[Paratesticular fibrosarcoma. A rare malign neoplasm].

Hereby we wish to present the clinical and pathological results of a rare paratesticular sarcome of the spermatic cord. This tumor was a fibrosarcoma in a 55 year old male that started in a most unusual way and developed very quickly. We practised a radical orquitectomy with inguinal ligation of the pedicule without post-operatory therapy. After a 5 year follow up, there is no trace of clinical or radiological recurrence in the region or metastasis. We consider radical surgery to be the only therapeutic alternative, even for cases of fast developing, being in our case a good pronostic.
