[Inflammatory pseudo-tumors of the liver. Apropos of 2 cases]

Inflammatory pseudotumors of the liver (IPTL) are a reaction pathology of most often mysterious etiology. This is an ill-known clinicopathological entity, of which 13 cases only have been reported. The authors report about 2 cases for which an infectious or parasitic etiology can be suggested. They sum up the characteristics of these pseudotumors, which are most often single, solid, preferentially developing in the right liver. The clinical signs of these lesions are pain and fever, associated to jaundice in case of pedicular extension. From a morphological and macroscopic point of view, IPTLs have the features of a primary or secondary malignant tumor. Cytological puncture usually fails. The diagnosis can be based only on an extensive surgical biopsy or the study of the specimen of liver exeresis. Finally, IPTLs are characterized by a spontaneously regressive evolution. This notion justifies a prudent, even conservative surgical attitude.
