Scurvy: An Unexpected Nutritional Complication in an Adolescent Female With Anorexia Nervosa.

Vitamin C deficiency results in the clinical presentation of scurvy, a disease that is rare among the adolescent population. Individuals with unusual dietary habits, mental illness, or physical disability are more prone to develop scurvy. We present a case report of a previously healthy 16-year-old female presented to the hospital with a 12-month history of anorexia nervosa, restrictive subtype. She was admitted to the intensive care unit and transferred to a tertiary care pediatric eating disorder program for the treatment of extreme weight loss, cardiovascular instability, and refeeding syndrome. On examination, she had multiple tiny hyperpigmented perifollicular petechial papules on the lower abdomen, dorsum thighs, and extensor surfaces of the arms with corkscrew hairs on the abdomen. Dermatologic examination and laboratory investigations were consistent with a diagnosis of scurvy. The patient's vitamin C serum level was 21 μmol/L (.23 mg/dL; reference range 25-114 μmol/L [.28-1.28 mg/dL]). She was treated with ascorbic acid orally. Objective cutaneous findings improved within 4 weeks of supplementation, and after 6 weeks, repeat levels of vitamin C levels were 102 μmol/L (1.15 mg/dL). To the best of our knowledge, this is the first case of an adolescent female with anorexia nervosa and cutaneous manifestations of scurvy that resolved after the oral administration of vitamin C.
