Tenosynovial giant cell tumor (TGCT) is a non-malignant tumor defined histologically as inclusions of “osteoclast-like” multinucleated giant cells, hemosiderin, and macrophages. [1] This histology can present one of 2 clinically distinct ways. TGCT tumors often develop from the lining of joints (also known as synovial tissue).
A number of tumors have giant cells, but are not true benign giant-cell tumors. These include aneurysmal bone cyst, chondroblastoma, simple bone cyst, osteoid osteoma, osteoblastoma, osteosarcoma, giant-cell reparative granuloma, Giant-cell tumor of the tendon sheath and brown tumor of hyperparathyroidism.

A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath. [3] It most often occurs at the back of the wrist, followed by the front of the wrist. [3] [4] The cause is unknown. [3] The underlying mechanism is believed to involve an outpouching of the synovial membrane. [4] Diagnosis is typically based on examination.
Fibroma of tendon sheath is a benign tumor that presents as a small subcutaneous nodule that slowly increases in size. [1] This is a notably uncommon condition. According to case report literature, the tumors often have a multinodular growth pattern, with individual nodules being composed of bland, slender, spindle-shaped cells (myofibroblasts) in a dense, fibrous matrix.” [2] A common ...

The name "synovial sarcoma" was coined early in the 20th century, as some researchers thought that the microscopic similarity of some tumors to synovium, and its propensity to arise adjacent to joints, indicated a synovial origin; however, the actual cells from which the tumor develops are unknown and not necessarily synovial.

A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [ 1 ] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause, occurring in 19–39% of cases. Less frequently, it results from some malignant tumors, such as osteosarcoma, chondrosarcoma, and ...
