Synchronous neoplams are uncommon condition but the incidence is now being increased. The situation is rare when these tumors comes from different origin. We experienced the case with synchronous sigmoid colon cancer and anal squamous cell carcinoma<br>with rectal mucosal metastasis. The patient was 61 years old male. He complained of intermittent hematochezia since 3∼4 months ago. The patient underwent anterior resection for colon cancer and wide excision for anal squamous cell carcinoma. After<br>surgical operation, postoperative adjuvant chemotherapy (5-FU ＋ Leucovorin) and radiotherapy were done. In this case, we could preserve the anal sphincter using combined therapy. We think that this type of management may be useful treatment in patients<br>with colon cancer and anal squamous cell cancer simultaneously.<br>
