Pulmonary hypertension secondary to vitamin C deficiency: A case report.

Scurvy is a rare disease caused by exogenous ascorbic acid deficiency. It should be considered in atrisk groups, such as patients with neurodevelopmental disorders who present restrictive diets due to food selectivity. Although pulmonary hypertension associated with vitamin C deficiency is extremely rare, its occurrence is possible. Signs and symptoms such as edema, tachycardia, palpitations, and dyspnea should raise suspicion about the diagnosis. In most cases, this condition is transient and can be reversed with early diagnosis and adequate supplementation with ascorbic acid. We present a case of a patient with autism spectrum disorder and vitamin C deficiency who developed pulmonary hypertension.
