A Woman with Recurrent Hemoptysis, a Rare Etiology

Bronchopulmonary endometriosis is a rare clinical entity of thoracic endometriosis syndrome (TES). The diagnosis is often delayed because of high index of clinical suspicion is needed. We submit a case of 32-year-old healthy woman presenting with recurrent non-massive hemoptysis with the onset of menses for six months. Computed tomography scans of the chest revealed ill-defined ground glass opacity in superior segment of right lower lobe. Fiberoptic bronchoscopy was performed during the menstruation showed diffuse erythema along distal trachea through lobar bronchus. These findings disappeared when repeated at the end of menstrual cycle. Cytologic findings of bronchial wash suggested the evidence of old hemorrhage and the endometrial cells. After treatment with depot medroxyprogesterone acetate, hemoptysis did not occur for 12 months of follow-up. Based on clinical features and response to treatment, bronchopulmonay endometriosis was diagnosed.
