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.
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.
Symptomatic dermographism may be a presenting feature of dermatomyositis. Dermatomyositis is one of many conditions that can result in a raised troponin T.
皮肌炎是一种重要的皮肤和肌肉炎症。在这种疾病中，全身性瘙痒很常见；然而，症状性皮肤划痕症此前尚未被报道为一种首发特征。
一名32岁的苏格兰白人女性在首次出现症状性皮肤划痕症后被诊断为皮肌炎。未发现潜在肿瘤，她的病情通过全身用皮质类固醇和大剂量静脉注射人免疫球蛋白成功得到治疗。就诊时，她的肌钙蛋白T和肌酸磷酸激酶水平显著升高。
症状性皮肤划痕症可能是皮肌炎的一种首发特征。皮肌炎是可导致肌钙蛋白T升高的众多病症之一。
