Cholesterotic fibrous histiocytoma is a particularly rare variant of dermatofibroma that is distinguished histopathologically by the presence of prominent cholesterol deposits within the lesion. We report the case of a 54-year-old male with poorly controlled hyperlipidemia who presented with a firm violaceous papule on the right shin, diagnosed as a cholesterotic fibrous histiocytoma. We also review and summarize the existing literature on this uncommon entity.
