エキシマライト照射とビタミンD₃外用の併用が有効であったSjögren症候群を合併した尋常性白斑の1例

抄録

A 72-year-old Japanese woman presented in July 2012 with a 5-year history of depigmented areas on the face. On physical examination, she had multiple well-demarcated depigmented areas on the face and neck. She had also experienced increased thirst for the past 3 years. A blood sample was positive for antinuclear and anti-SS-A antibodies. A biopsied specimen from the lower lip showed dense focal lymphoid infiltration in the minor salivary glands. The patient was diagnosed with vitiligo vulgaris associated with Sjögren syndrome. Internal treatment with L-cysteine, tocopherol nicotinate and topical tacrolimus was of limited efficacy. Subsequent excimer light irradiation together with topical vitamin D₃ administration led to repigmentation around the hair follicles without causing photodermatosis. These treatments appear to be effective for patients with vitiligo vulgaris associated with Sjögren syndrome who have no past history of photosensitivity.
