Merkel cell tumor (MCT) typically occurs on the head or neck of elderly patients. A case is presented of a teenage girl with an MCT on her toe. The diagnosis was made 5 years after an ingrown nail on the toe was avulsed. During the interim 5 years, the periungual skin looked like granulation tissue and thus no biopsy was performed. This case of MCT is unique in three aspects: (a) extraordinarily young age, (b) atypical site, and (c) deceptive clinical appearance. Awareness of the possible occurrence of MCT in younger patients and in unusual locations will facilitate earlier diagnosis.
默克尔细胞癌（MCT）通常发生在老年患者的头部或颈部。本文报告一例青少年女孩脚趾部患默克尔细胞癌的病例。该诊断是在脚趾嵌甲被拔除5年后做出的。在这中间的5年里，甲周皮肤看起来像肉芽组织，因此未进行活检。该默克尔细胞癌病例在三个方面具有独特性：（a）年龄极小，（b）部位不典型，（c）临床外观具有迷惑性。认识到年轻患者和不寻常部位可能发生默克尔细胞癌将有助于早期诊断。
