Surgical Treatment for Inflammatory Pseudotumors of the Lung:With a report of 30 Cases

Aim:To discuss the etiology and surgical treatment of the inflammatory peseudotumors of the lung(IPL).Methods:30 cases of IPL surgically treated from 1989 to 1999 were reviewed.Results:Some cases had the evidence of inflammation while others had marked local invasion. All patients received surgery, including wedge or segmental resection in 11 cases,lobectomy in 15,pneumonectomy in 3 and exploration in 1.Preoperatively, 21(70%) cases were misdiagnosed as lung cancer or tuberculoma,only 9(30%) cases were suspected having IPL while lung cancer could not be excluded.There were no postoperative mortality and complications except one, who suffered from bronchopleural fistula but was cured soon after. half to five years follow up was given to 23 cases.Among them 2 cases died while the others were still alive without recurrence.Conclusion:Most probably,IPL is a ferm which includes diverse group of lesions that neither appear to be etiologically related nor can be subclassified under light microscope.Some of IPL may be real tumor.It is difficult to distinguish IPL from pulmonary adenocarcinoma and low grade sarcoma.Complete surgical resection should be performed as soon as diagnosis was made.Follow up should be given to the cases who have predominant infiltration of spindle cells under light microscope.
