Abstract
Basal cell adenoma is a rare epithelial neoplasm of the salivary glands, with a predilection for the parotid gland and uncommon in minor salivary glands. A 68-year-old Black man was referred to a dental clinic for evaluation of nodular lesions in the oral cavity. On physical examination, a 40-mm increase in volume was observed in the region of the left upper lip, which was purplish in color, without painful symptoms on palpation and with an approximate evolution of 1 year. An incisional biopsy was performed and the specimen was sent for microscopic analysis. In the histopathologic exam it was possible to verify slides of uniform aspect with a predominance of basaloid cells, myxochondroid component, and different morphologic patterns. Based on clinical and histologic findings, the final diagnosis was basal cell adenoma. As treatment, excisional biopsy with local anesthesia was chosen. After 2 years of follow-up, the patient showed no signs of recurrence.
