Spindle cell lipoma of the buccal mucosa: Uncommon finding in an older adult.

Objective: This article reports a case of a longstanding, slowly enlarging intraoral spindle cell lipoma (SCL) that had become increasingly painful during mastication.

Background: The SCL represents an uncommon variant of the conventional lipoma. There is limited information regarding this lesion in the gerodontologic literature.

Methods: A 68-year-old patient underwent an excisional biopsy of a 9-mm slightly yellow papule along the buccal mucosa.

Results: The surgical specimen was composed of mature adipocytes with abundant spindle cell populations and was diagnosed as a SCL.

Conclusions: Timely removal of the SCL may reduce the incidence of clinical and surgical complications, particularly in older adults. The management of a SCL is complete excision, and recurrence is rare. Lesions must be carefully distinguished microscopically from its malignant counterpart, the spindle cell liposarcoma.
