RT Journal Article SR Electronic T1 Ploidy studies in adenomatous polyps of the colon. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1261 OP 1264 DO 10.1136/jcp.38.11.1261 VO 38 IS 11 A1 F Whitehead A1 L R Jarvis A1 J M Skinner A1 R Whitehead YR 1985 UL http://jcp.bmj.com/content/38/11/1261.abstract AB The nuclei of colonic adenomatous polyps and some colonic carcinomas have a normal diploid profile. The remaining carcinomas are aneuploid, and this change most probably occurs after the dysplasia that determines invasiveness, because even adenomatous polyps with carcinoma in situ are diploid.
