Superficial spreading melanoma

A 60-year-old man consulted for a changing of color of one of his nevi on his back. The upper part of this nevus turned dark brown a few months before.

On the upper part of the lesion, dermoscopy revealed an atypical reticular pattern, asymmetric irregular globules and a blotch.

On the lower part of the lesion, there was an homogeneous non pigmented pattern with some comma vessels in favor of a dermal nevus.

The tumor was excised and pathology revealed a superficial spreading melanoma developed on a pre-existing dermal nevus.
