Histopathological diagnosis of endobronchial endometriosis treated with argon laser

Abstract

The authors present a case of endobronchial endometriosis with catamenial haemoptysis. The lesion was diagnosed as endobronchial endometriosis based on histopathological examination of a bronchial biopsy from the right second carina. Fibreoptic bronchoscopic examination revealed a tiny hyperaemic submucosal area with bleeding and a brown-coloured diverticulum at bottom of this lesion encompassing a 2-cm2 area at the right second carina. Multiplanar reconstructions of a spiral CT scan revealed a 0.5-cm lesion that looked like a diverticulum at the right second carina. The patient was treated with argon laser at bronchoscopy. Following treatment, the patient has been asymptomatic with no recurrence of haemoptysis.
