Neurogenic tumors of the nasalcavity and paranasal sinuses arerelatively rare. Seven cases arepresented. Of them, 4 were benign(3 neurilemoma and 1 neurofibroma)and 3 were malignant (1 neurofibro-sarcoma and 2 olfactory neuroblasto-ma). All patients with benign neuro-genic tumors in this series had a his-tory of recurrent epistaxis and uni-lateral nasal obstruction for 7 monthsto 5 years, while those with malignanttumor had symptoms less than 6 months. The gross appearance of neuro-genic tumor in nasal cavity was similarto that of a bleeding polyp, but moreindurated and firm. When the tumorcontinued to grow it might cause de-formation of the nose and in case ofa malignant tumor erosion and destruc-tion of the neighboring bones wereusually observed on roentgenogram.Diagnosis was confirmed by biopsy. The result of complete excision ofbenign, neurogenic tumor was satisfac-tory. In malignant ones, such as olfac-tory neuroblastoma and neurofibrosar-coma, radiotherapy following surgicalexcision was needcd.

文本报告7例少见的鼻腔和鼻窦神经源性肿瘤。对其临床及病理特点、治疗及预后等方面进行了简要讨论。根据本组治疗经验对神经纤维瘤和神经鞘膜瘤等良性肿瘤手术切除效果良好,而恶性者如嗅神经母细胞瘤单独手术效果不佳,应以手术加放疗效果较好。

From Jan.1965 to Dec.1985, 205 cases of mediastinal tumors and cysts treated by surgery are reported.All patienta were operated upon and the diagnosis was confirmed by histopathology.The incidence of neurogenic tumors was 26.8%, thymic tumors 20.4%, and teratoid tumors 19.6%. In this Series, 64 patients (31.2%) were Symptom-free, the tumors were discovered accidently in routine chest examination.The patients who had obvious symptoms were more likely to be malignant than benign. Surgical approaches for the excision of mediastinal tumors and cysts should be individualized.The intercostal or median sternotomy route for anteriorly located lesions facilitates the resection by better expoure.In four patients, their neurofibromas were too big to be removed through conventional dorsal approach, thereby, the dorsal approach combined with thorocotomy was used and gave good result.The result showed that surgical treatment for myasthenia gravis complicating thymoma may give some benifits. The diagnosis and operative experiences were also discussed in this paper.

本文报告了我科自1965年~1985年间收治的205例纵隔肿瘤,所有病例均经病理诊断证实。最常见的三种纵隔肿瘤为神经原性肿瘤(26.8%),胸腺肿瘤(20.5%)和畸胎性肿瘤(19.5%)。纵隔肿瘤的常见症状有胸闷、胸痛、咳嗽等,有明显临床症状者多为恶性病变。纵隔肿瘤的手术切口因人而异,前胸切口对前纵隔肿瘤有暴露好、操作容易等优点,对明显突入胸腔的哑铃状神经纤维瘤可经背部及后外侧胸部切口一期手术切除。手术切除率为87.3%,手术死亡率为0.9%。未能切除者多为恶性病变(其中包括2例罕见的原发纵隔精原细胞瘤)。本文还对诊断及手术要点进行了讨论。

5 cases of familial nenrofibromatosis were reported. The chest manifestations were atre ssed : (1)thin and twisted ribs; (2)interstitial pulmonary fibrosis, (3)mediastinum neurogenic tumors; (4)heart abnormalities.The abonrmalities of some part of trunk bones and differential diagnosis were discussed.

本文报道了家族性神经纤维瘤病5例,着重讨论了本病较少见的胸部X线改变,主要表现为:(1)胸廓畸形及部分肋骨纤细扭曲;(2)肺间质纤维变;(3)纵膈神经源性肿瘤;(4)心脏改变。并述及其它部分骨的异常X线改变和有关的鉴别诊断。
