Giant cell tumour of tendon sheath is a benign soft tissue tumour arising from the tendon sheath. The involvement of foot and ankle by such tumours is relatively rare. Children are not commonly afflicted by this condition. All such tumours are reported to arise either from a single tendon sheath or one joint. We report a case of giant cell tumour of tendon sheath in a 12-year-old child, arising simultaneously from the tendon sheaths of tibialis posterior and flexor digitorum longus tendons, as well as extending into the ankle joint. It was treated by complete excision of the mass along with the tendon sheaths with reconstruction of the flexor retinaculum. The location of the tumour, age of the patient, diffuse nature of the tumour and novel technique of reconstruction of the flexor retinaculum make this case extremely rare and the first to be reported in literature.
腱鞘巨细胞瘤是一种起源于腱鞘的良性软组织肿瘤。这种肿瘤累及足踝部相对少见。儿童很少患此病。据报道，所有此类肿瘤均起源于单个腱鞘或一个关节。我们报告一例12岁儿童的腱鞘巨细胞瘤，该肿瘤同时起源于胫后肌腱和趾长屈肌腱的腱鞘，并延伸至踝关节。通过完整切除肿物及腱鞘并重建屈肌支持带进行治疗。该肿瘤的位置、患者年龄、肿瘤的弥漫性以及屈肌支持带重建的新技术使得此病例极为罕见，且为文献首次报道。
