Simple testicular cyst: a rare cause of scrotal swelling in infancy.

Abstract

A simple testicular cyst is a rare cause of scrotal swelling in infancy. Only 10 cases have been reported in children less than two years of age in the English literature. Pathogenesis of the lesion is unclear. Preoperative diagnosis is possible using ultrasonography (US). Testis-sparing surgery with simple enucleation of the cyst has a favorable outcome. We report two patients with a simple testicular cyst, who were 9 and 8 months of age. The first case was referred with a presumptive diagnosis of hydrocele, and the second infant was admitted with a history of testicular swelling. Ultrasonography provided accurate preoperative diagnosis in both of the cases. The patients were successfully treated with testis-sparing surgery with outstanding long-term results. This unusual lesion of infancy should be considered in the differential diagnosis of a scrotal mass.
