Vitamin C deficiency presenting with mucosal bleeding and worsening dyspnea in severe pulmonary arterial hypertension: a case report

Background

Scurvy is rare in developed countries but continues to occur in individuals with limited dietary variety. Vitamin C deficiency is an underrecognized and potentially reversible cause of mucocutaneous bleeding, anemia, and systemic symptoms. We report a case of vitamin C deficiency presenting with mucosal bleeding and progressive dyspnea in a patient with severe pulmonary arterial hypertension (PAH).
