Malnutrition is commonly observed in children in developing countries and is a major cause of multiple illnesses. Kwashiorkor in children is characterized by generalized edema and develops as a result of protein-calorie deficiency, whereas marasmus results from calorie and energy deficiency. We report a case of an 11-month-old female infant who presented with fever, cough, and excessive crying for 2 days. She was normal 2 days back, then developed high-grade fever, which is acute in onset, intermittent, relieved by medications, with multiple spikes with kwashiorkor features as idiopathic. The child also presented with hepatomegaly, hypoalbuminemia, hypoproteinemia, and elevated transaminases. Children with kwashiorkor typically have a very low plasma albumin concentration due to protein deficiency.
