What is marasmus?

Marasmus (from the Greek meaning wasting), or childhood caloric malnutrition, is a combined or proportional energy and protein deficiency with resultant catabolism and utilization of muscle and fat. There are no specific or significant skin findings. Infants often demonstrate a “monkey facies” due to loss of buccal fat that normally gives the face a rounded appearance.
