We describe a case of intramuscular metastasis in the thigh as an initial manifestation of rectal cancer, and review the previously reported 11 cases of skeletal distant metastasis from colorectal cancer. The patient was a 44‐year‐old man suffering from an increasingly painful mass in his left thigh. Magnetic resonance imaging showed an irregularly accentuated mass within the quadriceps femoral muscle, measuring 9 × 4 cm in size. The patient underwent an en bloc wide resection of the tumor, which was confirmed to be metastatic cancer which was diffusely positive for cytokeratin on immunohistochemistry. Further investigations revealed 3 cm‐sized primary rectal cancer with multiple liver metastases. Despite giving adjuvant chemotherapy, the patient died 6 months after the surgery. We should keep in mind that intramuscular metastasis may rarely occur as an initial manifestation of colorectal cancer when we encounter a patient with an undiagnosed intramuscular mass.
