Synovium is a rare site of metastasis for solid tumors. Only 50 cases of synovial metastasis from solid tumors have been previously reported in literature. While the knee is the most common target, most common histological type of the primary is adenocarcinoma and the lung is the most common site of the primary (12 cases). In this article we present two cases of synovial metastasis from non-lung primaries as one patient with bladder cancer and the other patient with colon cancer.
