A case of multiple subcutaneous lower leg metastases in a colon cancer patient

Abstract

A 76-year-old woman underwent surgery for ascending colon cancer. On pathology, a poorly differentiated adenocarcinoma, pSE, pN0, M0, ly2, v1, pStage II was diagnosed. Subsequently, 2 months after the operation, multiple subcutaneous tumors were noted predominantly in the lower legs. Most were resected ; on pathology, they were found to be colon cancer metastases. PET done 1 year after the first operation only revealed subcutaneous and skin metastases. However, 20 months after the first operation, the patient died as a result of other distant metastases. Subcutaneous metastasis in the lower legs of colon cancer patients is very rare. Therefore, we report this case with a review of the literature.
