Simple cysts of the testis in children: preoperative diagnosis by ultrasound and excision with testicular preservation.

We report on 2 children with simple cysts of the testis who were treated with excision and testicular preservation. To our knowledge both cases represent the first report of conservative surgery for these lesions in children. In 1 case the diagnosis of a simple intratesticular cyst was made by ultrasound. This patient was followed conservatively until enlargement resulted in excision of the cyst with preservation of the gonad. In the other case the diagnosis was made intraoperatively and simple excision of the lesion with testicular sparing was performed. High resolution real-time ultrasound should be performed routinely for all suspected testicular masses in children. Benign testicular tumors are more common than in adults and ultrasound may permit identification of lesions that can be excised locally with testicular preservation. Should the diagnosis of a simple, small intratesticular cyst be made by ultrasound regular followup may be appropriate. Should enlargement occur surgical excision can be done with the possibility of gonadal preservation.
