[The Dubin-Johnson syndrome: case report and review of literature].

The Dubin-Johnson syndrome is a hereditary deficiency in the excretion ofconjugated bilirrubin by hepatocytes characterized by chronic hyperbilirubinemia, alteration in coproporphyrin metabolism, and intracellular deposition of a dark melanin-like pigment giving the liver a typical black cast. We report a 28-year-old male patient who presented conjunctival jaundice and conjugated-hyperbilirubinemia without no other alteration in hepatic biochemistry. The diagnosis of this syndrome was perfomed by using the low-risk methods of laparoscopy-facilitated hepatic biopsy and oral cholecystography In contrast, we avoided the classical Bromsulphalein test because of potential severe side effects.
