Abstract
Four cases of intramuscular metastasis of carcinoma are reported. The preoperative clinical diagnosis of all four cases was soft-tissue sarcoma. Definitive diagnoses, made by open biopsy, were uterine carcinoma, gastric carcinoma, lung carcinoma, and hypopharyngeal carcinoma. All patients died from lung, liver, or brain metastasis several months after open biopsy despite surgery, chemotherapy, or radiation therapy. Case reports of macroscopic metastases to muscle are rare, and the authors report four such cases experienced during a 15-year period.
