Intrascrotal adenomatoid tumors and their ultrasound findings.

Adenomatoid tumors are regarded as uncommon neoplasms of the paratesticular tissues, probably of mesothelial origin, and the majority of cases reported have involved the epididymis. Ultrasonography is the method of choice for imaging scrotal pathology, but there are very few data on ultrasound findings in cases of adenomatoid tumors. We report our experience and ultrasound findings regarding 8 intrascrotal adenomatoid tumors--3 cases of a testicular tunica albuginea tumor and 5 cases of epididymal origin. Ultrasonography is recommended as the preoperative imaging method for excluding the possibility of a cystic lesion and for determining the location of the tumor. Local excision is regarded as the treatment of choice. The clinical course of all these tumors was benign, without recurrences.
