Massive ascites--an uncommon presentation of endometriosis.

Endometriosis as a cause of massive ascites is very rare. It is seldom possible to arrive at the diagnosis without surgical exploration. We describe a case of this entity which presented to us as a surgical problem. This proved to be a diagnostic dilemma to us and our colleagues in other disciplines, with the diagnosis being made based on histology after surgical exploration. The literature is reviewed and we hope our experience in this case will increase the awareness of this uncommon entity.
