接种疤痕处的基底细胞上皮瘤。

Int J Dermatol. 1978 Nov;17(9):723-5. doi: 10.1111/ijd.1978.17.9.723.

A 42-year-old woman developed a superficial basal cell epitheliol in a smallpox vaccination scar. After reviewing similar reports in the English literature, I believe any unusual change occurring in a vaccination scar, either simultaneously or years later, should be viewed as a possible malignancy and treated accordingly.

一名42岁女性在天花疫苗接种疤痕处出现了浅表性基底细胞上皮瘤。在查阅英文文献中的类似报告后，我认为接种疤痕处同时或多年后出现的任何异常变化都应被视为可能的恶性病变并相应进行治疗。
