Reversible AIDS-related sclerosing cholangitis.

Although hepatobiliary involvement is common in the acquired immunodeficiency syndrome, it infrequently leads to biliary tract abnormalities. We describe a 39-year-old man with human immunodeficiency virus infection and no previous acquired immunodeficiency syndrome-defining illnesses, who presented with malaise, right upper quadrant pain, lymphadenopathy and cholestasis. An endoscopic retrograde cholangiopancreatography demonstrated sclerosing cholangitis due to disseminated B-cell nonHodgkin's lymphoma. Following chemotherapy, his symptoms and signs rapidly improved, so that 1 month later his endoscopic retrograde cholangiopancreatography had returned entirely to normal.
