Schwannoma is a benign tumour of Schwann cells originating from myelin sheath of axons of the nerves. It is usually seen in the vestibular region, very rarely found in extremity regions. Schwannomas are termed 'Giant' when they measure more than five centimetres in a minimum of one dimension. Giant schwannomas in the foot and ankle region are extremely uncommon. Only eight cases of such a condition are reported. This is a case report of a giant schwannoma found arising from the superficial peroneal nerve in the dorsolateral aspect of the foot. This swelling was excised completely and the diagnosis was confirmed by histopathology.
神经鞘瘤是一种起源于神经轴突髓鞘的雪旺氏细胞的良性肿瘤。它通常见于前庭区域，在四肢区域非常罕见。当神经鞘瘤在最小的一个维度上超过五厘米时，被称为“巨大”。足部和踝关节区域的巨大神经鞘瘤极为罕见。只有 8 例报告了这种情况。这是一例发生在足部背外侧浅层腓总神经的巨大神经鞘瘤病例报告。该肿块被完全切除，通过组织病理学证实了诊断。
