| Title | adenomatoid tumor of the scrotum |
| Text | As in real estate as well as radiology, location of a lesion is of prime importance. In evaluating an intrascrotal lesion/mass, one must decide whether the abnormality is intratesticular or extratesticular/paratesticular, as the differential diagnosis is quite different for these locations.
Extratesticular mass differential includes: inguinal hernia; inflammatory mass such as infection, sarcoidosis; benign neoplastic processes such as adenomatoid tumor, epidermoid inclusion cyst; malignant processes such as soft tissue sarcomas, mesothelioma of the tunica, lymphoma, and metastatic disease. This case is a surgically proven adenomatoid tumor. This is one of the more common extratesticular lesions. It is a benign, slow-growing mesothelial neoplasm, presenting usually during the second to fourth decade of life. Usually it is a well-defined, extratesticular, iso- to hyper-echoic (relative to testis) solid mass. Usually they are within the epididymis, but rarely can be located in the tunica albuginea (as in this case) or within the spermatic cord. |
