Microscopic foreign objects are sometimes found in gastrointestinal (GI) tract specimens. Some signify important diagnostic findings, such as parasitic or bacterial organisms and some medication resins. Partially digested fruits and vegetables can also be present, and some have been described in the literature as potential mimickers of clinically important findings. While animal protein appears as skeletal muscle on histologic examination, fruits and vegetables can show a wide variation under the microscope. To our knowledge, a thorough histologic examination of commonly eaten fruits and vegetables has not been published in the pathology literature. Herein, we present key morphologic features of fruits and vegetables that might be found in GI specimens, emphasizing potential mimics of significant pathologic findings.

胃肠道（GI）道标本中有时会发现微小的异物。有些代表重要的诊断结果，例如寄生或细菌生物以及某些药物树脂。也可能存在部分消化的水果和蔬菜，并且在文献中已将其中一些描述为对临床重要发现的潜在模仿。在组织学检查中，动物蛋白以骨骼肌的形式出现，而水果和蔬菜在显微镜下可以显示出很大的差异。据我们所知，在病理学文献中尚未对常见食用水果和蔬菜进行彻底的组织学检查。在这里，我们介绍了可能在胃肠道标本中发现的水果和蔬菜的关键形态特征，着重指出了可能具有重大病理发现的模拟物。
