Pulmonary Inflammatory Pseudotumor

Pulmonary inflammatory pseudotumor is a relatively rare benign tumor located in the lungs but could occur in the mesentry, greater omentum, liver, bladder and upper respiratory tract. Most of the patients are under 40 years of age and complain mainly of non-specific symptoms. Lesions are shown as pulmonary nodules or masses in which the border can be characteristically well distinguished on X-ray. Diagnosis of this tumor is difficult without surgical biopsy or resection. It is principally treated with surgery. This tumor was reported as fibrous histiocytoma, plasma cell granuloma and inflammatory pseudotumor in Korea. A total of 27 cases of pulmonary inflammatory pseudotumor have been reported in Korea, Pulmonary Inflammatory Pseudotumor -A report of 28 cases-
