Patellar metastasis from a large bowel adenocarcinoma

Although bone tumors are often located in the knee area, primary tumors of the patella are rare (6, 8), and patellar metastases even rarer. A few cases were reported in the literature, originating from the breast, lung, kidney, uterine cervix and oesophagus. We report a case, for the first time to our knowledge, of a patellar metastasis from a large bowel carcinoma.
