Prepubertal testicular tumors: frequently overlooked

Prepubertal testicular tumors: frequently overlooked

Journal of Pediatric Urology 3(6): 480-483

Prepubertal testicular tumors are fundamentally distinct from their adult counterparts. We reviewed our 10-year, two-institution experience with respect to diagnosis and treatment. A retrospective review was performed of all testicular tumors diagnosed between 1996 and 2006 in males younger than 14 years. We analyzed clinical characteristics, diagnostic procedures, treatment methods, histopathologic findings and outcome. Of 15 primary testicular tumors, eight (53%) were germ-cell tumors (three teratomas, two yolk sac tumors, one seminoma, one embryonic carcinoma and one choriocarcinoma), four (27%) tumor-like lesions (epidermoid cysts), two (13%) gonadal stromal tumors (a Leydig and a Sertoli cell tumor), and one (7%) gonadoblastoma with gonadal dysgenesis. All boys were presented with a painless scrotal mass and four (27%) of them with elevated tumor markers. Ten cases (66%) were misdiagnosed by urologists preoperatively and presented for treatment of congenital or acquired scrotal disorders. Twelve children (80%) were treated with radical orchiectomy and three (20%) with a testis-sparing procedure. At a mean 4-year follow-up no patient has presented with recurrent tumor in the residual or contralateral testicle. Postoperative physical examination and scrotal ultrasound were obtained in 14 patients at a median follow-up of 48.2 months, and there was no evidence of tumor progression. One boy with a choriocarcinoma (stage IV) died due to distant metastases. Benign teratoma and epidermoid cysts were the most common prepubertal testicular tumors. Any suspicion of a testicular tumor warrants an inguinal approach to prevent scrotal violation of the tumor. Our limited experience with testis-sparing procedures supports the current trends that organ-confined surgery should be performed for benign lesions such as teratoma, Leydig cell tumor and epidermoid cysts based on frozen biopsy findings.
