Diagnostic Considerations

Differential diagnosis in carotenemia includes the following:

  • Excess ingestion or percutaneous absorption of chemicals - Eg, quinacrine, mepacrine, dinitrophenol, saffron, tetryl, picric acid, canthaxanthin
  • Sorafenib - Yellow skin discoloration can be associated with use of the oral, multitargeted tyrosine kinase inhibitor sorafenib for treatment of metastatic renal cell carcinoma [19]
  • Lycopenemia - Appears as an orange-yellow skin discoloration resulting from the ingestion of large amounts of tomatoes or other fruits containing lycopene
  • Type III hyperlipoproteinemia - A rare form of dyslipidemia, this condition was described with lycopenemia; it includes orange discoloration of xanthomas following serum lycopene elevation unassociated with excessive dietary intake [20]
  • Riboflavinemia
  • Diabetes mellitus
  • Hypothyroidism
  • Anorexia nervosa
  • Liver disease
  • Kidney disease
  • Inborn errors of metabolism
  • Familial conditions - May be associated with carotenemia
