Abstract

A case of pulmonary plasma cell granuloma is reported. A 53-year-old man was pointed out an abnormal shadow in the lung field on a chest X-ray film taken for routine physical examination. It was diagnosed as plasma cell granuloma by a transbronchial lung biopsy at a local hospital. He had been observed at the outpatient clinic because he had no subjective symptoms. However he was admitted to our hospital due to sudden hemotysis. Heamophilus parainfluenzae was detected by sputum culture. Chest CT scan revealed a solitary round lesion 7×5cm in diameter in the right upper lobe. A right upper lobectomy with a wedge resection of the middle lobe was performed. Pathological examination revealed plasma cell granuloma with organizing pneumonia pattern. The cause of this lesion remains unknown, but it is usually considered to be some inflammatory or reactive lesions. In our case, pulmonary infection probably triggered the onset of clinical symptoms.
