An Unusual Cause of Infantile Gynecomastia

Abstract

Prepubertal testicular masses are relatively rare. Sertoli cell tumors account for 2% of prepubertal testicular tumors and very few have occurred in the first decade of life. Gynecomastia can be seen in approximately 5% of patients with testicular mass. We present an 8-month-old boy admitted with bilateral gynecomastia and unilateral testicular mass.
