Inflammatory pseudotumor

Overview Inflammatory pseudotumor is a benign lung tumor, is from the lungs of chronic granulomatous inflammation, aircraft, fiber and connective tissue diseases related to the formation of secondary mass, is not really cancer. Inflammatory pseudotumor more common. Cause pathogenesis of inflammatory pseudotumor of the pathological features of histology of polymorphous, Masses of granulation tissue containing the size range of cable Arrange the fibroblast cells, plasma cells, lymphocytes, cells, Intron epithelial cells and neutral fat and cholesterol foam cells or tumor cells Huang false, So many authors under the possession of the cell edge to set different names and types, such as pseudopapillary tumor type, fibrous histiocytoma type, the tumor type, fake lymphoma type. Pathogen and pathogenesis is not yet clear. Inflammatory pseudotumor of the lung parenchyma in general, involved only a small number of the bronchus. The vast majority of single hair, a round or oval-shaped nodules, no general integrity of the envelope, but mass than its predecessor, a well - Some have thicker cell and the lack of connective tissue collagen fibers and lung separately. Minorities inflammatory pseudotumor can be carcinogenic. Clinical manifestations of inflammatory pseudotumors majority of patients aged 50 years of age, more females than males. 1 / 3 of patients with no clinical symptoms, only occasionally in the X-ray examination found that 2 / 3 of patients with chronic bronchitis, pneumonia, suppurative lung disease history, and the corresponding clinical symptoms, such as cough, expectoration, low heat, some patients have chest pain, hemoptysis, even hemoptysis, but hemoptysis was typically less. Diagnosis of Inflammatory Pseudotumor in the diagnosis of certain difficulties, Clinical symptoms of patients with difficult and chronic bronchitis and lung cancer identification. Chest X-ray examination of round or oval, smooth, sharp edge nodules, some fuzzy edge, it is a burr or lobulated, and lung cancer is very difficult to identify. Inflammatory pseudotumor of the lung without clear the lesion size from 1 cm to 16cm, mostly in the following 4cm. All this has caused difficulties in diagnosis. Due to the treatment of inflammatory pseudotumor precise preoperative diagnosis is difficult and especially difficult to distinguish between lung cancer, the cancer may occasionally, So early advocate general surgery. For exploration that can be seen under the initial judgment and, if necessary, send pathological frozen biopsy for diagnosis. Determine the nature of a benign, surgery to try to preserve normal lung tissue as a principle. At the surface of the lung inflammatory pseudotumor, it is not difficult to remove. In the lung parenchyma inflammatory pseudotumor punishment Ke trip to wedge resection or partial lung resection, Apart from great mass and has been invaded and bronchus, and usually not in the entire lung lobe resection. Surgery prognosis is good.
