摘要
对68例胸腺瘤从临床、病理及X线等方面进行分析,其中良性44例,恶性24例。结果发现:良性胸腺瘤合并重症肌无力较常见(占77.3％),而恶性胸腺瘤出现胸痛者较多(占20.8％)。X线及手术所见:恶性胸腺瘤多数体积较大,形状不规则。边缘较模糊,与周围组织分界不清。病理所见:良性者多为淋巴细胞型(占53.3％),恶性者则多为上皮细胞型(占52.9％)。
Sixty-eight cases with thymoma (44 benign, 24 malignant) were analysed in clinical manifesta-tions, pathology and chest films. The results showed that thymoma was more cornmon in males with middle age (44. 1 ± 2. 6 years old)than in females. 16. 2% of patients were discovered in regu-lar physical examination without any symptoms. Myasthenia frequently occurred (77. 3%) in be-nign thymoma whereas chest pain in 20. 8% of malignant. The tumor often located in rniddle and upper anterior mediastmum umlatcrally. A large mass with irregular shape, ill-defined margin and inhomogeneous density could be found in malignant ;a small regular ,well-defined and homogeneous mass could be found in benign by X-ray examination. The body of malignant was 4 times larger than that of benign. 100% of benign tumors in Ⅰ and Ⅱ stages were completely removed,while only 8. 3% of malignant were completely removed and 79. 2% were partially operated due to their adhe-sion with peripheral tissues. In benign tumor,the integument was intact and the section appeared solid,homogeneous and fine. In malignant,the integument was incomplete,and the section appeared murky gray and cytosolid, focal hemorrhage or necrosis could be revealed. In pathological, 53. 4 % of the benign were lymphocytic and 52. 9% of mahgnant were reticuloepithelioid.
