Abstract:
Various epidermal changes overlying a dermatofibroma can be induced through the proliferation of pluripotential epidermal cells by the stimulation of mesenchymal factors. The authors report a case of dermatofibroma in a 55-year-old male who had a reddish brown, asymptomatic nodule of 5 years duration on his left forearm. The biopsy specimen revealed a dermatofibroma of cellular type associated with epidermal changes: (1) acanthosis; (2) elongation of rete ridges; (3) thin interlacing epidermal strands with increased pigmentation resembling seborrheic keratosis or fibroepithelioma; (4) immature hair follicles and sebaceous lobules; (5) hair germ like buddings; (6) superficial basal cell epithelioma-like proliferations.
