POEMS syndrome with idiopathic portal hypertension: autopsy case and review of the literature.
Polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes (POEMS) syndrome is a rare multi-system disease. Reported herein is an autopsy case of POEMS syndrome in a subject who developed idiopathic portal hypertension (IPH). The patient was a 38-year-old woman who was initially admitted to the Saiseikai Central Hospital because of polyneuropathy and edema. Diagnosis of POEMS syndrome was established on additional symptoms (splenomegaly and papilloedema) and serum M-protein. Corticosteroid was given for 10 years. The patient was admitted again at the age of 48 years because of gastrointestinal bleeding due to portal hypertension. The patient died of hepatoencephalopathy at 58 years of age. The liver at autopsy demonstrated dense portal fibrosis and obliteration of small portal vein branches, which are characteristic histological findings of IPH. Portal hypertension is a rare symptom in POEMS syndrome. Only three cases of IPH associated with POEMS syndrome (including the present one) have been reported so far. In the previous two reports, liver biopsy failed to determine the cause of portal hypertension. This is the first report on the occurrence of histological findings compatible with IPH in the liver. Although it is not confirmed whether IPH is related to POEMS syndrome, elevated serum cytokines such as vascular endothelial growth factor and coagulation abnormality could have contributed to the development of IPH in the present case.
