Infantile testicular cyst: diagnosis and conservative surgical management.

The authors report on a 5-month-old boy who had a simple cyst of the testis and was treated by testis-sparing cyst excision. Preoperative ultrasonography was diagnostic of a simple cyst. The patient has been without recurrence for over 2 years, and examinations have shown a normal size testis. A literature review showed only four cases of infantile simple cysts of the testis, only one of which was diagnosed preoperatively and treated by cyst excision. Four of the 5 reported cases (including ours) were diagnosed at 5 months of age. We recommend organ-preserving cyst excision in males under 1 year of age who are found to have an intratesticular lesion that is a simple cyst by ultrasound criteria.
