A rare coexistence of Behcet’s disease and Graves’ thyrotoxicosis in a young man: a case report

Behcet’s disease is a recurrent systemic vasculitic disorder. It manifests most commonly in the form of skin lesions, oral and genital ulcers and uveitis. Graves’ thyrotoxicosis is an autoimmune disorder characterized by excessive production of thyroid hormones. We present a case of a 41-year-old male of Turkish descent who had symptoms of arthralgia, rash, palpitations and weight loss. Bloods tests showed raised inflammatory markers and biochemical evidence of severe autoimmune thyrotoxicosis. The patient was HLA-B51-negative, and pathergy test was inconclusive. A diagnosis of Behcet’s disease was made on constellation of clinical symptoms. The patient was treated with carbimazole and prednisolone followed by azathioprine. The coexistence of Behcet’s disease and Graves’ disease in the same patient is very rare. Further studies are required to determine if there is a pathological association between these two conditions.
