On histopathologic examination, many non-neoplastic conditions mimic benign or malignant neoplasms. Alternatively, some benign and malignant neoplasms can also mimic non-neoplastic lesions. This is true of all organ systemsskin is no exception. Examples of these mimickers can be found in skin lesions of almost all tissue types, including those that are melanocytic, lymphoid, epithelial, neural, vascular, neuroendocrine, and fibrohistiocytic. Melanocytic neoplasms are particularly important as it's challenging to differentiate them as being benign or malignant, and it's difficult to tell them apart from non-melanocytic neoplasms. This review illustrates examples of non-melanocytic lesions that disguise themselves as melanocytic.
在组织病理学检查中，许多非肿瘤性病变类似于良性或恶性肿瘤。相反，一些良性和恶性肿瘤也可以类似于非肿瘤性病变。所有器官系统都是如此——皮肤也不例外。这些类似物的例子可以在几乎所有组织类型的皮肤病变中找到，包括那些黑素细胞、淋巴样、上皮、神经、血管、神经内分泌和纤维组织细胞的病变。黑素细胞肿瘤尤其重要，因为区分它们是良性还是恶性具有挑战性，而且很难将它们与非黑素细胞肿瘤区分开来。本综述举例说明了伪装成黑素细胞的非黑素细胞病变。
