          Abstract

          Presentamos un caso clínico de diagnóstico prenatal de una masa testicular. Tras el nacimiento, se realizó la exéresis del tumor y el análisis anatomopatológico determinó que se trataba de un tumor de células de la granulosa juvenil. Los tumores testiculares son raros y deben considerarse en el diagnóstico diferencial de las masas escrotales en los neonatos. El tumor de células de la granulosa juvenil es una entidad clínico-patológica poco frecuente, que representa el 5% de los tumores testiculares prepuberales. Se considera una neoplasia benigna y la orquiectomía es una técnica quirúrgica curativa.

          Translated abstract

          We report a case of a prenatally diagnosed testis tumor. After delivery, it was decided to perform right radical orchiectomy which was subsequently diagnosed as a juvenile granulosa cell tumor. Neonatal testicular tumors are rare and should be considered in the differential diagnosis of newborn scrotal masses. Juvenile granulosa cell tumor is a rare benign neoplasm of the testicular stroma that accounts for 5% of all prepuberal testis tumors. As a benign neoplasm, orchiectomy is sufficient for treatment.

          Prenatal diagnosis of juvenile granulosa cell tumor of the testis.

          Juvenile granulosa cell tumor is a rare benign neoplasm of the testicular stroma that accounts for 1-5% of all prepubertal testis tumors [Metcalfe PD, Farivar-Mohseni H, Farhat W, McLorie G, Khoury A, Bagli DJ. Pediatric testicular tumors: contemporary incidence and efficacy of testicular preserving surgery. J Urol 2003;170:2412-2416; Ross JH, Rybicki L, Kay R. Clinical behavior and a contemporary management algorithm for prepubertal testis tumors: a summary of the prepubertal testis tumor registry. J Urol 2002;168:1675-1679]. A prior case series retrospectively identified a cystic testis tumor on prenatal ultrasound images which was subsequently diagnosed as a juvenile granulosa cell tumor [Bryan DE, Cain MP, Casale AJ. Juvenile granulosa-theca cell (sex cord-stromal) tumor of the infant testis. J Urol 2003;169:1497-1498]. We report a case of a prenatally diagnosed testis tumor which was subsequently diagnosed as a juvenile granulosa cell tumor.

            Congenital juvenile granulosa cell tumor of the testis in newborns.

            Granulosa cell tumor of the testis is a rare intermediate stromal cell tumor that can be distinguished in the adult and juvenile type. The juvenile type is the most common reason for scrotal swelling in newborns under the age of six months. Less than fifty cases of this disease entity have been reported in the literature.
