ABSTRACT: Two cases are presented of
patients with a history of metastatic rectal adenocarcinoma presenting with a
painful joint effusion. Both cases are potential examples of metastasis to
periarticular bone with local infiltration to the synovium, which is one
proposed mechanism of intrasynovial metastasis. While skeletal metastases are a
relatively common occurrence in metastatic adenocarcinoma, intraarticular
metastasis is extremely rare. These cases highlight the need to consider
metastasis in the differential of joint swelling in the setting of a history of
adenocarcinoma.
