Neoplastic and non-neoplastic proliferations of the testicular collecting s
ystem may be a source of diagnostic difficulty as they are rarely encounter
ed and may have an appearance that leads to confusion with lesions arising
in adjacent structures. The rete testis and epididymis are the 2 sites that
are most likely to give rise to this unusual group of lesions, This articl
e principally, although not exclusively, deals with those lesions that prod
uce an intrascrotal mass. These include benign acquired or developmental cy
sts such as cystic dysgenesis of the rete testis or acquired cystic transfo
rmation of the rete testis, non-neoplastic epithelial proliferations such a
s adenomatous hyperplasia of the rete testis or cribriform hyperplasia of t
he epididymis, and benign or malignant neoplasms, Rate testis cystadenoma,
including the sertoliform variant, and papillary cystadenoma of the epididy
mis are examples of benign tumors of the testicular collecting system that
must be considered, the latter is the more likely of the 2 to be encountere
d. Primary carcinoma of either the rete testis or the epididymis is a rare
occurrence; these entities are considered in some detail to allow for their
recognition and distinction from other tumors that may occur in this regio
n. Our own experience with 18 unpublished cases of lesions of the rate is a
