Abstract
- Dermatofibroma is a common benign fibrohistiocytic tumor which may present with a variety of pathological variants. Combined dermatofibromas are defined as dermatofibromas which show two or more histological variants in a single lesion. We herein report an unusual case of dermatofibroma in a 39-year-old man who presented with a solitary asymptomatic black-colored nodule on his right thigh, which showed histological features of aneurysmal and atypical variants simultaneously. Histologically, it showed cleft-like vascular spaces with hemorrhaging and focal cellular atypia in the background of typical dermatofibroma.
