Giant-cell tumor of the tendon sheath (GCT-TS) is an uncommon occurrence for a foot and ankle surgeon. However, there is a need to recognize the symptoms of typical and atypical presentations of this pathology. These benign neoplasms are recognized clinically as a soft-tissue mass that is usually painless and palpable. The foot and ankle account for only 3% to 5% of all GCT-TS in the body, with most being located in the hand. Giant cell tumor in the tendon sheath occurring in the foot and ankle is usually encountered on the lateral ankle and dorsum of the foot, occupying the extensor tendons. Additionally, it is commonly misdiagnosed clinically. This case study illustrates how early use of magnetic resonance imaging decreased patient morbidity with early recognition and excision of GCT-TS.
腱鞘巨细胞瘤（GCT-TS）对于足踝外科医生来说并不常见。然而，有必要认识到这种病理状况典型和非典型表现的症状。这些良性肿瘤在临床上被认为是一种通常无痛且可触及的软组织肿块。足踝部的腱鞘巨细胞瘤仅占全身所有腱鞘巨细胞瘤的3%至5%，大多数位于手部。发生在足踝部腱鞘的巨细胞瘤通常出现在外踝和足背，累及伸肌腱。此外，它在临床上常被误诊。本病例研究说明了早期使用磁共振成像如何通过早期识别和切除腱鞘巨细胞瘤降低患者的发病率。
