Adult Type Testicular Granulosa Cell Tumor: Case Report and Review of the Literature

Abstract

Granulosa cell tumors represent a special group of the so-called sex cord-stromal tumors of the gonads, and are divided into 2 histological types: adult and juvenile. Adult type testicular granulosa cell tumor is a rare neoplasia: 22 cases of this testicular tumor only have been described in literature so far. They are often discovered accidentally and exhibit no endocrine-related symptoms. We report a case of adult type granulosa cell tumor in a 45-year-old man likely affected by a 15-year-old painless tumor with increased right testicular size; he underwent radical orchiectomy. This case and a review of the literature indicate that this kind of tumor is a rare, slow-growing neoplasm. Since distant metastases may occur late in the clinical course, long term follow-up of these patients is recommended.
