Vitamin C Deficiency in an Adolescent With Severe Anorexia Nervosa.

This article reports on the case of a 14-year-old non-binary patient with anorexia nervosa - restrictive subtype (AN-R), presenting with severe malnutrition and the cutaneous manifestations of scurvy. Scurvy is an uncommon nutritional deficiency caused by a lack of dietary vitamin C. In this case, we highlight the clinical features of vitamin C deficiency, a rare but treatable nutritional deficiency that should not be overlooked in patients presenting with malnutrition, including those with eating disorders. This case reviews the pathophysiology, common clinical manifestations, and prevention of vitamin C deficiency and highlights pediatric populations at risk for the development of this condition.
