A 72-year-old man presented to our ED less than 24 hours following the acute onset of nausea, vomiting, and diarrhea. Within 12 hours of symptom onset, he noted bilateral lower extremity pain and swelling. His pain was associated with a new violaceous irregular rash on the anterior aspect of both feet and legs. There was no history of inciting trauma or recent wounds. In addition, there was no history of consumption of raw or undercooked food (including seafood) or recent change in food source. There was accompanying fever and chills for the same duration and painful swelling of his left thumb. His comorbidities included stage IIIb classical Hodgkin lymphoma diagnosed 4 months prior. His last dose of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy was 4 days before presentation. He had previously failed anti-CD30 monoclonal therapy resulting from attributed pancolitis.

She had a history of bipolar disorder and attention-deficit/hyperactivity disorder but had stopped her psychiatric medications for the past 4 days secondary to loss of insurance coverage. History was limited due to the patient's altered state and confusion, and was obtained from family. There was no history of headache, loss of consciousness, weakness of extremities, seizures, fever, or recent trauma. The patient's medical history also included cocaine abuse.

We report a case of a man in his 60s who developed pulmonary arterial hypertension (PAH) in association with profound vitamin C deficiency. Decreased availability of endothelial nitric oxide and activation of the hypoxia-inducible family of transcription factors, both consequences of vitamin C deficiency, are believed to be mechanisms contributing to the pathogenesis of the pulmonary hypertension. The PAH resolved following vitamin C supplementation. The current case highlights the importance of testing for vitamin C deficiency in patients with PAH in the proper clinical setting.
