A 33-year-old woman was referred to our hospital due to repeated spontaneous abortions and positive autoantibodies. She had noticed Raynaud's phenomenon 13 years earlier. We diagnosed scleroderma based on the presence of Raynaud's phenomenon, proximal scleroderma, presence of anti-centromere antibodies, and histological findings on skin biopsy. Neither lupus anticoagulant nor anti-cardiolipin-beta2-glycoprotein 1 antibody was detected. We administered tocopherol nicotinate. Five months after the initiation of the treatment, she became pregnant and later delivered a healthy baby.
