Difficult to think about but easy to treat: scurvy.

Objectives: Severe vitamin C deficiency, or scurvy, presents as a syndrome of multisystem abnormalities associated with defective collagen synthesis and antioxidative functions. The many clinical features of scurvy lead to frequent misdiagnoses, as they can often point to other diseases, such as vasculitis, venous thrombosis and musculoskeletal disorders. As such, an extensive workup is recommended in cases in which scurvy is suspected.
