Abstract
|
|
|
Purpose: Dermatofibroma is a common benign dermal tumor characterized by a proliferation of fibroblast-like spindle cells. It is commonly localized on the skin of extremities and presents as a slow growing solitary nodule. To our knowledge, the occurrence of dermatofibroma in the oral cavity is rare. Herein, we report a rare case of dermatofibroma on the lower lip.
Methods: A 60-year-old woman presented with a slow growing mass that measured 1 × 0.8 cm in diameter on the lower lip. The mass was surgically excised with clear margins.
Results: Histologically, the mass was characterized by a nodular tumor composed of collagen bundles, fibroblasts, and histiocytes, which were findings consistent with dermatofibroma. The postoperative course was uneventful without any complications.
Conclusion: When evaluating nodular tumors of the oral area, dermatofibroma should be considered in the differential diagnosis.
