Treatment of pulmonary endometriosis with danazol

A successful treatment of pulmonary endometriosis with Danazol is reported. A 25-year-old woman who suffered from hemoptysis during her menstrual periods was at first treated with lynestrenol, but the hemoptysis recurred immediately after treatment. Following 6 months' therapy with Danazol she has now been symptom-free for 12 months. Danazol appears to have a more lasting effect on ectopic foci of endometriosis than has progestin.
