Facial cutaneous metastasis of colorectal adenocarcinoma.

Facial cutaneous metastasis from carcinoma is a rare and late clinical finding that is associated with disseminated disease and a poor prognosis. Skin metastases predominantly originate from primary tumours of the lung and melanoma. Skin metastases from colon tumours occur in only 4-6.5% of cases of metastatic colorectal cancer. They are most often located on the abdominal skin. We present an unusual case in which a primary colorectal adenocarcinoma metastasised to the face. This cutaneous lesion occurred 4 years after diagnosis of the primary tumour. This case highlights the importance of prompt investigation of new or evolving skin lesions in patients with a history of malignancy. Early detection and initiation of treatment may prevent development of widespread skin metastases and extend life expectancy.
