A case of basal cell adenocarcinoma of the palate

Abstract

Basal cell adenocarcinoma is a rare type of malignant salivary gland tumor found most often in the parotid gland. We present a case of basal cell adenocarcinoma of the minor salivary glands in the palate. Histologically, tumor islands were composed of relatively uniform, monotonous cells, and the tumor invaded blood and lymphatic vessels. Immunohistochemically, the tumor cells showed positiveimmunoreactivities with cytokeratin AE 1, epithelial membrane antigen, vimentin, and S-100 protein.
