Hyperbiliverdinemia can manifest as green jaundice, which is a green discoloration of the skin, urine, serum, and other bodily fluids, due to increased biliverdin resulting from inefficient conversion to bilirubin. Although rarely reported, affected individuals appear to have symptoms only in the context of obstructive cholestasis and/or liver failure. In some cases, green jaundice can resolve after resolution of obstructive cholestasis. Green jaundice has also been associated with malnutrition, medication, and congenital biliary atresia (summary by Huffman et al., 2009).
