title: Polyps: the pathologist's perspective.
abstract: Adenomas of the colon and rectum are perhaps the most commonly encountered of human benign epithelial neoplasms. Evidence of their relationship to the development of colorectal carcinoma has mounted over the years. They represent a phase present for significant duration in many fated to develop colon cancer. Because of this, and because of the technical advances in endoscopy, a great deal of effort has been expended on identifying and removing these lesions. Subsequent care of the patient is heavily dependent on the pathologic analysis of these lesions. they must be properly classified; the presence of cancer must be carefully sought. If present, the character and location of the cancer arising in the polyp must be carefully described. Communication between clinician and pathologist if of paramount importance. Attention must be paid to the precise meaning of such terms as dysplasia, carcinoma, and invasion. The pathologist's report needs to detail parameters important in determining prognosis and further therapy.
