Penile epidermal inclusion cyst mimicking ectopic testis mass: A case report.

Epidermal inclusion cyst is a benign lesion that can originate in all parts of the human body. However, the penile location is quite rare. We reported a 24-years old man with a painless, soft, progressive-growing mass at the distal part of the penis with a history of ectopic undescended testis. Complete resection was performed, and further histopathologic study revealed an epidermal inclusion cyst of the penis. This report would like to present a rare case of a penile epidermal inclusion cyst mimicking an ectopic testis mass at our institution.
