Colorectal carcinoma usually spreads along predictable routes to the abdominal lymph nodes, liver and lungs. Documented cases of metastatic spread to skeletal muscle are uncommon. To the knowledge of the authors, only four cases have been previously reported in the literature. This is a report of a case of advanced carcinoma of the descending colon with metastases to the left tibialis anterior muscle. This case is unusual in that the patient first presented with a symptomatic secondary deposit and the primary lesion is only discovered after the histology of the left leg tumour is known.
结直肠癌通常沿可预测的途径扩散至腹部淋巴结、肝脏和肺部。有文献记载的转移至骨骼肌的病例并不常见。据作者所知，此前文献中仅报道过4例。本文报告1例降结肠癌伴左胫骨前肌转移的晚期病例。该病例的不同寻常之处在于，患者最初表现为有症状的继发性病灶，且仅在得知左腿肿瘤的组织学结果后才发现原发性病灶。
