Tenosynovial Giant Cell Tumor (Tgct) of Hip- A Rare Case Report

Tenosynovial giant cell tumor (TGCT) is a relatively rare inammatory disease that affects the joint synovium, bursae, and tendon sheaths, leading to nonspecic, often insidious discomfort in the joints. Surgery, with or without adjuvant radiation, is the primary therapy option for tenosynovial giant cell tumor. Here is a report of a case of a 40 year old male presented with symptoms of pain and limp over right leg since 8month. Radiological assessment showed secondary arthritis of right hip with features of avascular necrosis (AVN). Considering clinical and radiological features the patient was planned for uncemented total hip replacement (THA).Intra operatively we observed unusual synovial hypertrophy with yellowish/gray discoloration. Total synovectomy was done and proceded with uncemented THA as per plan. The synovium was sent for histopathological assessment which showed partially encapsulated tumor cells. Post operatively course was uneventful and rehabilitation was done as per standard protocols. Patient is being followed up regularly till date and 6months follow up did not show any signs of recurrence.This observation left us with a conclusion that complete excision of lesion combined with THA can be an effective treatment for Giant cell tenosynovitis.
