Primary sclerosing cholangitis associated with massive intraabdominal lymphadenopathy.

A 40-year-old man with a history of insulin-dependent diabetes mellitus was admitted to the hospital because of jaundice and pruritus. During his evaluation the diagnosis of primary sclerosing cholangitis and "microscopic" ulcerative colitis were established. Massive intraabdominal lymphadenopathy was discovered on CT scan and histological examination eventually proved this to be follicular hyperplasia. The case herein reported documents the association of primary sclerosing cholangitis with diabetes mellitus and ulcerative colitis as well as reporting the occurrence of massive intraabdominal lymphadenopathy.
