What does xanthochroism mean?
Xanthochroism is the medical term for the yellowish discoloration of the skin and whites of the eyes that occurs when bile pigments, particularly bilirubin, accumulate in the body. It is the visible sign associated with jaundice and may accompany liver disease, obstruction of the bile ducts, excessive breakdown of red blood cells, or other causes. In veterinary and zoological contexts, xanthochroism also denotes predominantly yellow coloration, especially in birds' plumage. The word is more specialized than jaundice and is most often encountered in clinical descriptions, medical literature, and discussions of animal coloration. Its Greek components reveal its descriptive nature: xanthos means “yellow,” while chroos refers to skin. Together, they describe yellow coloration of the skin. For general readers, the word is chiefly useful as a more exact name for the visible manifestation of jaundice, while specialists may also use it to distinguish yellow pigmentation in animals.

"Xanthochroism can be a warning sign of liver, biliary, or blood-related disease."

How xanthochroism is actually used
This is a formal and relatively uncommon medical term; jaundice is much more common in ordinary clinical speech. It names the visible yellow pigmentation rather than identifying its underlying cause. The zoological sense is specialized and normally appears in discussions of coloration abnormalities in birds.
Easily confused with xanthochroism
Xanthoderma is yellow skin pigmentation often associated with carotenemia, whereas xanthochroism specifically denotes the bile-pigment yellowing characteristic of jaundice.
