Eccentric peripheral hyperpigmentation is frequently found in MM. Atipical naevi with this type of pigmentation should be regarded as the most relevant simulators of MM and need excision or close monitoring.

A. Atypical naevus with reticular pattern, atypical pigment network and eccentric hyperpigmentation on the inferior area

B. Atypical naevus with eccentric hypopigmentation on the left area suggestive of regression. This lesion needs excision to rule out MM. Histology was reported as compound naevus with mild architectural and citological atypia
