A 6-year-old boy was found to have a nodule in the right testicle.

This is a rare benign tumor in the testis. The tumor is more common in pre-pubertal age and the great majority of cases are identified in children under one year of age.  By immunohistochemistry, these tumors are positive for inhibin,
