Localized plasma cell variant of Castleman's disease is an uncommon lymphoproliferative disorder. It is characterized by numerous, evenly distributed germinal centres with moderate or extensive sheets of plasma cells in between. It may be associated with a wide variety of systemic manifestations that disappear after removal of lesion. Rare cases of Castleman's disease have been reported in extranodal locations, i.e. muscle, larynx, vulva, lung, pericardium and cranium. We report the first the case of a liver tumour with clinico-pathological features of the plasma cell variant of Castleman's disease. This tumour differs from the hepatic inflammatory pseudotumour, which is frequently associated with infectious conditions.
