A Case of Pneumocystis Carinii Pneumonia with Diffuse Pulmonary Hemorrhage

Pneumocystis carinii pneumonia (PCP) is an infectious disease of immune-compromised host.Sometimes it is difficult to differentiate PCP with diffuse pulmonary hemorrhage.Association between PCP and diffuse pulmonary hemorrhage has been reported in 30% of PCP with HIV positive patients.But association between PCP and diffuse pulmonary hemorrhage has not been reported in non-HIV positive patients without any known underlying causes of diffuse pulmonary hemorrhage.We report a case of PCP with diffuse pulmonary hemorrhage in 66 years old male patient.We confirmed PCP and diffuse pulmonary hemorrhage with bronchoalveolar lavage.We can exclude the possible other causes of diffuse pulmonary hemorrhage except PCP.PCP may be one of possible cause of diffuse pulmonary hemorrhage in non-HIV immune compromised patient.(
