Minor salivary gland intraductal mucoepidermoid carcinoma: a case report.

We describe a case of an intraductal mucoepidermoid carcinoma arising from a minor salivary gland of the oral cavity. This is a rare presentation, and our literature review identified only a single previously documented case. To the best of our knowledge, this is the first reported case to be verified by immunohistochemistry demonstrating myoepithelial or basal cells around all the neoplastic units.

Sclerosing polycystic adenosis of the parotid gland.

Sclerosing polycystic adenosis of the major salivary glands is rare and can simulate a slow growing tumour. It is pseudoencapsulated and includes tubuloacinar adenosis with dilated ducts, apocrine metaplasia, epithelial hyperplasia, and cystic changes associated with fibrosis. The histological appearance of the lesion is similar to that of fibrocystic disease of the breast.

Isolated involvement of the gallbladder by Crohn's disease manifesting as acute cholecystitis.

A 79-year-old female presented with acute cholecystitis. Having recovered on conservative management, elective laparoscopic cholecystectomy was performed. The diagnosis of Crohn's disease of the gallbladder was a histopathological surprise.
