Samples of gastric leiomyosarcomas from two male patients (69 years and 57 years of age) were studied by electron microscopy. The tumour cells contained abundant 50--90 A thick microfilaments and microtubules. Another cell type, regarded as immature leiomyosarcoma cell, contained numerous profiles of granular endoplasmic reticulum, free ribosomes and a well developed Golgi apparatus. There were intercellular junctions of zonula adherens-type between adjacent tumour cells. It was concluded that electron microscopy offers a valuable aid in the diagnosis of gastric neoplasms of smooth muscle origin.
对两名男性患者（分别为69岁和57岁）的胃平滑肌肉瘤样本进行了电子显微镜研究。肿瘤细胞含有丰富的50 - 90埃厚的微丝和微管。另一种细胞类型，被认为是未成熟的平滑肌肉瘤细胞，含有大量的粗面内质网、游离核糖体和发育良好的高尔基体。相邻肿瘤细胞之间存在粘着小带型的细胞间连接。结论是电子显微镜在诊断平滑肌源性胃肿瘤方面提供了有价值的帮助。
