An Intrascrotal Extratesticular Mass

Yoganand Gundamraj, Margery Howard, Edward Rosenthal, Sinai Samaritan Medical Center, Milwaukee, WI

A 35 year old African American male with von Recklinghausen's disease presented with a left testicular mass. The patient has noticed a small scrotal swelling several years ago which remained unchanged. The swelling had increase over the past 2 months and now is associated with pain. He did not complain of any urinary problems. Physical examination revealed multiple non tender soft nodules with café au lait spots throughout. Examination of the scrotum revealed a 3x7 cms oval shaped tender firm mobile mass located in superior anterior aspect of left testicle. Ultrasound showed a solid mass close to the left testes but unattached to it. This mass was surgically resected via an inguinal approach. Histopathology showed an anaplastic glandular malignant schwannoma originating from a focus of residual neurofibroma lesion.

Discussion: Malignant schwannomas are highly malignant rare lesions. Malignant degeneration of neurofibromas has been described but there is only one case report of schwannoma arising from a scrotal neurofibroma.
