Mucinous transformation of synovium.
A unique case of mucinous transformation of knee joint synovium associated with recurrent mucinous joint effusions and severe osteoarthritis is presented. The lesion probably represented an extreme pathologic expression of physiologic synoviocytic synthesis of hyaluronic acid. It did not appear to be related to other myxoid lesions that may occur in this area.
