Abstract

Dubin-Johnson syndrome (DJS), a congenital metabolic disorder of bilirubin excretion, was classically diagnosed by the bromsulfalein (BSP) curve and needle hepatic biopsy methods. We present three cases of DJS and propose a new diagnostic approach which could conceivably become a substitute for more aggressive techniques. The results of the 24-h urine coproporphyrin determination and 99mTc-Disofenin scintigraphy gave, together, enough data for an accurate diagnosis.
