Giant cell tumour of tendon sheath (GCTTS) is a benign, soft-tissue tumour arising from synovial cells of tendon sheaths. Because of the high incidence of recurrence, radical surgical excision is the treatment of choice. Presented here is a rare case of this lesion originating from flexor tendon sheaths of the foot. A 40-year-old Russian white female presented to the clinic with a slightly painful soft tissue mass in her right foot along the medial aspect of her ankle. She gave a one-year history of the mass and was concerned about increasing size, pain, and plantar numbness as well as limitation in her movements to some extent. Interpretation of the magnetic resonance imaging failed to include giant cell tumours in the preoperative differential diagnosis. Considering the proximity of the tumour to important anatomic structures, less radical but grossly complete excision was employed, followed by appropriate periodic re-evaluation. Pedal involvement of GCTTS is rare with a reported predilection for dorsal and lateral localisations around the ankle. Our case presents an unusual occurrence of this tumour with medial localisation of the lesion in the foot, extending through the tarsal tunnel.
腱鞘巨细胞瘤（GCTTS）是一种起源于腱鞘滑膜细胞的良性软组织肿瘤。由于复发率高，根治性手术切除是首选治疗方法。本文介绍了一例罕见的起源于足部屈肌腱鞘的该病变病例。一名40岁的俄罗斯白人女性因右足内踝内侧有一个轻度疼痛的软组织肿块前来就诊。她有该肿块一年病史，担心其大小增大、疼痛、足底麻木以及运动在一定程度上受限。磁共振成像的解读在术前鉴别诊断中未考虑到巨细胞瘤。考虑到肿瘤与重要解剖结构接近，采用了不太根治但大体完整的切除方法，随后进行适当的定期重新评估。GCTTS累及足部罕见，据报道好发于踝关节周围的背侧和外侧部位。我们的病例呈现了该肿瘤在足部病变位于内侧的不寻常情况，并延伸至跗管。
