With the advent of endoscopic techniques, the gastrointestinal tract has now become more accessable to clinical investigators. Polyps are amongst the commonest abnormalities biopsed and submitted for histological assessment. The biological behavior of a polyp realtes entirely to its pathological nature and accurate histological diagnosis is therefore vital. While so many textbooks and atlases include polyps in sections on gastrointestinal tumours, none have been so comprehensively devoted to the polyp as Gastrointestinal Polyps. The layout of the book has been desigened sequentially to describe the commoner synonyms when appropriate, the prevalence, the endoscopic/macroscopic appearences and microscopic features followed bya section on the biological behaviour and associated conditions. There is a section on treatment, if applicable, and an invaluable list of key references. Profusely illustrated in full colour throughout, it is designed to be the complete companion: a bench book not only for the practising histopathologist who regularly examines oesophageal, gastric, duodenal and intestinal polyps as part of his or her daily work but also for the endoscopist who regularly biopsies them.
