Schwannomas are rarely seen in the foot and ankle and mostly arise from the plantar aspect. Dorsal foot schwannomas are not commonly reported. We describe the case of a 25-year-old man who had a painful swelling on the dorsum of his right foot, which resembled a ganglion cyst on clinical examination and ultrasonography findings. Persistent symptoms prompted the need for an excisional biopsy, which revealed a benign schwannoma arising from the medial dorsal cutaneous nerve. Complete and careful excision relieved the symptoms without causing any distal neural deficit. Thus, schwannomas can mimic as a ganglion cyst. Excisional biopsy of such swellings, if symptomatic, helps in confirming the diagnosis, and provides a good functional outcome.
神经鞘瘤在足踝部很少见，且大多起源于足底。足背神经鞘瘤的报道并不常见。我们描述了一名25岁男性的病例，他的右脚背出现疼痛性肿胀，临床检查和超声检查结果类似腱鞘囊肿。持续的症状促使需要进行切除活检，结果显示为起源于足背内侧皮神经的良性神经鞘瘤。完整且仔细的切除缓解了症状，未导致任何远端神经功能缺损。因此，神经鞘瘤可表现为腱鞘囊肿。对于此类有症状的肿胀进行切除活检有助于确诊，并能带来良好的功能预后。
