Cutaneous mucinoses are a complex and diverse group of connective tissue disorders characterized by the accumulation of mucin and/or glycosaminoglycan in the skin and adnexa. Cutaneous focal mucinosis appears as a solitary, asymptomatic, skin-colored to white papule, nodule, or plaque located anywhere on the body or in the oral cavity. It presents mainly in adults and is characterized on histopathology by mucin throughout the upper and mid dermis. We describe the dermoscopy of two cases of cutaneous focal mucinosis. Both lesions presented a nonspecific homogenous whitish pattern; the first case also exhibited a sharply demarcated yellow border.
皮肤黏蛋白沉积症是一组复杂多样的结缔组织疾病，其特征是皮肤和附属器中黏蛋白和/或糖胺聚糖的蓄积。皮肤局限性黏蛋白沉积症表现为单个、无症状、肤色至白色的丘疹、结节或斑块，位于身体任何部位或口腔内。它主要发生于成年人，组织病理学特征为整个真皮上层和中层有黏蛋白。我们描述了两例皮肤局限性黏蛋白沉积症的皮肤镜检查情况。两个皮损均呈现非特异性均匀白色模式；第一例还表现出边界清晰的黄色边缘。
