Basal cell adenoma (BCA) is a rare benign tumor of salivary gland origin characterized by amonomorphic basaloid epithelial population, comprising 1% to 3% of salivary gland tumors. The major salivary gland of the parotid is the primary site of involvement (75%), although it may rarely occur in the submandibular gland. Minor salivary glands may also harbor the tumor, most commonly the upper lip (20%) followed by the lower lip, buccal mucosa, and palate. Standard treatment is local excision or enucleation with a 6.7% overall recurrence rate and a 25% recurrence rate in the membranous subtype, attributed to its multinodularity. Complete removal with margin control is important, as recurrences have been attributed to incomplete excision.We report the first case of BCA of the upper lip treatedwithMohsmicrographic surgery.
