title: [A case of pulmonary plasma cell granuloma with a cavity].
abstract: Plasma cell granuloma of the lung is an uncommon and non-malignant neoplasm that may present difficulties in both diagnosis and management. We report a 52-year-old male who was admitted to our hospital due to fever and an abnormal shadow on chest roentgenography. Chest computed tomography revealed a tumor shadow with a cavity in the left upper lobe. However, neither bronchofiberscopy nor serum examinations suggested a diagnosis. Video-assisted thoracoscopic surgery (VATS) was performed and postoperative pathological examination of the resected specimen showed plasma cell granuloma. The postoperative course was uneventful. No recurrence was observed 10 months after the operation. As plasma cell granuloma of the lung is histologically benign, surgery should be performed to preserve the maximal residual lung with no lesion. VATS is the method of choice for treatment of pulmonary plasma cell granuloma.
