  • Fig. 1 (A) Brown and black linear plaques on the scrotum and perianal region. Dermoscopic findings of the dark blue to black plaque on the (B) scrotum and (C) perianal region.

  • Fig. 2 Histopathologic findings showing a cystic cavity (A: H&E, ×40) that is lined by cuboidal epithelium containing melanin pigments (H&E, B: ×100, C: ×200) and stratified squamous epithelium (D: H&E, ×100). Immunohistochemical staining demonstrates diffuse staining of (E) c-kit (×40), (F) S-100 (×200), (G) Fontana-Masson (×200), and (H) 8 Melan-A staining (×200).
