周围神经鞘瘤(附26例分析)

大多数周围神经的肿瘤都是Schwann细胞活跃增殖的结果。神经鞘瘤是一种良性孤立性有包膜的特殊类型肿瘤。本文报告我院近10年手术切除及病检确诊的26例(良性22例,恶性4例)神经鞘瘤。由于本瘤较罕见,故术前只2例诊断正确。18例(70％)随访平均62个月。4例(良性3例,恶性1例)于术后短期内复发,均因治疗过晚或已有恶变,或与未能彻底切除有关。虽文献介绍神经鞘瘤基本上都是良性,但本组4例(15.4％)恶变。故作者建议应将此瘤看作是有潜在恶变可能的良性瘤,最好尽早手术切除。

NEURILEMOMMA OF PERIPHERAL NERVES

Most tumors of peripheral nerves are the result of proliferation of the active and versatile Schwann cells and sheath nerve fibers. A neurilemomma is considered as a specific type of benign solitary encapsulated nerve sheath tumor. This paper presents 26 cases which had been excised and diagnosed by clinical and pathological exminations with in the past 10 years in arthers' hospital. Because this tumor is relatively rare, only 2 cases had been accurately diagnosed before operation. Follow-up of 18 cases showed 4 cases recurred, due to incomplete extirpation, owing to that the tumor was too exensive or alieady had had malignant changes. Although neurilemomma is essentially benign in behavior as stated in documents but there were 4 cases undergome malignant changes this series. So the authers recommend that a neurilemomma should be regarded as a potential malignant tumor, and should be radically excised as early as possible.
