title: Dubin-Johnson syndrome--a clinicopathologic study of twenty cases.
abstract: Dubin-Johnson syndrome (DJS) is a rare benign chronic disorder of bilirubin metabolism, characterized by conjugated hyperbilirubinemia, darkly pigmented liver and presence of abnormal pigment in hepatic parenchymal cells. This is a retrospective study of twenty cases of DJS highlighting their major clinical and pathological findings. Liver biopsies were available in all the cases, obtained during a fourteen-year period (January 1991 to March 2005). The patients' age ranged from 7-63 years (median 21 years). These twenty cases comprised 13 males and 7 females. Major clinical manifestations were recurrent or persistent jaundice, abdominal pain and fever. Duration of illness ranged from 9 months to 58 years (median 10 years). All of them had conjugated hyberbilirubinemia and total serum bilirubin levels ranged between 1.4-13 mg/dl (mean 4.4 mg/dl). Liver biopsies revealed presence of coarse granular brown pigment in the cytoplasm of hepatocytes more concentrated in the pericanalicular region and more prominent in centrilobular hepatocytes. Associated findings were presence of hepatitis B virus related chronic hepatitis (1), history of tubercular lymphadenitis (1), chronic cholecystitis in (2), coronary heart disease (1) and exacerbation during pregnancy (1).
