Synovial chondromatosis is a condition where small, cartilage-like nodules develop in the lining of a joint, usually in the knee, hip, or shoulder. These nodules can break off and float around in the joint, which might cause pain, swelling, or limited movement. The exact cause isn’t well understood, but it’s not cancerous. Treatment often involves removing the nodules through surgery to relieve symptoms and improve joint function.

There was a recent re-classification of pigmented villonodular synovitis (PVNS) to Tenosynovial giant cell tumor (TGCT). TGCT/PVNS is a rare condition that affects the lining of joints, especially the knee. It causes the lining to thicken and form nodules (nodular form) or may thicken the lining throughout the joint (diffuse form). The thickening can be brownish in color due to pigment. TGCT/PVNS can lead to joint pain, swelling, and stiffness. While TGCT/PVNS isn’t cancerous, it can be aggressive and may come back after treatment. Surgery is often the mainstay of management. However, there have been recent advances in medical management of this lesion, and we will have a discussion with you to develop a comprehensive treatment plan that aligns with your goals.

A myxoma is a type of benign (non-cancerous) tumor that can appear in the soft tissues of the arms or legs. These masses have a high water content and a gellike consistency. Treatment usually involves surgical removal of the mass.
