Abstract
- Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering the peripheral nerves. Common locations include the head, neck, mediastinum, and retroperitoneum. These tumors are usually asymptomatic until they become large and compress the surrounding tissues. Most schwannomas occur during the third and fourth decades of life, with an equal gender distribution. We present the case of a schwannoma that originated in the scrotum.

FIG. 1 (A) Gray scale ultrasonography of the left scrotum revealed a well-circumscribed heterogeneous scrotal mass (M) that was well separated from the epididymis (E) and testis (T). (B) The mass involved the scrotal wall and was isoechoic in echotexture. Color Doppler demonstrated mild increased vascularity in the extratesticular mass lesion.
FIG. 2 Gross photograph shows an oblong, firm scrotal mass. The cut surface was whitish and multinodular with a lobulated and glistening appearance with central yellow-brown areas.
FIG. 3 Low-power view of a section of the tumor shows alternation of hypercellular Antoni A and hypocellular Antoni B areas (H&E, ×10).
FIG. 4 High-power view of a tumor section shows Antoni A area composed of spindle cells often arranged in a palisading pattern or in an organoid pattern representing Verocay bodies and hypocellular Antoni B area (H&E, ×40).
