BILE PIGMENTS, see Bile. BILE INFARCT, the deposition of bile pigment in the kidney in jaundice of the newborn. A bile infarct forms in the papillae of the medullary substance of the kidney and is noticeable on cross-section in the form of orange-red stripes running radially corresponding to the course of the urinary tubules. Under the microscope, these stripes turn out to consist of bilirubin crystals located both inside the tubules and in the interstitial tissue (for details, see Bilirubin infarct).
