Abstract：
Gastrointestinal tactile corpuscle-like bodies are a rare, incidental, entirely benign finding. It is mainly reported in the colorectum and esophagus/gastro-esophageal junction. Rare cases have been documented in the stomach. Here, we present two cases of gastric and colonic tactile corpuscle-like bodies of a 38-year-old female and a 55-year-old male, respectively. Endoscopically, the colonic lesion was resected as an adenomatous polyp, while the gastric biopsies were taken to rule out Helicobacter pylori (H. pylori) gastritis. Microscopically, both specimens revealed the same histopathologic aspects of eosinophilic fibrillary material with round to oval cells and peripherally placed nuclei. Immunohistochemically, these lesions were positive for anti-S100, confirming the diagnosis of tactile corpuscle-like bodies. A thorough literature review is provided.
摘要：
胃肠触觉小体是一种罕见的，附带的,完全良性的发现。主要报道在结肠直肠和食管/胃食管交界处。罕见的病例已在胃中记录。这里,我们介绍了两例38岁女性和55岁男性的胃和结肠触觉小体样身体，分别。内窥镜检查,结肠病变被切除为腺瘤性息肉，虽然进行了胃活检以排除幽门螺杆菌(H.幽门螺杆菌)胃炎。微观上,两个标本都显示了相同的组织病理学方面的嗜酸性原纤维物质，具有圆形到卵圆细胞和周围放置的细胞核。免疫组织化学，这些病变的抗S100抗体呈阳性,证实了触觉小体的诊断.提供了全面的文献综述。
