A 38-year-old man was diagnosed with malignant peripheral nerve sheath tumour of the maxilla. He was treated with total maxillectomy. Histopathological examination of the resected specimen revealed a close resection margin. The tumour was of high grade with an MIB-1 labelling index of almost 60%. At six weeks following the surgery, he developed local tumour relapse. The patient succumbed to the disease at five months from the time of diagnosis. The present report underlines the locally aggressive nature of malignant peripheral nerve sheath tumour of the maxilla which necessitates an early therapeutic intervention. A complete resection with clear margins is the most important prognostic factor for malignant peripheral nerve sheath tumour in the head and neck region. Adjuvant radiotherapy may be considered to improve the local control. Future research may demarcate the role of targeted therapy for patients with malignant peripheral nerve sheath tumour.
一名38岁男性被诊断为上颌骨恶性外周神经鞘瘤。他接受了全上颌骨切除术。对切除标本的组织病理学检查显示手术切缘接近。肿瘤为高级别,MIB-1标记指数近60%。术后六周,他出现局部肿瘤复发。该患者在诊断后五个月死于该病。本报告强调了上颌骨恶性外周神经鞘瘤的局部侵袭性,这需要早期治疗干预。切缘清晰的完整切除是头颈部恶性外周神经鞘瘤最重要的预后因素。可考虑辅助放疗以改善局部控制。未来的研究可能会明确靶向治疗在恶性外周神经鞘瘤患者中的作用。
