Carotenemia and hepatomegaly in an atopic child on an exclusion diet for a food allergy.

Eczema is a frequent childhood manifestation and a few atopic children are allergic to certain foods or aeroallergens. Anxious parents of atopic children often have a fear of topical steroid-related side-effects, and some may try a range of elimination diets to avoid allergies. Elimination diets increase the risk of anaphylaxis on re-exposure to previously tolerated foods from the loss of oral tolerance. Unbalanced diets together with an inadvertent excessive consumption of fruits and vegetables may lead to carotenemia from the carotenoids in the plant foods. Carotenemia is benign but unusual diets and the consumption of preformed vitamin A in health supplements can lead to vitamin A toxicity. We discuss a child with eczema on an exclusion diet presenting with anaphylaxis to dairy food. He had carotenemia with hepatomegaly, which resolved on dietary management.
