Figure

• 

  Fig. 1 (A) Asymmetric, multiple, grouped, irregular, flat, dark brownish papules and macules on the inguinal area. (B) Dermoscopic features showing a patchy reticulated network.

• 

  Fig. 2 (A) There was elongation of rete ridges and increase in the number of junctional melanocytes, arranged in a nest. In the dermoepidermal junction, nests of nevus cells were profused on the tips and sides of elongated rete ridges. There were also scattered single cells in a lentiginous array without continuous proliferations. (B) Several melanocytes contained abnormally large nuclei, and the nuclei had irregular contours (arrows) (H&E; A: ×40, B: ×400).
