Figure 1.
A) a red mulberry-shaped nodule on the lower abdomen to the base of the penis (30 mm × 25 mm × 15 mm) with some red papules on the margin; B) a dermoscopic image of the penile nodule showing branched and/or partially reticular linear vessels in a pale red structureless area.

Figure 2. A) histopathological features of the primary tumor. The tumor nests show diffuse infiltration from the upper dermis to the subcutaneous tissue (hematoxylin-eosin, original magnification ×40); B) tumor nests of varying sizes are seen (hematoxylineosin, ×200); C) the tumor cells are small- to medium-sized with abundant and pale eosinophilic cytoplasm, round-to-oval nuclei, and a “salt-and-pepper” chromatin pattern. Few nuclear atypia and mitotic figures are observed (hematoxylin-eosin, ×400); D) a tumor mass floating in abundant mucus is observed in part of the tumor (<10%) (hematoxylin-eosin, ×200); E) tumor cells displayed a trabecular growth pattern with abundant extracellular mucin deposition in the resected lymph node (hematoxylineosin, ×200).
