As well as being relatively rare, osseous metastases from colorectal cancer are frequently asymptomatic and represent a late manifestation of disease. We report a case of an unidentified, asymptomatic coccygeal metastasis discovered on histological processing of the resection specimen from a patient with locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy followed by radical abdomino-perineal resection with coccygectomy. The anatomical explanation for this finding may involve passage of tumour cells via the vertebral venous plexus.
结直肠癌的骨转移不仅相对罕见，而且常常无症状，代表疾病的晚期表现。我们报告了一例局部晚期直肠癌患者的病例，该患者在接受新辅助放化疗后行根治性腹会阴切除加尾骨切除术，在对直肠肿瘤的切除标本进行组织学处理时发现了一处未识别的、无症状的尾骨转移。这种发现的解剖学解释可能涉及肿瘤细胞通过椎静脉丛转移。
