Surgically treated pulmonary inflammatory pseudotumor.

We report 2 cases diagnosed as so-called pulmonary inflammatory pseudotumor. In case 1, a 28-year-old man with a slow growing 6-cm pulmonary tumor who underwent a right upper lobectomy was diagnosed with an inflammatory myofibroblastic tumor. In case 2, a 55-year-old man with chest pain and cough, who underwent open lung biopsy was diagnosed with plasma cell granuloma. Despite both diagnoses being classified as pulmonary inflammatory pseudotumors, we believe they should be classified differently.
