Abstract

Fibroepithelioma of Pinkus is generally accepted as a low-risk variant of basal cell carcinoma. A 66-year-old man was presented with a solitary dark red nodule with superficial erosion on his right groin. It tended to bleed, but was otherwise asymptomatic. Histopathologically, the tumor was composed of long, thin, branching and anastomosing strands of basaloid cells, which extends from the epidermis into the fibromucinous stroma. Basaloid tumor cells were palisaded at the periphery of the strands, and small buds were seen projecting from the epithelial strands. Significant amounts of melanin pigment were deposited in the papillary and reticular dermis, and the stroma between the tumor cords and also inside the tumor cells. The lesion was completely excised with clear margin. We report a case of pigmented fibroepithelioma of Pinkus with review of the literature in this communication.
