胃肠道间质瘤19例临床病理特征分析
Spontaneous hematoma in abdominal cavity misdiagnosed as interstitialoma: report of one case
腹腔内自发性血肿误诊为间质瘤1例
Results The GIST and parenteral interstitialoma in the 39 cases were mainly composed of spindle cells and epithelioid cells in which CD117 was positive in 38 cases and CD34 was positive in 32 cases.

胃肠道间质瘤（gastrointestinalstromaltumors，GISTs）是消化道最常见的原发性间叶性肿瘤，大多数发生在胃和小肠。
Conclusion GIST and parenteral interstitialoma are the most common stromal tumors of gastrointestinal and parenteral tract with multiple differentiated potentiality and similar morphology. Positive expression of CD117 and CD34 is significant to diagnose GIST and parenteral interstitialoma.
结论胃肠间质瘤具有多向分化性，HE形态类似，CD117、CD34免疫标记阳性对诊断有意义。
