[A case report of carotenemia]

Area of Science:

• Dermatology
• Pediatrics
• Nutrition Science

Background:

• Carotenemia is a benign condition characterized by yellow skin discoloration, primarily caused by excessive dietary intake of carotene-rich foods.
• It is commonly observed in pediatric populations and is often mistaken for jaundice, necessitating accurate diagnosis.

Observation:

• A 14-year-old female presented with several months of yellow skin discoloration, particularly on palms and soles.
• Physical examination revealed no signs of anemia or icterus; liver and spleen were not enlarged.
• Laboratory tests showed normal liver function but significantly elevated serum carotene levels (460 µg/dL) compared to controls.

Findings:

• The patient's excessive daily intake of oranges for over a year was identified as the cause.
• Following dietary modification and nutritionist consultation, serum carotene levels decreased to 270 µg/dL within eight weeks.
• The patient's skin discoloration visibly improved after the dietary intervention.

Implications:

• This case highlights the importance of dietary history in diagnosing carotenemia.
• It underscores that carotenemia is a reversible condition with appropriate dietary management.
• Educating patients and families about balanced nutrition is crucial for preventing and managing carotenemia.
