What conditions produce yellowish discoloration of the skin?
- Carotenoderma caused by excessive ingestion of carotene (e.g., yellow and orange vegetables such as carrots, sweet potatoes, and squash), lycopenodermia caused by excessive ingestion of lycopenes (e.g., red vegetables such as tomatoes and rose hips), and systemic administration of quinacrine can all cause yellowish skin discoloration unrelated to hyperbilirubinemia.
- The skin may also demonstrate a sallow, subtle yellowish hue in patients with profound hypothyroidism.
