An 89-year-old woman had three tumors of several years' duration in a stepping-stone distribution on the dorsum of her right foot. The two larger ones were diagnosed histologically as eccrine porocarcinomas, and the smallest of the three shared many clinical similarities with them. Eccrine porocarcinoma is a rare malignant tumor. We describe this peculiar case in which three tumors developed in the same region and discuss how they might have occurred. It is most likely that the three tumors of this case originated from nevoid tumors, and that the individual lesions exhibited malignant changes.
一名89岁女性的右脚背有3个持续数年的肿瘤，呈阶梯状分布。其中两个较大的肿瘤经组织学诊断为小汗腺汗孔癌，三个肿瘤中最小的一个与它们有许多临床相似之处。小汗腺汗孔癌是一种罕见的恶性肿瘤。我们描述了这个在同一区域出现3个肿瘤的特殊病例，并讨论了它们可能的发生方式。该病例中的3个肿瘤很可能起源于痣样肿瘤，且各个病变呈现出恶性变化。
