摘要
“色素病变”通常指黑素细胞痣。皮肤科中有些疾病虽然表现为色素沉着，但其本身并不是黑素细胞病变（如血管病变、脂溢性角化病和色素性基底细胞癌），这些病变均具有明确的诊断特征，因此，本文仅讨论黑素细胞痣。
The term‘pigmented lesion＇usually refers to melanocytic naevi （‘ moles＇）. There are non-melanocytic lesions that appear pigmented（e. g. vascular lesions, seborrhoeic keratoses, pigmented basal cell carcinomas）, all of which have distinctive diagnostic features. This contribution discusses melanocytic naevi only.
