Congenital mucus retention cyst of penis presenting as skin papilloma.

摘要

A 20-year-old boy presented with an abnormal protrusion of tissue from the penile skin that had been present since birth.. It was painless and caused no problems, except for cosmetic disfigurement On examination, it was a 1-cm, soft, mushroom-shaped papilloma arising from the dorsum of the shaft of the penis near to the root of the penis (Fig. 1). Retrograde urethrography and cystoscopy was done to rule out any communication with the urethra. It was excised with a 1-cm margin of penile skin around it. Histopathologic examination of the specimen revealed hyperplasia of squamous epithelium with koilocytosis, and the underlying tissue had a mucus retention cyst (Fig. 2).
