abstract={Pulmonary arterial hypertension (PAH) describes a rare, progressive disease of the pulmonary vasculature, involving a group of clinical conditions that result in precapillary pulmonary hypertension (PH). PAH is characterized by proliferative vasculopathy, and subsequent right heart failure. For the past several decades research has focused on identification of underlying molecular causes of this disease. Recently, there have been a number of reported cases of patients with scurvy developing pulmonary arterial hypertension. Thus, it has been hypothesized that vitamin C deficiency results in non-hypoxic activation of hypoxia inducible transcription factors (HIF) and low nitric oxide (NO) level in the pulmonary vasculature, leading to subsequent pulmonary vasculopathy and an exaggerated pulmonary vasoconstrictive response. Immediate supplementation of vitamin C is considered the definitive treatment, preventing an otherwise fatal outcome. In this paper, we describe a patient with a fatal case of scurvy related PAH, who was admitted with ecchymosis, oral ulceration, and dyspnea.},
