An 18-year-old boy presented with an asymptomatic, occasionally bleeding, flesh colored growth on his left leg for 10 years. A well-defined, 3 cm × 4 cm, flesh colored, sessile, soft, mobile, non-tender, nodule was noted on the left calf. The nodule protruded slightly from a shallow cup-shaped depression and had a slightly raised hyperpigmented rim. There was scaling and crusting of the surrounding skin because of repeated cleaning of the growth and surrounding area with undiluted 10% povidone-iodine solution [Figure - 1]. There were no other abnormalities on mucocutaneous examination.

Histopathological examination revealed a well circumscribed tumor arising from the epidermis in the form of broad and anastomosing columns of basaloid cells along with necrosis en masse and a fibrovascular stroma [Figure - 2]. Medium power revealed small and uniform oval cells with a central nucleus, some ductal lumina and a fibrovascular core [Figure - 3].
