神经源性肿瘤可起于神经的非特异性神经膜、特异性神经膜、神经细胞和嗜铬细胞等不同组织成份。起于非特异性神经膜者为神经纤维瘤,有孤立型与多发型,恶性为神经纤维肉瘤;特异性神经膜即许旺氏神经膜细胞,发生的肿瘤即神经鞘瘤或神经膜瘤,少见恶性;神经细胞可发生神经节细胞瘤或神经节瘤,恶性为成神经节细胞瘤或成交感神经细胞瘤;嗜铬细胞发生嗜铬细胞瘤或付神经节瘤,恶性为成嗜铬细胞瘤。纵隔神经肿瘤还可起于大血管壁内之神经丛。作者报告76例纵隔神经源肿瘤,其中49例起于神经膜,内中神经鞘瘤最多(28例),10例源于神经细胞,4例为其他类型,13例未行手术。在临床上,男女无别,神经鞘瘤平均38岁,神经纤维瘤平
Neurogenic tumors can arise from non-specific neural membranes of the nerves, specific neural membranes, neuronal cells, and chromaffin cells. From the non-specific nerve membrane for the neurofibroma, solitary and multiple hair type, malignant as nerve fiber sarcoma; specific nerve membrane that Schwann cell membrane, the occurrence of tumors that schwannoma or neuroma, rare Malignant; neuronal cells may occur ganglioneuromas or gangliomas, malignant ganglion cell or sympathetic neuroblastoma; pheochromocytoma occurred pheochromocytoma or ganglion tumor, malignant as pheochromocytoma . Mediastinal nerve tumors can also arise from the plexus within the large vessel wall. The authors reported 76 cases of mediastinal neurogenic tumors, of which 49 cases originated in the nerve membrane, the most in the schwannoma (28 cases), 10 cases from the neural cells, 4 cases of other types and 13 cases without surgery. Clinically, both men and women, schwannoma average 38 years old, neurofibroma flat
