Schwannoma is a benign, solitary, slow-growing neoplasm of the peripheral nerve sheath. These tumors are rarely found in the external genital system, and only a few cases of vulvar schwannoma have been reported. Herein, we report a case of a vulvar schwannoma. A 37-year-old woman presented with a 3-cm-sized painless mass of the vulva which had been present for 3 years. Magnetic resonance imaging (MRI) of the pelvis showed an isolated finding of a 4.6-cm-sized round mass with a well-defined margin in the midline vulvar area. Simple excision of the tumor was undertaken, and histological examination with immunohistochemical testing demonstrated a vulvar schwannoma. Although benign schwannoma only rarely occurs in the vulva and other external areas of female genitalias, we suggest that it should be considered a differential diagnosis for patients that present a vulvar enlargement or mass. Simple surgical resection and follow-up is the most convenient treatment.
神经鞘瘤是一种起源于周围神经鞘的良性、孤立性、生长缓慢的肿瘤。这些肿瘤在女性外生殖器系统中很少见，仅有少数外阴神经鞘瘤的病例报道。在此，我们报告一例外阴神经鞘瘤。一名37岁女性，外阴出现一个3厘米大小的无痛性肿块，已存在3年。骨盆磁共振成像（MRI）显示，在外阴中线区域有一个孤立的4.6厘米大小的圆形肿块，边界清晰。对肿瘤进行了单纯切除，组织学检查及免疫组化检测证实为外阴神经鞘瘤。尽管良性神经鞘瘤很少发生于外阴及女性生殖器的其他外部区域，但我们建议，对于出现外阴肿大或肿块的患者，应将其纳入鉴别诊断范围。单纯手术切除及随访是最简便的治疗方法。
