Background Facial skin metastases from colorectal cancer are extremely rare and appear several years after resection of the primary tumour. They are an important finding, often being the first sign of metastasis from a previously treated colon cancer. Case presentation We describe a case of a 69 year old patient with cutaneous metastasis to the chin from a previously treated adenocarcinoma of the colon. The patient presented with dyspnoea, pleuritic pain and loss of weight. A chest x-ray revealed a right upper lobe mass of the lung which on subsequent surgical exploration proved to be metastatic from colorectal adenocarcinoma resected three years ago. During the postoperative course, a nodule was noted on the chin and excision biopsy revealed it was also a metastasis from the initial colorectal cancer. Palliative chemoradiotherapy was administered and the patient survived 8 months. Conclusion High index of suspicion is necessary for the early detection of facial cutaneous metastases from colorectal cancer. The aim is to start treatment as soon as possible before widespread visceral metastases occur. Cutaneous metastases from colorectal cancer carry a better prognosis in comparison to those of other epithelial tumours.
