Diagnosis

Juvenile Granulosa Cell Tumor of the Testicle

Clinical Notes

Alpha fetoprotein – 25707 ng/mL

Findings

US – Testicular tissue is replaced by cystic mass with thick hyperemic septae. Hydrocele is present.

Pathology – Bivalved specimen showing a yellowish multicystic mass with thick septae and no recognizable testicular tissue.

Discussion

Granulosa cell tumor is a sex-cord stromal neoplasm with two subtypes – adult and juvenile. Juvenile granulosa cell tumor is a very rare testicular lesion usually diagnosed during infancy by the presence of a scrotal mass. In 20% of cases, anomalies of the Y chromosome and/or ambiguous genitalia are present. Imaging reveals a well-defined, large multicystic intratesticular mass. Differential diagnosis includes germ cell neoplasm and testicular torsion. Orchiectomy is the only treatment necessary.
