The results of laboratory examinations revealed a normal white blood cell count, a hemoglobin level of 76 g/L, and a platelet count of 334 × 109/L. The serum calcium, phosphorous, copper, and alkaline phosphatase levels were normal. Thyroid stimulating hormone, triiodothyronine, and thyroxine levels were also normal. The serum level of vitamin D was normal, but vitamin C levels were low, 28 µmol/L (reference range, 45-108 µmol/L). Chest x-ray film showed a scorbutic rosary at the costochondral junctions with a "corner" sign noted in the proximal metaphysis of the humerus. Lower extremity radiographs demonstrated abnormalities (Figure 3).
