Inflammatory pseudotumor of the liver with occlusive endophlebitis: report of a case.
Inflammatory pseudotumor (IPT) of the liver is an extremely rare benign tumor. Only 12 cases have so far been reported in the English literature. The etiology and pathogenesis of IPT remain obscure. We herein present an additional case of IPT of the liver with occlusive endophlebitis in a 36-year-old female. Immunohistochemical studies demonstrated the polyclonal nature of the plasma cells in the tumor, including IgA, IgM, IgG, kappa and lambda. The inflammatory pseudotumor should be kept in mind in the differential diagnosis of hepatic space-occupying malignant lesions.
