Giant congenital blue nevus (GCBN) is rare and usually occurs on the scalp. Malignant blue nevus (MBN) is also rare and has a poor prognosis. We report a case of MBN arising in a GCBN on the back. There have been three previous reports of MBN associated with GCBN on the trunk; our case had the earliest onset of MBN arising in a GCBN.
巨大先天性蓝痣(GCBN)较为罕见,通常发生于头皮。恶性蓝痣(MBN)同样罕见,预后较差。我们报告1例发生于背部GCBN的MBN病例。此前有3例关于躯干GCBN合并MBN的报道;我们的病例是MBN在GCBN中发病最早的。
