Abstract

Testicular granulosa cell tumor(GCT) is a rare neoplasm. We report here on an incidentally discovered testicular granulosa cell tumor in a 36-year-old man. The serum tumor markers were within the normal limits. The ultrasonographic findings revealed a mass with a heterogenous hypoechoic echotexture, including multiple variable sized cystic components. The histology on the orchiectomy specimen demonstrated a gonadal stromal tumor with granulosa cell features. Testicular granulosa cell tumor of the adult type is a very rare tumor, and there have been several isolated case reports and small serial studies described in the literature.

Figure

• 

  Fig. 1. Ultrasonography shows a mass with heterogeneous hypoechoic echotexture and multiple variable sized cysts in mass.

• 

  Fig. 2. The cut surface revealed a huge gray brown to yellow solid tumor that involved almost the whole testis, with multifocal cystic changes and hemorrhages.

• 

  Fig. 3. The tumor consisted of a homogeneous population of basophilic, bipolar, cells with angular grooved nuclei. Call-Exner bodies imparting a microfollicular pattern were focally present throughout the tumor (x200).
