A 65-year-old man consulted for a non healing ulceration on his right heel.This ulceration had been occuring on a pigmented lesion present for 5 years. The clinical diagnosis of acral lentiginous melanoma was quite evident on examination.
Melanoma on the palms and soles have a distinct pigment network called parallel ridge pattern. The ridges are centered by white dots which are the openings of eccrine sweat ducts.
