Feline Cystic Rete Ovarii

Abstract

Cysts of the rete ovarii system from 20 cats are described. The cellular morphology of these cysts varies because the normal rete ovarii in the cat consists of three anatomically distinct parts. Cysts arise in the ovarian medulla or at the tubal extremity of the ovary, expand into ovarian stroma rather than the mesovarium , and are lined by ciliated columnar to flattened epithelium. Their functional significance is unknown.
