Catamenial hemoptysis.

Catamenial hemoptysis is a rare result of thoracic endometriosis. The long-term treatment of this condition remains controversial. An operation to remove the offending parenchymal endometrial tissue by pulmonary sparing, such as wedge resection, segmentectomy affords satisfactory treatment without the disadvantage of long-term hormone therapy and with the consequent suppression of normal menses and alteration of secondary sexual characteristics in a young woman.
