Giant cell tumour of the tendon sheath (GCTTS) commonly presents as a slow-growing and painless soft-tissue lesion in the hand. It has a propensity to mimick other benign and malignant lesions of the hand including lipoma, haemangioma, myxoid cyst, synovial sarcoma, aneurysmal bone cyst, fibroma and osteosarcoma. GCTTS has a unique histopathological appearance that aids in definitive diagnosis. Although bony invasion and local aggressive characteristics have only been reported rarely, the treatment of choice is local excision. The following case illustrates a fairly typical presentation of GCTTS with certain atypical features.
腱鞘巨细胞瘤（GCTTS）通常表现为手部缓慢生长且无痛的软组织病变。它容易模仿手部的其他良性和恶性病变，包括脂肪瘤、血管瘤、黏液样囊肿、滑膜肉瘤、动脉瘤样骨囊肿、纤维瘤和骨肉瘤。GCTTS具有独特的组织病理学表现，有助于明确诊断。尽管骨侵犯和局部侵袭性特征仅有罕见报道，但首选的治疗方法是局部切除。以下病例说明了GCTTS一种具有某些非典型特征的相当典型的表现。
