A case of sebaceous lymphadenoma occurring in the lip of a 73-year-old female is described. The patient had noticed a painless mass in the region of her upper lip for a year. The surgically removed tumor, measuring about 10 mm in diameter, was located just beneath the lip mucosa, expanding into the submucosal and muscle layer. Histologically, the tumor was well encapsulated and consisted of scattered round-shaped islands of small squamous epithelial cells with focal but apparent sebaceous differentiation in a background of lymphoid stroma. This is the first case report of sebaceous lymphadenoma of minor salivary gland origin.
