A schwannoma is a rare benign tumour of peripheral nerve origin. We present a case of a 65-year-old woman with a 1-year history of a slowly enlarging, painless and movable mass, palpable by fingers in her right lower eyelid, adjacent to the inferior orbital rim. No apparent mass was present by macroscopic examination. A subciliary incision and blunt dissection through the septum revealed a pearl-like round and encapsulated cystic mass between the fat pads just below the septum. A total excision of the tumour was performed. Histopathology and immunohistochemistry led to the diagnosis of schwannoma. Although rare, schwannoma should be considered in the differential diagnosis of well-capsulated masses in the periorbital region.
神经鞘瘤是一种罕见的起源于周围神经的良性肿瘤。我们报告一例65岁女性病例，其右下眼睑有一个缓慢增大、无痛且可移动的肿块，已有1年病史，该肿块可通过手指触及，位于眶下缘附近。肉眼检查未发现明显肿块。通过睑缘下切口并钝性分离穿过隔膜，发现在隔膜下方的脂肪垫之间有一个珍珠样圆形且有包膜的囊性肿块。对肿瘤进行了完整切除。组织病理学和免疫组织化学检查确诊为神经鞘瘤。尽管罕见，但在眶周区域有包膜的肿块的鉴别诊断中应考虑神经鞘瘤。
