Dermatomyositis is an autoimmune inflammatory myopathy characterized by unique cutaneous features. Gottron's papules are pathognomonic, lichenoid papules that can be found overlying the joints of the dorsal hand. Papules on the palms of the hand are less commonly seen, especially in the pediatric age group. Recognition of these inverse Gottron's papules as a sign of dermatomyositis is important as they may be the only cutaneous feature and may be a clue of underlying interstitial lung disease.
皮肌炎是一种自身免疫性炎性肌病，其特征为具有独特的皮肤表现。Gottron丘疹具有诊断意义，是一种苔藓样丘疹，可出现在手背关节上方。手掌上的丘疹较少见，尤其是在儿童年龄组。认识到这些反向Gottron丘疹是皮肌炎的体征很重要，因为它们可能是唯一的皮肤表现，并且可能是潜在间质性肺病的线索。
