Accessory scrotum attached to a perineal lipoma in an adult male.

Accessory scrotum is a condition in which a scrotum is located in the perineal region, in addition to the presence of normally located primary scrotum, testes and penis. The condition is extremely rare and the majority of reported cases have been diagnosed in infants. Herein, we present a case of accessory scrotum attached to a perineal lipoma in a 40-year-old man. The perineal mass was present at birth and grew very slowly over the years. There were no other congenital abnormalities or problems related to this anomaly. The case was easily managed by complete excision of the accessory scrotum and perineal lipoma. Gross and microscopic examination of the surgical specimen revealed an accessory scrotum attached to an encapsulated perineal lipoma. The present case demonstrates an adult prognosis of a patient born with this type of abnormality. To our knowledge, it is the first case of its kind to be reported in the literature.
