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.
