The differentiation between benign and worrisome melanocytic lesions may be challenging in the absence of the glaringly obvious clinical features that define a cutaneous malignancy. In such situations, dermoscopy may prove useful in further defining characteristics that are more indicative of a benign lesion, which can ultimately help avoid an unnecessary biopsy. Recognizing of the dermoscopic findings of benign nevi, taking into consideration the predominant pigment pattern and its organization, may aid in the evaluation of pigmented lesions. Benign nevi tend to exhibit symmetry, regularity in shape, and uniformity of dermoscopic structures. This article reviews the clinical and dermoscopic features of common acquired nevi (dermal, compound, and junctional), blue nevi, and congenital nevi.
在缺乏明确的临床特征来定义皮肤恶性肿瘤的情况下，良性和令人担忧的黑色素细胞病变之间的区分可能具有挑战性。在这种情况下，皮肤镜检查可能有助于进一步确定更能表明良性病变的特征，最终有助于避免不必要的活检。认识良性痣的皮肤镜检查结果，考虑到主要的色素模式及其组织，可以帮助评估色素病变。良性痣往往表现出对称性、形状规则和皮肤镜结构均匀性。本文综述了常见获得性痣（真皮痣、复合痣和交界痣）、蓝色痣和先天性痣的临床和皮肤镜特征。
