Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor (IP) has  been discussed in details worldwide as primary tumor of the lung and upper respiratory tract. Histologically, IMT is characterized by a proliferation of spindle cells admixed with variable aounts of lymphoplasmacytic infiltrate. However, reporting of cases involving liver and biliary tree has increased over recent years some of them as a Klatskin’s tumor. The terms IMT sug-gested by World Health Organization in recent classification of soft tissue tumors probably cover many various tumors which have common only one feature-inflammatory infiltrate of neoplastic tissue. There are more immunohistochemical evidences, that some of them are in fact follicular dendritic reticulum cell tumor (FDRcT) usually connected with Epstein-Barr infection. There are also cases of IMT with expression of Anaplastic Lymphoma Kinase (ALK-1)  expression. Recently, association with sclerosing cholangitis, especially IgG4-related variant and/or autoimmune pancreatitis was also described. The present review describe pathological aspect of this heterogenous group of tumors.
