Adult paratesticular tumors: report of two cases.
Paratesticular tumors are uncommon tumors, most being found incidentally at autopsy. The most common benign paratesticular tumor is the adenomatoid tumor. A somewhat less frequent benign paratesticular tumor, papillary cystadenoma, accounts for approximately 33 percent of all the primary epididymal tumors and is frequently seen in patients with Von Hippel-Lindau disease. Malignant tumors are rare. Of these, rhabdomyosarcoma is the most frequent. Seen almost exclusively in the pediatric population, paratesticular rhabdomyosarcomas account for 7 percent of childhood rhabdomyosarcomas. We describe two cases of paratesticular tumors in adults: a papillary cystadenoma of the epididymis in a 72-year old male, and an incidental rhabdomyosarcoma in a 49-year old male.
