ABSTRACT
Endometriosis is relatively common gynecologic diseases, but pulmonary endometriosis is exceedingly rare among various types of external endometriosis. Patients with pleural pulmonary endometriosis present with chest pain, dyspnea, pneumothorax or pleural effusion in relation to menstruation. Patients with parenchymal pulmonary endometriosis present with hemoptysis at the time of menstruation, with or without lung lesions on their chest X-ray. The diagnosis of pulmonary endometriosis is usually made on the basis of the clinical history and the exclusion of other causes of recurrent hemoptysis including tuberculosis, bronchial carcinoid, pulmonary infarction, chronic bronchitis, congenital abnormalities and carcinoma. It can be treated by progesterone, GnRH agonist, Danazol, surgical treatment etc. Hereby we experienced 23 year-old multiparous woman with catamenial hemoptysis. The site of disease/was localized with bronchoscopy and chest CT scanning, and we treated her with Danazol. The literature associated with pulmonary endometriosis is briefly reviewed.
