Rectal neuroendocrine carcinomas constitute <1% of all neuroendocrine carcinomas and <1% of all gastrointestinal tract malignancies. Cutaneous metastases of rectal neuroendocrine carcinoma are rarer than visceral metastases. We represent a 71-year-old man who was diagnosed with neuroendocrine tumor grade 3 originating from the rectum 1 year ago. He was referred for F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for restaging after 6 cycles of chemotherapy and radiotherapy. Intensely increased F-FDG uptake in the right cutaneous inguinal region was consistent with neuroendocrine carcinoma metastasis with biopsy from the same region.
直肠神经内分泌癌占所有神经内分泌癌的比例不到1%，占所有胃肠道恶性肿瘤的比例也不到1%。直肠神经内分泌癌的皮肤转移比内脏转移更为罕见。我们报告一名71岁男性，他于1年前被诊断为起源于直肠的3级神经内分泌肿瘤。在接受6个周期的化疗和放疗后，他因重新分期而接受F-氟脱氧葡萄糖（FDG）正电子发射断层扫描/计算机断层扫描检查。右侧腹股沟皮肤区域F-FDG摄取显著增加，与同一区域活检结果一致，提示为神经内分泌癌转移。
