Abstract

Basal cell adenoma is a rare type of salivary gland tumor. It is benign and most frequently occurs in the parotid gland; it very rarely occurs in the minor salivary gland. We report a rare case of basal cell adenoma of the upper lip. A 75-year-old woman was referred to our hospital complaining of swelling of her upper lip. She had noticed a swelling, movable, painless, elastic-hard mass measuring about 10mm in her upper lip 5 years earlier which had been left untreated. Intraoral examination revealed a marked small swelling without inflammatory symptoms in the center of the upper lip. The lesion was a well-defined submucosal mass. The size of the lesion with high signal was about 5mm and showed mobility. We performed image examination, including magnetic resonance imaging and ultrasonography. The tumor was resected with adequate margin with its surrounding tissue. Histological and immunohistochemical studies were performed, and a diagnosis of basal cell adenoma was made. There has been no sign of recurrence or metastasis for 20 months postoperatively. We consider that careful follow-up remains necessary.
