ACINIC CELL CARCINOMA OF NASAL CAVITY: A RARE SITE FOR SALIVARY GLAND TUMOUR

Salivary gland acinic cell carcinoma.

Solid blue dot tumour: minor salivary gland acinic cell carcinoma.

Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely inv...

Mucoepidermoid carcinoma of a nasal cavity--a rare tumour.

BACKGROUNDS Mucoepidermoid tumours arise from the ductal cells of the salivary glands, most commonly the parotid. The occurrence of these tumours in the mucus glands of the air passages is extremely rare. They are very aggressive tumours with poor prognosis. CASE A case of nasal mucoepidermoid carcinoma with probable origin from the middle turbinate is reported. CONCLUSION Nasal mucoepiderm...

Mammary analogue secretory carcinoma: A rare salivary gland tumour.

Mammary analogue secretory carcinoma (MASC) is a rare and recently described tumour of the salivary glands. MASC has similar histomorphological and immunohistochemical features of secretory carcinoma of the breast. MASC can be mistaken for other salivary gland tumours, especially acinic cell carcinoma. A 28-year-old man was diagnosed with a rare salivary gland tumour in Pretoria, South Africa (...

Cytologic diagnosis of acinic cell carcinoma of minor salivary gland: a distinct rarely described entity

A rare case of acinic cell carcinoma of minor salivary gland with cervical lymph node metastasis in a 50-year-old man is reported and the literature regarding this type of tumor is reviewed. These tumors arise from either an intercalated duct stem cell or the reserve cell of the salivary gland terminal tubule but not from both simultaneously. Rarely these neoplasms arise from more mature acinar...
