The diagnosis of pigmented nail lesions is a concern for both general practitioners and dermatologists, due to the possibility of indicating nail melanoma. The origin of the dark pigmentation can be either melanocytic or non-melanocytic (fungi, bacteria, or blood), and clinical evaluation alone may not be sufficient for differentiation, requiring additional exams. Onychoscopy provides valuable information prior to biopsy. The causes of nail pigmentation will be described to aid in the differential diagnosis.
甲色素病变的诊断是全科医生和皮肤科医生共同关注的问题，因为这可能提示黑素瘤。色素的来源可以是黑色素细胞或非黑色素细胞（真菌、细菌或血液），仅凭临床评估可能不足以进行鉴别，需要进行其他检查。在活检前，甲下镜检查可提供有价值的信息。本文将对导致甲色素沉着的原因进行描述，以帮助进行鉴别诊断。
