Glomus tumor of the upper lip: A case report

A glomus tumor is a mesenchymal neoplasm originating in the modified smooth muscle cells of glomus bodies, with rare presentations in the oral cavity. Clinically, glomus tumors present as a purple to red vascular nodule measuring 1–1.5 cm. They usually appear in adult patients aged 40–70 years, with no gender predilection. Glomus tumors are rare in the head and neck region, and the lips constitute the most-reported location of oral glomus tumors, followed by the hard palate, tongue, buccal mucosa, and gingiva. The exact etiopathogenesis of glomus tumors remains poorly understood. We present a case of an 80-year-old man with an 8-year history of a nontender soft lump on the upper lip. Total resection of the tumor was performed, and the histopathological finding was consistent with that of a glomus tumor.
