Metastasis of Rectal Adenocarcinoma to the Clavicle: Report of One Case

Colorectal carcinoma metastases are mostly seen in liver. Almost half of the patients with colorectal cancer have liver metastasis or develop liver metastasis during the disease. Any metastasis outside the liver is rarely seen and if present it is usually seen in lungs brain skin and skeletal system with the same probability. Skeletal metastases mostly involve weight bearing bones. Meanwhile skeletal involvement rarely occurs in clavicle. In this paper we report a case of colorectal cancer metastasis to medial head of clavicle.
