Salivary gland-type basal cell adenocarcinoma of presumed bartholin's gland origin: a case report.

Salivary gland-type carcinomas arising in Bartholin's gland are rare neoplasms. We report the case of a 75-year-old female who presented with a vulvar tumor with morphological and immunophenotypical features identical to those of salivary gland basal cell adenocarcinomas. We believe that the tumor was most likely of Bartholin's gland origin, although no Bartholin's gland tissue was found adjacent to the neoplasm. This type of malignancy with myoepithelial differentiation has not been previously reported to arise in the Bartholin's gland.
