The sentinel lymph node from a 72-year-old female with melanoma revealed a pigmented and spindled melanocytic proliferation in the capsule that extended into the trabeculae. Benign nodal nevi are uncommon but have been reported in lymph nodes of melanoma patients and less often in lymph nodes removed for other reasons. Nodal blue nevi are particularly rare. These melanocytic proliferations can be distinguished from metastatic melanoma by evaluation of the distribution in the node, morphologic characteristics and the assistance of immunohistochemistry.
一名72岁黑色素瘤女性患者的前哨淋巴结显示，包膜内有色素沉着且呈梭形的黑素细胞增生，并延伸至小梁。良性淋巴结痣并不常见，但在黑色素瘤患者的淋巴结中已有报道，在因其他原因切除的淋巴结中则较少见。淋巴结蓝色痣尤为罕见。通过评估这些黑素细胞增生在淋巴结中的分布、形态特征以及借助免疫组化，可以将其与转移性黑色素瘤区分开来。
