[Exertional dyspnea, myalgia, petechiae of the lower extremities and pronounced gingivitis in a 64-year-old female patient]. / Belastungsdyspnoe, Myalgien und Petechien der unteren Extremitäten sowie ausgeprägte Gingivitis bei einer 64-jährigen Patientin.

A female patient presented with exertional dyspnea, myalgia, a petechial rash of the lower extremities and pronounced gingivitis. The biochemical test results showed the presence of anemia. The patient had a known eating disorder and on questioning about eating habits admitted that she did not eat any fruit or vegetables. This led to the suspicion of a vitamin C deficiency, which was confirmed by high-pressure liquid chromatography. The patient was subsequently treated with 1000 mg ascorbic acid daily for 1 month whereby the clinical symptoms and anemia improved within a few weeks.
