Cutaneous manifestations of dermatomyositis commonly include Gottron's papules, heliotrope rash, photosensitivity, poikiloderma and nailfold telangiectasia. Vesicles and bulla are rare. We report a patient with dermatomyositis who presented with blisters and oral ulcers. It is important to recognise this bullous variant in order to avoid a delay in diagnosis. Bullous dermatomyositis may also portend a poorer prognosis. Our patient was subsequently diagnosed to have undifferentiated nasopharyngeal carcinoma.
皮肌炎的皮肤表现通常包括Gottron丘疹、向阳疹、光敏性、皮肤异色症和甲褶毛细血管扩张。水疱和大疱较为罕见。我们报告了一名皮肌炎患者，其表现为水疱和口腔溃疡。认识到这种大疱性变体很重要，以避免诊断延误。大疱性皮肌炎也可能预示着预后较差。我们的患者随后被诊断为未分化鼻咽癌。
