Merkel cell tumour is a rare malignant cutaneous neoplasm of neuroendocrine origin. It mainly affects women over 50, is generally located in photo-exposed areas, is normally asymptomatic and of rapid growth. It has a high percentage of recurrences and metastasis, with the most frequent sites of dissemination being the skin, followed by the regional lymph nodes. Its treatment is still controversial. We report a clinical case of a 76-year-old woman with erythematous nodule in the right forearm that was not responding to treatment. The final diagnosis was a Merkel tumour and after the treatment it shows good progress.
默克尔细胞癌是一种罕见的神经内分泌起源的恶性皮肤肿瘤。它主要影响50岁以上的女性，通常位于暴露于阳光的部位，一般无症状且生长迅速。它的复发和转移率很高，最常见的扩散部位是皮肤，其次是区域淋巴结。其治疗方法仍存在争议。我们报告一例临床病例，一名76岁女性右前臂出现红斑结节，治疗无效。最终诊断为默克尔细胞瘤，治疗后病情进展良好。
