Abstract

Verrucous-keratotic melanoma is a variant of melanoma that may be confused with benign lesions. We report a case of a 58-year-old man with a verrucous-keratotic lesion on his left leg. The lesion resulted a verrucous melanoma level IV of Clark, 10.35 mm in thickness according to Breslow. Verrucous-keratotic melanomas are rarely mentioned today. They do not seem to have a sex and site predilection and they are clinically characterized by keratotic, exophytic and greyish surface. They have a tough, fleshy and not friable consistency. The main clinical differential diagnoses are with seborrheic keratosis and benign nevi. Histologically most of verrucous-keratotic melanomas resemble to the superficial spreading and acral lentiginous types of melanomas with verrucous surface. The prognosis of the verrucous-keratotic melanomas do not seem to be significantly different from other melanomas, but a long term follow-up is required for assess their true biologic behaviour.
