ABSTRACT

Observation:

A 54-year-old woman was presented with a heterogenously pigmented, slightly elevated lesion on the leg. Dermatoscopy revealed atypical pigment network and pseudopots, whitish veil on the center on a pinkish background. Histopathological diagnosis of the totally excised lesion was melanoma in situ on preexisting dermal melanocytic nevus. The occurrence of multipl dermatoscopic findings of an atypical lesion led us for suspicion of melanoma in this case. Therefore, the importance of dermatoscopy for early diagnosis of melanoma on a preexisting benign nevus was emphasized by the agency of the presented case.
