[Unusual localization of granulosa cell tumor].
OBJECTIVE
To present a case of granular cell tumor with an uncommon localization.


METHODS
A 38-year-old patient presented with a painless nodule 10 mm in diameter on the scrotum that he had noted two years earlier.


RESULTS
The tumor was surgically excised. Pathological analysis demonstrated a granular cell tumor that was strongly positive for protein S-100 and negative for cytokeratin AE1-AE3 and CEA.


CONCLUSIONS
Granular cell tumors are very frequent in the head and neck, but rare in the genitourinary region and are asymptomatic. Histological diagnosis is simple but should be confirmed by protein S-100 staining, which is positive in all cases. Treatment is by simple excision of the lesion. Tumor recurrence and metastasis have been reported, therefore follow-up is necessary.
