Tenosynovial giant cell tumor (TGCT) is a group of rare, typically non-malignant tumors of the joints. TGCT tumors often develop from the lining of joints (also known as synovial tissue).[1][2][2]: 100 [3][3]: 245 .
Common symptoms of TGCT include swelling, pain, stiffness and reduced mobility in the affected joint or limb.[2]: 102 This group of tumors can be divided into different subsets according to their site, growth pattern, and prognosis.[4][4]: 361 Localized/nodular TGCT is sometimes referred to as giant cell tumor of the tendon sheath;[2]: 100 diffuse TGCT is also called pigmented villonodular synovitis (PVNS).[2]: 102 These two distinct subtypes determined by radiographic appearance.[5] Localized TGCT is defined as a well circumscribed tumor while diffuse TGCT exhibits a locally aggressive and infiltrative behavior.[6]
