Large intraligamentous cysts. Technique of surgical removal and correlation of surgical observations and histologic findings pertaining to origin.

Two recent pathologically oriented reports suggest that surgically significant parovarian cysts are most often of mesothelial origin rather than mesonephric or paramesonephric origin, as traditionally thought. In a series of eight large intraligamentous parovarian cysts, seven were considered to be of paramesonephric origin on the basis of both surgical and histologic observations. Determining the origin of these cysts has relevance from a surgical point of view in the younger patient.
