case_images: A, B, C: Brown macules on the lateral aspect of the glans
  and prepuce of the penis, almost symmetrical on both sides of the
  coronal sulcus

case_images: Upon retraction of the foreskin, the lesions appeared as a mirrored image (Figure 1).
case_images: Dermoscopy of the macules revealed melanocytic lesions in a compound
  pattern. In the periphery, there was fine pigment network and in the
  center, dark globules of different sizes. A: lesion on the
  glans; B: lesion on the prepuce

case_images: The lesions were separated by a thin streak of non-pigmented skin on the prepuce and it was possible to observe a few globules on the coronal sulcus (Figure 2).
case_images: Photomicroscopy of the glans skin. A: Proliferation of
  densely pigmented melanocytes along the dermal-epidermal junction and
  papillary dermis (Hematoxylin & eosin, X100); B:
  Proliferation of densely pigmented melanocytes along the
  dermal-epidermal junction and forming nests in the papillary dermis
  (Hematoxylin & eosin, X400); C: Melanocytes with
  evident nuclei (arrows) (Hematoxylin & eosin, X400)

case_images: Histopathology of both lesions revealed a proliferation of densely pigmented melanocytes with abundant cytoplasm, along the dermal-epidermal junction and forming nests in the papillary dermis suggestive of a compound melanocytic nevus (Figure 3).
