Kwashiorkor - Skin
Although predominantly a disorder of developing countries, cases of kwashiorkor in the United States have been described in children in extreme poverty or with presumed food allergies on faddish or avoidance diets. Kwashiorkor usually presents in infancy or early childhood, typically soon after the child has been weaned off breast milk. The clinical findings of kwashiorkor must be distinguished from those of other nutritional deficiencies, and any underlying disease—malabsorption, immune deficiencies and infections—must be ruled out.
