Autoimmune blistering disease in a patient with Graves disease and vitiligo.

Autoimmune thyroid diseases have been correlated with a variety of autoimmune diseases also affecting the skin. A 56-year-old patient with a history of vitiligo is presented who was admitted for hyperthyroidism (Graves disease) and a blistering eruption. Clinical and histological appearance of the skin disorder, rapid response to corticosteroids, recurrence and remission of the lesions with discontinuation and reintroduction of corticosteroids, respectively, were all suggestive of an autoimmune blistering disease accompanying autoimmune hyperthyroidism and vitiligo.
