Case 3.

A. Dermoscopic image of a 7-mm brown-black lesion (group A) on the abdomen of a 60 year-old male shows a multi-component pattern with peripheral network and central blue-white structures. The lesion was clinically and dermoscopically suspicious for melanoma. B. Basic RCM image (0.5mm × 0.5mm) at the dermo-epidermal junction and basal layer displays a disarranged pattern with bright dendritic and roundish nucleated cells (→) in medium density. C.: Histopathologic analysis (H&E; original magnification ×100) reveals a compound nevus, characterized by a proliferation of melanocytes as solitary units or small and large nests situated at the dermoepidermal junction and in the papillary dermis. The melanocytes have small oval monomorphous nuclei and scant cytoplasm. D. Staining for Melan-A reveals numerous melanocytes in the basal and spinous layers.
