A young Caucasian woman had a large area of blue-gray discoloration on the flank and palpable axillary lymph nodes. The discolored area had enlarged during a recent pregnancy, contained multiple subcutaneous nodules, demonstrated increased cellularity and mitotic activity, and was associated with an axillary lymph node containing black streaks within the capsule. Although the lesion was initially considered to be a metastatic malignant melanoma, re-evaluation showed it to be a benign cellular blue nevus with benign nevus-cell aggregates within a regional lymph node. We report this case to emphasize how cellular blue nevus can simulate malignant melanoma and to increase physician awareness of this benign variant of melanocytic nevus so that inappropriate surgery and chemotherapy can be avoided.
一名年轻的白种女性侧腹有一大片蓝灰色色素沉着区域，且腋窝淋巴结可触及。该色素沉着区域在近期妊娠期间增大，包含多个皮下结节，细胞增多且有丝分裂活性增加，同时伴有一个腋窝淋巴结，其包膜内有黑色条纹。尽管该病变最初被认为是转移性恶性黑色素瘤，但重新评估显示它是一个良性细胞性蓝痣，区域淋巴结内有良性痣细胞聚集。我们报告此病例以强调细胞性蓝痣如何能模拟恶性黑色素瘤，并提高医生对这种黑素细胞痣良性变体的认识，从而避免不适当的手术和化疗。
