[Colorectal polyps. Pathologico-anatomical and statistical studies on 3037 polyps].
Report on 3037 colorectal polyps from the Deutsche Klinik für Diagnostik Wiesbaden that were observed within about 6 years and submitted to microscopic examination. The polyps were classified according to the WHO nomenclature, 1976. Adenomas and metaplastic (hyperplastic) polyps were the most frequenty types. The terms 'carcinoma in situ,' 'focal carcinoma,' 'adenoma with severe cellular atypia,' and 'malignant polyp' are explained and discussed in view of possible false interpretations by the surgeon. It is stressed that only the term 'adenoma with severe cellular atypia' (WHO classification) should be retained. In 286 cases, primary multiplicity of polyps was observed. There were recurrent polyp(s) in 154 cases (7%). Most frequently the recurrent polyp(s) corresponded to the type that had been found during the first examination. Finally, some remarks are made concerning the techniques of biopsy and of pathological examination.
