title: Primary intestinal T-cell lymphoma and sclerosing cholangitis: a cytokine-mediated association?
abstract: A 63-year-old woman with a 1-year history of abdominal pain and intrahepatic cholestasis developed anorexia, weight loss, lassitude and diarrhoea. Studies led to a diagnosis of primary intestinal T-cell lymphoma involving especially the proximal small intestine and infiltrating the mesenteric lymph nodes, bone marrow and skin. An associated severe hypoalbuminaemia (1.3 g dL-1) was most probably the result of protein-losing enteropathy. Liver biopsy demonstrated concentric fibrosis of the bile ducts ('onion skin' lesions, with an inflammatory cell infiltrate and lymphoid aggregates) and was considered almost pathognomonic of primary sclerosing cholangitis. Sudden death due to pulmonary embolism occurred and a limited autopsy confirmed the diagnosis. Other associated diseases such as coeliac disease or inflammatory bowel disease were not found. This first report of the simultaneous occurrence of two rare diseases - primary sclerosing cholangitis and intestinal T-cell lymphoma - may indicate an intriguing association, possibly mediated by the effect of cytokines released by the infiltrating T-cells into the portal circulation.
