Abstract
Background:Tendon sheath giant cell tumor（GCT-TS） is an extremely rare tumor with highly nonspecific symptoms. It usually originates in the tendon sheath and periarticular soft tissue of the facet joint. Rarely involve the large joints that occur around the knees, ankles, elbows, and hip joints. The benign but aggressive disease progresses slowly. However, it can eventually lead to irreversible damage to the joint. Cace presensent: we briefly describe a misdiagnosed case of a giant cell tumor of the unilateral tendon sheath of the ankle joint. A 77-year-old man developed swelling in his ankle, which though mild, affected his walking gait and quality of life. At present, Conclusion:giant cell tumor of tendon sheath of ankle joint is very rare, and its clinical manifestations are not obvious, and it is often easy to be wrongly diagnosed. MRI is the best examination method to determine the scope of soft tissue destruction, and pathological examination is the most important means to diagnose giant cell tumor of tendon sheath at present.
Highlights
Tendon sheath giant cell tumors (GCT-Ts) are benign, slow-growing tumors that are caused by the tendon sheath of the joint and surrounding soft tissue
The exact histopathology of the tumor remains controversial, and it may appear as a tumor or as a massive reactive proliferation.GCT-Ts have been classified as fibrohistiocytic neoplasms by the World Health Organization (WHO) [1]
We describe a case of GCT-TS in the ankle joint, an extremely rare tumor that is managed by surgical excision
