The presence of the so-called "skeinoid fibers" in stromal tumours of the gastrointestinal tract is a rare event. The exact origin of this puzzling group of neoplasms still remains controversial. Despite all, the recognition of this histologic feature in routine practice is important for its presence seems to carry histogenetic implications. The authors report the histopathologic findings of two of such cases both occurring in the jejunum of a male aged 48 and a woman, 64. Their positivity with CD 34 antigen is enhanced, for this peculiar immunophenotype help to distinguish them from other stromal tumors in the small bowel. Additionally, the literature is reviewed and commented.
胃肠道间质瘤中所谓的“束状纤维”的存在是一种罕见现象。这类令人费解的肿瘤的确切起源仍存在争议。尽管如此，在常规实践中识别这一组织学特征很重要，因为它的存在似乎具有组织发生学意义。作者报告了两例这样的病例的组织病理学发现，这两例均发生在一名48岁男性和一名64岁女性的空肠中。它们对CD 34抗原的阳性反应增强，因为这种特殊的免疫表型有助于将它们与小肠中的其他间质瘤区分开来。此外，还对相关文献进行了综述和评论。
