Basal cell adenocarcinoma of the minor salivary gland - A rare case report involving the upper lip.

Minor salivary gland neoplasms constitute up to approximately 25% of all salivary gland tumors. The incidence of malignancy of these tumors is slightly greater than half. Basal cell adenocarcinoma (BCAC) is a rare salivary gland malignancy that occurs most commonly in the parotid gland. In this report, we describe a case of an older woman presenting with BCAC of the upper lip arising from the minor salivary gland.
