Figure 1. A 23-year-old woman who was admitted for jaundice was found to have yellow-orange discoloration of her skin (her hand is shown on the right, and the hand of a subject without hypercarotenemia is shown on the left). Her sclerae were not discolored. The serum bilirubin level was normal. High-performance liquid chromatography showed a marked increase in serum beta carotene levels. The patient was a vegetarian and had been eating a low-calorie diet with a high content of orange juice, pumpkin, and carrots. Other causes of hypercarotenemia, such as hyperlipidemia, diabetes mellitus, hypothyroidism, and porphyria, were excluded.
