Abstract
Intra-oral sebaceous adenoma (SA) is a rare benign tumor accounting for 0.1% of all salivary gland neoplasms consisting of sebaceous epithelium in a fibrous stroma. A 50-year-old female was referred by her dentist for treatment of an oral lesion in the right buccal mucosa and retromolar trigone. Clinically, a nodule asymptomatic was observed, 1.5 cm, sessile base, rose-colored with the central region yellowish and areas of telangiectasia, with 6 months’ of evolution. The patient also presented Fordyce granules on buccal mucosa, bilaterally. Clinical diagnosis of lipoma was made. After excisional biopsy, the histologic sections revealed a tumor composed of sebaceous cell nests and dilated salivary ducts with areas of squamous differentiation and minimal atypia, enclosed in a fibrous stroma. Minor salivary glands with usual aspects were observed deeply. Final diagnosis was SA, and the patient follow-up is being conducted.
