DefinitionThis section has been translated automatically.
Rare generalized grayish-brown hyperpigmentation of the skin of unexplained cause in newborns after phototherapy (performed with blue light of wavelength 425-475 nm as therapy of hyperbilirubinemia). Occurs mostly with the less frequent increase in direct serum bilirubin, therefore phototherapy is contraindicated when direct serum bilirubin exceeds 2 mg/dl (Itoh S et al. 2017).
EtiopathogenesisThis section has been translated automatically.
There is probably a bilirubin-induced phototransformation of copper porphyrin. Apparently, the liver of the newborn lacks sufficient amounts of the enzyme biliverdin reductase to metabolize the accumulating pigments.
TherapyThis section has been translated automatically.
Avoid phototherapy for serum bilirubin > 2 mg/dl.
Progression/forecastThis section has been translated automatically.
Cheap. Mostly remission without specific therapy.
