1 a yellowish discoloration sometimes seen in degenerating tissues of malignant diseases.

3 a reversible yellow discoloration of the skin most commonly caused by the ingestion of large amounts of yellow or orange leafy vegetables containing carotene pigment. The antimalarial drug quinacrine, if taken over a prolonged period, may produce a similar skin color. Xanthosis may be differentiated clinically from jaundice because the sclerae are colored yellow in jaundice but are not discolored in xanthosis. Also called carotenosis. See also carotenemia.
