sheds light on the clinical and pathological characteristics of scrotal AAM in men. The diagnostic journey underscores the importance of considering AAM in the differential diagnosis of scrotal masses. Long-term follow-up is crucial due to the tumor’s propensity for local recurrence, making this case a valuable addition to the limited literature on male AAM.

Clinical Application of Computed Tomography in the Surgical Treatment of Submandibular Sialocele and Sialoliths in Dog

A 10-year-old, 8-kg mixed-breed dog presented with a painless, soft, and tender submandibular swelling. Radiographs revealed an 8x6 cm ventral cervical mass with radiopaque spots. Fine needle aspiration showed high viscosity and yellow-tinged fluid, indicative of an inflammatory sialocele. After drainage, carprofen (4.4 mg/kg) was administered daily for one week, followed by prednisone (0.5 mg/kg) for the second week. However, the mass recurred after one month, necessitating a computed tomography (CT) scan for surgical management. CT imaging demonstrated an encapsulated fluid-attenuating mass in the submandibular region, containing sludges and calcified materials. Surgical excision confirmed a submandibular mucocele with sialoliths. Infrared spectroscopy revealed a high protein concentration in the sialoliths. The CT scan facilitated accurate diagnosis and informed the treatment plan for this canine cervical mass, encompassing submandibular mucocele and sialolithiasis.

Successful management of a giant retroperitoneal ancient schwannoma mimicking malignant tumors: A case report and literature review

Introduction and Importance: Schwannomas, originating from Schwann cells surrounding nerve sheaths, tend to be slow-growing. Among these, giant ancient schwannomas are remarkable for their rare occurrence and their capacity for substantial growth and regressive changes. Furthermore, the expansiveness and flexibility of the retroperitoneal space often conceal the symptoms of retroperitoneal schwannomas, leading to delayed diagnosis and allowing these tumors to grow significantly and become large and long-standing before detection. Case Presentation: A 24-year-old man presented with left flank pain and a growing abdominal bulge in the left upper quadrant. Computed tomography scan revealed a 15×15×10 cm lytic expansile lesion. Consequently, the encapsulated mass was surgically excised and diagnosed as an ancient retroperitoneal schwannoma through histological and immunohistochemical studies. Clinical Discussion: Comprehensive preoperative planning and a multidisciplinary strategy are imperative for the complete excision of schwannomas. These tumors can present diagnostic complexities, particularly due to nuclear atypia and pleomorphism, which might lead to misinterpretation regarding malignancy. Despite the risks associated with percutaneous biopsies, the low mitotic count is a critical diagnostic factor. Our study underscores the consensus that the definitive diagnosis should rely on postoperative histopathological findings, highlighting the importance of accurate assessment. Conclusion: Rare giant retroperitoneal ancient schwannomas pose diagnostic challenges due to their rarity, lack of distinct symptoms, and atypical locations. This study presents a successful case and management.

Anatomical and Surgical Implications of the Usage of Bichat Fat Pad in Oroantral Communication, Maxillary, Palatal, and Related Surgeries-Narrative Review.

The buccal fat pad, also called the Bichat's fat pad (BFP), is an encapsulated fat mass located in the cheek. This type of specialized fat mass can be used both as a pedicular or free graft in various surgeries and approaches. Due to its easy access from the oral cavity approach, it is commonly used for oroantral and palatal fistula closure. The knowledge of its anatomy and surrounding tissues plays a role in its mobilization and suturing onto the desired defect in the palatal or maxillary region. The BFP is mostly associated with the primary approach used for a fistula or bone surgery. Alternatively, the procedure can be performed with a single approach incision, which does not compromise the appearance or the function of the operating or adjacent areas. The most important inclusion criteria for BFP usage and surgical limitations are highlighted. The BFP is used for multiple purposes in reconstructive and oncology surgery and also has its use in esthetic and facial contouring procedures. The amount, volume, and shape of the BFP are mostly associated with the scope of their usage. The aim of the following narrative review is to present the surgical and anatomical implications of fat pads in maxillary and palatal surgeries.

Follicular Thyroid Adenoma with Papillary Architecture

A 23-year-old woman underwent left thyroid lobectomy and isthmusectomy for a 2 cm diameter firm mass on the left side of the neck that was also visualized on ultrasonography. The specimen consisted of a 22-gram thyroid gland composed of the left lobe, isthmus and a pyramidal lobe. Cut section of the left lobe showed a 3.5 cm diameter solitary, discrete and encapsulated mass with a tan lobulated and solid cut surface. The rest of the thyroid tissues had red-brown meaty cut surfaces.
 Microscopic section shows a follicular-patterned proliferation enclosed by a thin fibrous capsule with frequent Sanderson polster-like papillary excrescences. (Figures 1 and 2) Both the follicular and the papillary structures are lined by cuboidal to columnar follicular epithelial cells that had ample eosinophilic to pale cytoplasm and uniformly sized, minimally enlarged, generally round, and monolayered nuclei without nuclear grooving, folds, pseudoinclusions, and chromatin clearing. There are no mitotic figures seen. Some of the papillary structures have delicate vascular cores. (Figure 3) There are no psammoma bodies noted. The follicles contain variable amounts of pale eosinophilic colloid ranging from colloid-poor crowded follicles to those with ample colloid that have frequent peripheral scalloping. (Figure 4) Exhaustive sections failed to disclose capsular or vascular invasion. Based on the microscopic features, a diagnosis of follicular adenoma with papillary architecture was rendered.

Malignant Peripheral Nerve Sheath Tumors of the Brachial Plexus - A Case Report

Introduction: Malignant peripheral nerve sheath tumors represent all the neoplasias developed at the expense of cells located in the peripheral nerve sheaths. Complete surgical excision with microscopically healthy edges remains the only curative treatment. Through a clinical case, and a review of the literature, we will report our experience in the management of a tumor of the peripheral nerve sheaths. Observation: Madam K.L, 34 years old, admitted for management of a spontaneously painful left axillary mass, and in whom the clinical examination found a patient, in good general condition, with the presence of a 8cm left axillary mass hard to fixed palpation in relation to the 2 planes, painless on palpation. Thoracic computed tomography revealed an encapsulated left axillary tissue mass compressing the axillary pedicle measuring 84mm*67mm with areas of necrosis. MRI had objectified the presence of a fusiform mass extended to the inter-scalene space most likely evoking a tumor of the malignant peripheral nerve sheaths. The patient had undergone complete tumor excision with section of the left subclavian artery and end-to-end anastomosis, with simple postoperative consequences. Conclusion: MPNSTs are rare tumors. Surgery occupies an essential place in the treatment of this disease, it must be planned in order to avoid vascular and nervous risks. Radiotherapy may be indicated as an adjuvant or in the event of an unhealthy margin.

Laparoscopic assisted removal of large ovarian mass causing precocious puberty in an infant—a case report

BackgroundSex cord and stromal tumors are a heterogeneous group of tumors that arise from gonadal sex cord cells, gonadal stromal cells, or both. They are divided into pure stromal tumors, pure sex cord tumors, and mixed tumors. Some of these tumors are hormonally active, producing androgens and estrogens, and may therefore exhibit virilization or excess estrogen. Sertoli-Leydig cell tumors are rare tumors belonging to mixed tumors representing less than 0.5% of ovarian tumors. Few cases have been reported in the medical literature.Case presentationWe report the case of a 1-year-old girl who was admitted for breast lumps and pubic hair with intermittent painless vaginal bleeding in the past 2 weeks. The abdominal examination objectified the presence of an intraperitoneal mass to which an abdominal ultrasound and computerized tomography (CT) scan had confirmed the presence of a right ovarian mass. A laparoscopy was performed which showed an encapsulated mass arriving from the right ovary replacing the normal ovarian tissue. Laparoscopic-assisted removal of the entire mass was done. The postoperative course was uneventful. The histopathological study demonstrated an intermediately differentiated Sertoli cell tumor with an intact capsule, no lymphovascular invasion, or heterologous elements (TNM stage 1).ConclusionsAlthough Sertoli-Leydig tumors are commonly seen after the second decade of life in young women, their discovery before puberty is not uncommon. Mass syndrome and signs of virilization are two frequently reported signs that should prompt the clinician to mention this entity among the differential diagnoses. The first-line radiological examination is pelvic ultrasound. The treatment is mainly based on surgery. The prognosis is excellent especially if the tumor is well differentiated.

Saphenous Nerve Schwannoma: A Rare Differential Diagnosis of Knee Pain in Children

Schwannomas are uncommon benign tumors of the peripheral nerves with a low risk of malignant transformation. They rarely affect children, can affect any part of the body but rarely occur in the lower extremity and typically present with a palpable mass, pain or neurological signs. Imaging helps to orient the diagnosis and anatomopathological examination helps to confirm it. We report a case of a 12-year-old girl who presented with left knee pain with subcutaneous mass overlying the tibial tuberosity medially. Clinical examination revealed a positive Tinel's sign. Magnetic resonance imaging (MRI) of the knee was performed, which revealed an encapsulated subcutaneous soft tissue mass overlying the tibial tuberosity medially, eccentric to the course of the infrapatellar branch of the saphenous nerve. The patient was operated with total intracapsular excision of the lesion and the anatomopathological study of the surgical specimen came back in favor of a schwannoma. Postoperatively, the patient showed a good recovery with disappearance of pain and swelling.

Lipoblastome de la nuque chez un enfant

abstract We report the case of a male child aged 3 years who was consulted for a right deviated neck tumor, movable with the superficial plane and fixed with the deep plane, measuring 8 cm in length. It was firm, painless, without associated inflammatory signs (A), Cervical scan showed a tumoral process of the right nuchal parts, lobulated contour, with double fatty component containing fine partitions and tissue enhanced after injection of iodinated contrast (ICP), measuring 50*43*55mm in diameter (B), Patient admitted to the operating room: posterior transverse incision of the neck. Surgical exploration revealed an encapsulated mass very much adherent to the different musculoaponeurotic planes that it was pushing back without invading them. The mass was completely resected without capsular opening, following the cleavage planes between it and the planes (C). It measured 6.5 cm in length and contained several fatty lobules grouped in clusters (D). Anatomopathological examination confirmed a lipoblastoma.

A RARE CASE REPORT OF GLOMUS TUMOUR OVER MARGIN OF LOWER LID OF LEFT EYE

Introduction: Glomus tumours are rare, benign tumours of vascular origin, arising from the glomus body. Glomus tumours are neoplasms of mesenchyme derived from glomus bodies. Glomus tumours present as a purple or pink vascular lesion that can be confused with a vascular neoplasm such as hemangioma. In this case we are reporting a rare presentation of glomus tumour over lower lid. A 10 year old female child presented with lesion over left lower Case Report: lid since 3 months which was painless and progressive. On examination a 0.3x0.3 cm subcutaneous pink non encapsulated mass is seen over medial canthus of left eye. Mass was excised and subjected to histopathological examination which conrmed the diagnosis of glomus cell tumour(glomangioma). Postoperative period was uneventful with no recurrence for last 6months. Conclusion: All excised eyelid lesions should undergo detailed Histopathological evaluation and glomus tumour should be considered as one of the differential diagnosis in patients presenting with eyelid mass.

Gastrointestinal: A wandering pancreatic adenocarcinoma.

A 79-year-old woman was referred to our hospital complaining of upper abdominal pain. She had no history of diabetes mellitus or other malignant diseases. Blood analysis showed no atypical findings other than elevated levels of CEA and Dupan-2. Contrast-enhanced computed tomography (CT) showed a 50 × 40-mm mass with poor contrast and irregular margins in the head of the pancreas (Fig. 1). Invasion into the superior mesenteric artery and portal vein was also evident. Histopathological examination of a specimen from endoscopic ultrasound-guided fine needle aspiration revealed adenocarcinoma. We diagnosed the mass as locally advanced unresectable pancreatic adenocarcinoma, and decided to perform chemoradiotherapy in order to help control the cancer and slow down its growth. To design radiotherapy, we performed CT on inhalation and free-breathing. The pancreatic mass was on the right side of the spine on inhalation, but surprisingly appeared on the left side of the spine on free-breathing (Fig. 2). We administered radiation at 1.8 Gy/day with fixation of the mass using a body shell and also administered gemcitabine. On day 8 after therapy, the patient developed multiple cerebral infarctions associated with Trousseau syndrome. She subsequently received best supportive care. In general, pancreatic masses have been considered immovable, because the pancreas is fixed to the retroperitoneum with the duodenum. The anterior surface of the pancreas is covered by parietal peritoneum and the inferior border abuts the root of the transverse mesocolon. A loose connective tissue layer, known as the fusion fascia of Treitz in the region of the head of the pancreas and as the fusion fascia of Told in the region of the body and tail, is coherent with the posterior of the pancreas. Some reports have pointed out that the pancreas can change position in some patients, particularly women. However, few reports in the English literature have described a wandering pancreatic mass. A case of wandering neuroendocrine tumor of the head of the pancreas has been reported, involving an encapsulated mass. In that case, CT showed a shift of the large mass in the pancreas from the right to the left side of the aorta. However, wandering pancreatic adenocarcinoma has not previously been reported. Malrotated pancreas or pancreatic volvulus has been reported with wandering spleen as a very rare clinical entity, but the present case demonstrated no clinical complications, such as mobile spleen or other abdominal organs. In our case, acquired pancreatic mobilization due to tissue weakening was speculated as the cause of motility. Pancreatic carcinoma should also be considered among the differential diagnoses for mobile abdominal mass.

Testicular Epidermoid Cyst: A Rare Case Report.

Introduction an importanceTesticular epidermoid cysts (TECs) are rare benign testicular neoplasms. Recently, testicular epidermoid cysts (TECs) are listed as teratoma of prepubertal type, however it is still difficult to differentiate the epidermoid cyst from malign testicular tumor. Therefore, we would like to report testicular epidermoid cyst at our institution.Case presentationA 67-year-old man from Indonesia, presented with chronical painless mass of testis since one year ago. On physical examination obtained normal penile structure with descended testicles, palpable intrascrotal mass with size of 10 × 7 × 5 cm, firm consistency, immobile, without any tenderness, and no lymphadenophaty in groin. Scrotal USG showed intratesticular mass, homogenous parenchym, showed no vascularization during Doppler examination. Histopathological examination revealed the specimen of right scrotum with size of 12.5 cm × 8.5 cm × 6.1 cm with red-brownish colored, during lamellation, obtained encapsulated mass with size of 12.2 cm × 7.9 cm × 6 cm, hollowed space filled with porridge-like texture with capsule thickness of 0.1–0.3 cm.Clinical discussionEpidermoid cysts are benign lesions occurring on the skin usually, however, it rarely occurs in intratesticular area. Most of the cases (60%) presented with the typical onion-ring phenomenon. Histopathological findings commonly revealed typical well-defined cyst lined by a fibrous membrane. No skin appendages are found in the cyst's lumen and no germ cell neoplasm (GCN) is present in the adjacent testicular parenchyma.ConclusionAll testicular masses are considered malignant until proven otherwise. It is necessary to do accurate diagnosis for the prevention of unnecessary radical orchiectomy.

A SPECULATED PLEOMORPHIC ADENOMA OF PAROTID TURNS OUT TO BE A SPINDLE CELL LIPOMA

Spindle cell lipoma is a rare benign adipocytic tumour which compromises about 1.5 % of the lipomatous tumour.It is a slow growing tumour most frequently located in upper back and neck with male predominance. Less frequently the tumour may occur in unexpected sites.A 43 year old male patient with history of right sided ,painless, indolent cheek mass. Clinical examination revealed a soft,non tender mass in the parotid region on right side. MRI scan shows lesion arising from tail of right parotid abutting right masseter muscle probably warthin tumor.Fine needle aspiration showed occasional epithelial cells with spindle cells. Case was proceeded with superficial parotidectomy. Grossly there was a well encapsulated mass of size 3.5 cm adherent to the adjacent parotid gland.Histopathology showed mature adipocytes in fibromyxoid stroma with spindle cell suggesting spindle cell lipoma.Spindle cell lipoma,a benign lipomatous tumour usually arises from the shoulder, upper back. These lesions can also arise from atypical sites causing diagnostic challenges. These tumours have to be differentiated from malignant tumours which may require aggressive surgery, while spindle cell lipoma itself is curative by a simple excision.This requires awareness of this entity by both surgeons and pathologists to aim for a proper management .

Buccal Fat Pad: Adjunctive Procedure for Lateral Defect Coverage following Primary Palatoplasty.

The buccal fat flap is an encapsulated mass originating from a specific fat tissue that is easily accessed and richly vascularized. The aim of this study was to report the effect of using the buccal fat flap on the oronasal fistula rate in primary palatoplasty. A case-controlled study of 94 patients who underwent primary cleft palate repair. Patients were divided into two groups: (1) two-flap palatoplasty with buccal fat flap for coverage of lateral hard palate defect and (2) conventional two-flap palatoplasty. The incidence of oronasal fistula and postoperative complications were compared between groups. Multivariate analysis was performed to determine the risk factors of oronasal fistula development. Forty-seven patients in each group demonstrated the same baseline characteristics. The buccal fat group showed a significant lower postoperative oronasal fistula rate (2.13 percent versus 21.28 percent, p = 0.008) and smaller fistula size (2 mm versus 4 mm, p = 0.049). A cleft width wider than 11.5 mm increased the odds ratio of fistula formation by 8.44-fold (p = 0.047), and the use of buccal fat protected against postoperative palatal fistula formation (OR, 0.08, p = 0.019). The use of buccal fat flaps for lateral hard palatal defect coverage in primary palatoplasty can reduce the rate of postoperative palatal fistula, especially in cases of wide palatal cleft. Therapeutic, III.

An interesting cause of a buccal swelling- Long buccal Schwannoma: A case report

Schwannomas are the most common type of benign peripheral nerve sheath tumour and usually occur as a slow-growing, solitary, encapsulated mass. Schwannomas of the oral cavity are rare, with the commonest sites being the tongue, palate and floor of mouth. We present the case of a 28-year-old male patient who presented with a left buccal swelling and pain. Radiological investigation and incisional biopsy led to a diagnosis of a Schwannoma associated with the left long buccal nerve, which was fully excised with no complications.

Endoscopic Management of Maxillary Sinus Schwannoma.

Schwannomas are benign tumors originate from nerve sheath. In this article, the authors aimed to share our experience and review the literature on endonasal endoscopic intervention for a maxillary sinus schwannoma. A 30-year-old Caucasian female patient applying to ophthalmology clinic due to exophthalmos and proptosis in her left eye for the last 6 months. A well-defined mass was detected in left maxillary sinus that was filling and expanding the sinus. Endoscopic biopsy from the patient was reported as ancient schwannoma. The encapsulated mass was completely removed by performing a combined endoscopic medial maxillectomy and Caldwell-Luc procedure under general anesthesia. The authors have been following the patient for 2 years and there was no evidence of recurrence, however, a decrease in the volume of the maxillary sinus occurred, suggesting chronic maxillary atelectasis. In conclusion, schwannoma should be considered in the differential diagnosis of sinonasal masses.
