Facial skin metastasis of colorectal cancer: a case report

Introduction Liver and lungs are common locations of distant metastases of colorectal cancer. Skin metastases of colorectal cancer are very rare, and facial lesions are extremely uncommon. Case presentation An anterior resection of the rectum was performed for rectal cancer T3N0M0G3. A small ulcer on the upper lip developed 3.5 years after primary operation. Metastasis of adenocarcinoma was confirmed histologically, and local excision was performed. At the same time, a solitary metastasis in the right lung was diagnosed, and the right lower lobectomy was performed. No other metastasis or local recurrences were observed during the next 7 months. Conclusion Skin metastases in the face from colorectal cancer are very rare and may indicate tumour relapse several years after primary resection. These patients have a worse prognosis.
