An unusual giant schwannoma over face diagnosed on FNAC: a case report

Schwannoma is a slow growing benign peripheral nerve sheath tumor arising from schwann cells. It is also known as neurilemmoma. Although it is common in the head and neck region, it rarely exceeds 10 cm in size. Usually Schwannomas are notlarger than 5 to 6 cm in diameter.Large tumors are uncommon and are found in posterior mediastinum or retroperitoneum. We are presenting an unusual giant cell schwannoma over face (cheek) measuring 12×10cmsin size which caused facial deformity to the patient. The tumor was diagnosed on FNAC where cell block was prepared and IHC was done which showed S-100 positivity. This size schwannomaover cheek site has not been reported in the literature as far our knowledge. Therefore this case is unique for its size over face.

Diagnostic dilemma in myoepithelial carcinoma of cheek.

Myoepithelial carcinoma (MC) is a rare neoplasm of the salivary gland generally occurring in the parotid gland and rarely in the minor salivary glands. It poses a diagnostic challenge on fine-needle aspiration (FNA) cytology because it can show different cell types and lack clear features of malignancy. This can lead to a range of differential diagnosis on cytology. The diagnostic difficulty can be compounded if the lesion is present at an unusual site. A 41-year-old male presented with a recurrent swelling on the check since 2 years with a prior history of pleomorphic adenoma (PA) at the same site 8 years back. FNA was performed and a diagnosis of recurrent PA or myoepithelial cell neoplasm was given. Final diagnosis was made on histology and immunohistochemistry studies and reported as MC of minor salivary gland originating within PA. Pathologist should be aware of the occurrence of MC at the sites of the minor salivary glands in the oral cavity and its wide morphologic spectrum to make a confident diagnosis of MC preoperatively.

Multiple Myeloma In Buccal Cheek Mucosa: Report Of A Case And Review Of Literatures

A 65 years old woman presented with indurative buccal swelling without ulceration. The result of the incisional biopsy disclosed as "plasmacytoma", and a series of radiographic and laboratory tests were rendered to find out if it involved multiorgan or not. Based on those studies, we finally diagnosed the disease as multiple myeloma and planned surgical excision followed by systemic chemotherapy.
