Grouped patterns of pigmented lesions are infrequent. Of the several reports of agminated nevi, most have been Spitz nevi or blue nevi. The distribution of these nevi is often segmental, following a dermatome or the lines of Blaschko. Most segmental nevi are not agminated and develop early in childhood [1]. We describe a rare case of congenital agminated segmental nevi on the chest.
色素沉着性皮损的群集模式并不常见。在几篇关于聚合性痣的报道中，大多数为斯皮茨痣或蓝痣。这些痣的分布通常呈节段性，沿皮节或布拉斯科线分布。大多数节段性痣并非聚合性，且在儿童早期就已出现[1]。我们描述了一例胸部先天性聚合性节段性痣的罕见病例。
