Rete Testis Dysgenesis
- 3 Downloads
The term rete testis dysgenesis refers to the presence of a rete testis with infantile characteristics in the adult, absence of development of the rete testis cavities, and persistence of a cubic epithelium instead of the squamous epithelium of the adult. It is associated in many cases with a ductal, pseudoglandular, or papillary proliferation of this epithelium.
Frequent in the undescended testes removed in the adult (Nistal et al. 1997).
It is a lesion preferably of adults although congenital forms are also observed.
Both testes. No predilection of laterality.
It is a benign process that probably has its beginning in fetal life due to its association with undescended testes or germ cell tumors, so it should be included among the histological lesions of the testes with testicular dysgenesis...
