A Case of Dermatofibroma of the Upper Lip

ABSTRACT

Dermatofibroma (DF) is a common benign mesenchymal tumor composed of fibroblastic and histiocytic cells. It occurs anywhere on the body surface but has a propensity for the extremities. To our knowledge, DF arising in the oral cavity, especially on the lip, is quite rare. DFs of the head and neck region have been known to be most often of the cellular type and frequently recur, so a wider initial excision is recommended. Herein we report a case of DF in a 41-year-old female who presented with a deep-seated nodule on her upper lip.
