Spindle Cell Lipoma: Report of a Oral Tongue Lesion with Literature Review / 대한이비인후과학회지

ABSTRACT

Spindle cell lipoma is a relatively rare adipocytic neoplasm that accounts for about 1.5% of adipocytic tumors. This tumor is found in the subcutaneous tissue of the neck, shoulder, or back in most cases. The affected sites of the oral cavity include tongue, buccal mucosa, floor of the mouth, palate, and alveolar ridge. As far as we know, there have been 16 cases of intraoral spindle cell lipoma reported in the literatures, and among them, only seven cases were reported as oral tongue lesion. Spindle cell lipoma is histologically characterized by the presence of an admixture of mature fat cells, uniform spindle cells and short bundles of collagen associated with the spindle cells. In this article, we report, with the review of the literature, a case of spindle cell lipoma occurring in the tongue of a 45-year-old male.
