Perineuriomas (PNs) are soft tissue tumors originating from the perineurium. We report the case of a 51-year-old man who presented with a right mandibular mass. Initial examination revealed a palpable, painless, solid mass at the right mandibular angle. Preoperative computed tomography revealed a highly absorbent mass with uneven staining margins in contact with the mandible. Surgery was performed under general anesthesia for diagnosis, and a well-defined solid tumor of 8 cm was excised. Subsequently, immunohistological staining revealed that the tumor was diagnosed with perineuriomas recurrence of mental nerve origin. This is the first report on perineuriomas of mental nerve origin and the third report on recurrent perineuriomas. Our findings highlight the need for immunohistological staining of tumors for perineuriomas diagnosis, and follow-up observation might be recommended given the risk of recurrence.
神经束膜瘤(PNs)是起源于神经束膜的软组织肿瘤。我们报告一例51岁男性患者,其表现为右下颌肿块。初步检查发现右下颌角处有一个可触及的、无痛的实性肿块。术前计算机断层扫描显示一个高吸收性肿块,其染色边缘不均匀,与下颌骨接触。在全身麻醉下进行手术以明确诊断,切除了一个边界清晰的8厘米实性肿瘤。随后,免疫组织化学染色显示该肿瘤被诊断为精神神经源性神经束膜瘤复发。这是关于精神神经源性神经束膜瘤的首例报告,也是关于复发性神经束膜瘤的第三例报告。我们的研究结果强调了对肿瘤进行免疫组织化学染色以诊断神经束膜瘤的必要性,鉴于复发风险,可能建议进行随访观察。
