Haemoptysis as a primary manifestation of cryptogenic organizing pneumonia (COP).

Abstract

Cryptogenic organizing pneumonia (COP), previously called bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathological disorder of unknown aetiology but increasingly reported. It usually presents with symptoms of dyspnea, cough, fever, weight loss accompanied by the presence of alveolar opacities on chest radiograph. Haemoptysis, described as blood streaking has only rarely been reported as primary presentation of COP. Herein, we report a case of COP in which submassive haemoptysis was the main clinical manifestation. The clinical, radiological, pathological, and therapeutic aspects of the disease are briefly discussed. Cryptogenic organizing pneumonia should be taken into consideration in the differential diagnosis of severe haemoptysis.
