| Popis: |
This chapter covers non-tumorous lesions and excludes the neoplasms and the tumor-like lesions covered previously (Gourtsoyiannis and Nolan 1997). Any discussion of the non-neoplastic conditions of the small intestine requires a review of the normal histology since medical conditions involving the mucosa often show only slight variations from normal. Understanding the normal histology is the most important step in understanding the abnormal histology. It is important that clinicians and pathologists embrace the concept that diagnostic specificity often requires clinical, endoscopic, and radiologic information since a specific histologic reaction may be due to any of several injurious etiologic agents. Surgical intervention is rarely required for most non-neoplastic conditions of the small bowel; therefore, the diagnosis is generally made from mucosal biopsies. In view of this, we shall attempt to correlate the histopathology largely from mucosal biopsies with endoscopic features since endoscopy is the equivalent of gross pathology. |
