Abstract

This article focuses on the diverse benign tumors and tumor-like conditions affecting the small intestine and ampulla of Vater, which can mimic malignant neoplasms and pose diagnostic challenges for pathologists. It categorizes these lesions into six groups: Brunner gland lesions, various polyps (adenomatous, hyperplastic, hamartomatous, inflammatory), mesenchymal proliferations, fibrosis-associated diseases, lymphatic vessel disorders, and other rare conditions such as enteritis cystica profunda and pneumatosis cystoides intestinalis. The review emphasizes the histopathological features and differential diagnoses of each entity, providing a concise reference to aid routine diagnostic practice. It draws extensively on content from the PathologyOutlines website and includes a summarizing table of key diagnostic hallmarks and differential diagnoses for each condition.
