Figure

  Fig. 1 Spitz nevus on the perianal area: an erythematous pedunculated nodule with tiny black pigmentation anterior to the anal orifice.

• 

  Fig. 2 Histological examination showed (A) numerous nests of cells in the entire dermis (H&E, ×40). On the tip of the rete ridges (B), some proliferation of nevus cells and melanocytes are visible (H&E, ×40). In the superficial dermis (C) and deep dermis (D), the cell nests are composed of epithelioid nevocytes that have a large cell size, abundant cytoplasm, cleft around cells, and prominent nucleoli (H&E, ×200). There was no atypical mitosis or pagetoid spreading.
