对 1 3例上颌窦恶性纤维组织细胞瘤的临床、病理、诊断和预后进行回顾性分析。结果显示上颌窦恶性纤维组织细胞瘤以浸润性生长为主 ,临床主要表现为鼻塞、鼻出血、面颊部麻木肿痛、突眼等 ;容易侵犯鼻腔、筛窦、蝶窦、翼颌窝和眼眶等重要结构 ;容易发生误诊 ;免疫组化检查有助于鉴别诊断。上颌窦恶性纤维组织细胞瘤对放疗不敏感 ,术后容易复发和远处转移 ,预后较差 ,宜尽早行根治性上颌骨切除术。
The clinical, pathological, diagnosis and prognosis of 13 cases of maxillary sinus malignant fibrous histiocytoma were analyzed retrospectively. The results showed that the maxillary sinus malignant fibrous histiocytoma with infiltrative growth, the main clinical manifestations of nasal obstruction, epistaxis, facial numbness and pain, exophthalmos; easy to infringe the nasal cavity, ethmoid sinus, sphenoid sinus, wing and orbital And other important structures; prone to misdiagnosis; immunohistochemistry to help differentiate diagnosis. Maxillary sinus malignant fibrous histiocytoma is not sensitive to radiotherapy, postoperative recurrence and distant metastasis, the prognosis is poor, radical root canal resection should be performed as soon as possible.
