Giant cell tumour of tendon sheath (GCTTS) – 2 Most common tumour of hand after ganglion cyst

Probably one of the most common benign neoplasm in the human hand, the Giant Cell Tumour of Tendon Sheath (GCTTS) has been studied by many authors over the years as a popular tumour. There have been studies on the etilogical factors, however, limited attention has been given to etiology, prognostic factors, and recurrence rate. Because there are several factors that predispose to recurrence, it is imperative that medical practitioners ensure complete excision of the tumour, including removal of residual satellite nodules. This study is a focus on 0.5cm swelling over dorsal part of the interphalangeal joint of middle finger of the right hand of a 55-year old female that was initially unilobulated, which eventually increased to 3cm and was bilobed over 6 months. With meticulous dissection and the use of magnification loupe to obtain a low recurrence rate, thereby emphasising the key role of surgery as the first prognostic factor of GCTTS.
