Giant cell tumor of the tendon sheath (GCTTS) is one of the common tumors of the hand, second only to a simple ganglionic cyst. It can arise from the synovium of joint, bursa, or tendon sheath. Two-thirds of the tumors occur on the volar aspect of fingers. GCTTS in palm is extremely rare. Recurrence of GCTTS is also rare.
We report a 22-year-old female patient who presented to us with palmar swelling on the right hand for 6 years and operated with excision 4 years ago and having a recurrent larger swelling 8 months after the surgery. She was operated with tumor excision supported with marginal excision of the tumor. Follow-up at 1 year showed no recurrence with satisfactory outcome.
GCTTS of the palm is rare. GCTTS recurrences are rarer. This was a recurrence of the rare palmar GCTTS of an unusually large size with secondary contracture which was successfully managed without recurrence and improvement from pre-operative hand functions.
腱鞘巨细胞瘤（GCTTS）是手部常见肿瘤之一，仅次于单纯性腱鞘囊肿。它可起源于关节、滑囊或腱鞘的滑膜。三分之二的肿瘤发生在手指掌侧。手掌部的GCTTS极为罕见。GCTTS的复发也很罕见。
我们报告一名22岁女性患者，右手掌肿胀6年，4年前接受手术切除，术后8个月出现复发且肿胀更大。她接受了肿瘤切除手术，并对肿瘤进行了边缘切除。术后1年随访显示无复发，效果满意。
手掌部的GCTTS罕见。GCTTS复发更为罕见。这是一例罕见的、体积异常大且伴有继发性挛缩的手掌部GCTTS复发，成功治疗后未复发，手部功能较术前有所改善。
