Abstract
Endometriosis is still an etiologic mystery. Benign metastasis from the uterine cavity by way of the lymphatics or tubal reflux is probably the mechanism of development. Treatment in the younger patient focuses on relieving pain and improving fertility. Surgical exploration and piecemeal excision provide the best results. Certain hormonal preparations appear to control the disease or hold it in abeyance. In the older patient total excision often provides cure without associated premature menopause.
