Schwannomas (neurilemomas) are encapsulated tumours made entirely of benign neoplastic Schwann cells. They are the most common tumour of peripheral nerves, but very uncommon in gynaecologic practice.
The objective is to demonstrate unusual histology mimicking schwannoma in a case of leiomyoma in a woman who had a history of vaginal hysterectomy.
We report a case of a 50-year-old hysterectomised patient who was referred with complaints of dull pain in the left inguinal region of the abdominal cavity during the last 3 months. The narrated surgical video article demonstrates the dissection of the left parametrium, tumour removal, colpotomy, specimen extraction, and vaginal laparoscopic suturing. Pre-operative CT-scan images of the pelvis with retroperitoneal tumour and macroscopic and histological views of the schwannoma are also provided.
Full recovery of the patient after laparoscopic removal of the tumour.
As a result of the surgical treatment, the patient recovered fully.
Schwannoma-like leiomyomas are rare tumours. They can be extra peritoneally located, without any connection to the uterus and adnexa. They are difficult to diagnose before surgery. The laparoscopic approach is the best option for the treatment of such rare extra organic tumours.
施万细胞瘤（神经鞘瘤）是完全由良性肿瘤性施万细胞构成的包膜性肿瘤。它们是周围神经最常见的肿瘤，但在妇科实践中非常罕见。
目的是在一名有阴道子宫切除术病史的女性平滑肌瘤病例中展示模仿施万细胞瘤的不寻常组织学表现。
我们报告一例50岁接受子宫切除的患者，她在过去3个月中因腹腔左侧腹股沟区钝痛前来就诊。所叙述的手术视频文章展示了左侧子宫旁组织的解剖、肿瘤切除、阴道切开术、标本取出以及阴道腹腔镜缝合。还提供了盆腔伴有腹膜后肿瘤的术前CT扫描图像以及施万细胞瘤的大体和组织学图像。
腹腔镜切除肿瘤后患者完全康复。
手术治疗后，患者完全康复。
类施万细胞平滑肌瘤是罕见肿瘤。它们可位于腹膜外，与子宫和附件无任何关联。术前难以诊断。腹腔镜手术是治疗此类罕见的器官外肿瘤的最佳选择。
