Cutaneous manifestations of dermatomyositis (DM) commonly include Gottron's papules, cuticular erythema and telangiectasia, periorbital edema with a "heliotrope" rash, a papulosquamous eruption of the hairline, face, and trunk, as well as poikiloderma. Very few references can be found concerning vesicular and bullous lesions, however. We present two patients with dermatomyositis who manifested vesicular and bullous lesions who were initially misdiagnosed. Although rare, it is important to recognize this form of DM to avoid misdiagnosis. Furthermore, in some cases, vesiculo-bullous DM may portend a poor prognosis.
皮肌炎（DM）的皮肤表现通常包括Gottron丘疹、表皮红斑和毛细血管扩张、伴有“向阳性”皮疹的眶周水肿、发际线、面部和躯干的丘疹鳞屑性皮疹以及皮肤异色症。然而，关于水疱和大疱性皮损的参考文献却很少。我们报告了两名表现为水疱和大疱性皮损的皮肌炎患者，他们最初被误诊。尽管罕见，但认识到这种形式的皮肌炎以避免误诊很重要。此外，在某些情况下，水疱大疱性皮肌炎可能预示预后不良。
