Granular cell tumor of the penis in a 5-year-old boy.

We evaluate a rare case of a 5-year-old boy with granular cell tumor of the penis, located on the coronal margin. We discuss the anatomic distribution of granular cell tumors, noting the marked female predominance of genital involvement and reviewing the distribution of granular cell tumors by site in a pediatric series. We also discuss clinical implications, management, and histogenesis.
