The cutaneous manifestations of dermatomyositis range from classical in the case of heliotrope rash and Gottron papules to less common papulosquamous and edematous/vesiculobullous lesions; histopathologic descriptions are dominated by interface dermatitis. We present a case of dermatomyositis with a combination of common and rare skin findings, both clinically and histologically. Increased awareness of papulosquamous and edematous lesions of dermatomyositis can help direct patient care. Although uncommon, confluent parakeratosis and dermal edema can be manifestations of dermatomyositis.
皮肌炎的皮肤表现范围广泛，从典型的向阳疹和Gottron丘疹到较罕见的丘疹鳞屑性及水肿性/水疱大疱性损害；组织病理学描述以界面性皮炎为主。我们报告一例皮肌炎病例，其在临床和组织学上均兼具常见和罕见的皮肤表现。提高对皮肌炎丘疹鳞屑性和水肿性损害的认识有助于指导患者护理。虽然不常见，但融合性角化不全和真皮水肿可为皮肌炎的表现。
