Ancient schwannomas are a rare variation of schwannomas, with the distinction being based on histopathological examination of the excised specimen. On histopathological examination, ancient schwannomas exhibit degenerative changes such as calcification, hyalinization, and cystic necrosis, along with S100 positivity. Complete surgical excision is the mainstay treatment for ancient schwannomas and carries a favorable prognosis. Recurrence is the most common complication, often arising from incomplete surgical excision. Herein, we present a case of a 41-year-old male who presented to our center as a case of a retroperitoneal mass for further investigations and diagnostic workup. Imaging showed a retroperitoneal mass in the right iliac fossa. We proceeded with ultrasound guided needle biopsy, and examination of the specimen confirmed the diagnosis of ancient schwannoma. Subsequently, the patient underwent surgery, and complete surgical excision was achieved. On follow-up 3-months later, the patient is doing well, and no signs of recurrence were found.
陈旧性神经鞘瘤是神经鞘瘤的一种罕见变异类型，其区分基于对切除标本的组织病理学检查。在组织病理学检查中，陈旧性神经鞘瘤表现出诸如钙化、玻璃样变性和囊性坏死等退行性改变，同时S100呈阳性。完整手术切除是陈旧性神经鞘瘤的主要治疗方法，预后良好。复发是最常见的并发症，通常源于手术切除不完全。在此，我们报告一例41岁男性患者，该患者以腹膜后肿块病例的形式到我们中心进行进一步检查和诊断评估。影像学检查显示右髂窝有一腹膜后肿块。我们进行了超声引导下针吸活检，对标本的检查确诊为陈旧性神经鞘瘤。随后，患者接受了手术，并实现了完整切除。3个月后的随访中，患者情况良好，未发现复发迹象。
