[A case of multiple skin metastases from cancer of the descending colon responding to FOLFIRI/cetuximab therapy].

A 64-year-old woman presented to our hospital with subcutaneous tumors in the right thoracic region. After undergoing a thorough medical evaluation, she was diagnosed with multiple skin metastases arising from cancer of the descending colon. Surgical resection of the primary lesion was performed and FOLFIRI (5-fluorouracil, levofolinate calcium, irinotecan) and cetuximab chemotherapy for the metastases was initiated. The patient subsequently entered remission and did not experience any major side effects. This case report details an effective therapy for colon cancer with multiple skin metastases and presents a discussion of the expression profiles of epidermal growth factor receptor in both the primary and metastatic lesions.
