From the introduction 'The purpose of the atlas is to provide surgical pathologists with ready expert material most helpful in their daily practice.
The lesions described relate principally to medical non-neoplastic conditions. Many of these lesions represent complex entities and when appropriate we have included contributions from internists radiologists and surgeons. This has led to some increase in the size of the monographs but the emphasis remains on diagnosis by the surgical pathologist.
Previously the Fascicles have been available on CD-ROM format as well as in print. In order to provide the widest possible advantages of both modailities we have formatted the print fascicle on the World Wide Web. Use of the internet allows cross-indexing within the fascicles as well as linkage to PubMed '
From the Preface:
'This fascicle is devoted to benign gastrointestinal diseases and provides an in-depth discussion of many lesions, both common and uncommon. This volume is for the most part organized by category of disease rather than by anatomic site. This approach allows us to cover each entity comprehensively and avoids redundant descriptions of lesions that occur in multiple regions of the gastrointestinal tract. Each disease entity is discussed from the point of view of its demographics, pathophysiology, clinical features, gross and microscopic pathology and treatment..'
