黑素细胞痣伴重度黑素细胞非典型增生

定义

黑素细胞痣伴严重黑素细胞发育不良是一种组织病理学诊断，其基础是存在严重的细胞异型性，定义为增大的梭形和上皮样黑素细胞，细胞核深染（通常至少是基底角质形成细胞两倍大小）和明显的核仁。这种痣往往是不规则大小和色素沉着，由于担心它们可能代表早期黑色素瘤而被切除。

Melanocytic naevus with severe melanocytic dysplasia is a histopathological diagnosis based on the presence of severe cytological atypia, defined as enlarged, spindle- and epithelioid-shaped melanocytes with hyperchromatic nuclei (typically at least twice the size of those of basal keratinocytes) and distinct nucleoli. Such naevi tend to be irregular in size and pigmentation and to have been excised because of concern that they may represent early melanoma.
