RESUMO
INTRODUCTION: Dermatomyositis is an important inflammation of skin and muscles. Generalised itch is frequent in the condition; however, symptomatic dermographism has not previously been reported as a presenting feature. CASE PRESENTATION: A 32-year-old Caucasian Scottish woman was diagnosed with dermatomyositis after initial presentation with symptomatic dermographism. No underlying neoplasm was found and her condition was successfully treated with systemic corticosteroids and high-dose human immunoglobulin infusions. At presentation, her troponin T and creatine phosphokinase enzymes were highly raised. CONCLUSION: Symptomatic dermographism may be a presenting feature of dermatomyositis. Dermatomyositis is one of many conditions that can result in a raised troponin T.
