RT Journal Article SR Electronic T1 Gross pathology of the placenta: weight, shape, size, colour JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1285 OP 1295 DO 10.1136/jcp.2008.055269 VO 61 IS 12 A1 Kaplan, C G YR 2008 UL http://jcp.bmj.com/content/61/12/1285.abstract AB The gross examination is critical to making accurate diagnoses on placental specimens. An orderly evaluation of the cord, membranes and villous tissue allows maximal opportunity to recognise abnormalities. Many lesions have a pathognomonic gross appearance, while other processes are best seen on histology. Quantitation of the volume of placental tissue involved in an abnormal process is necessary to distinguish normal variation from significant pathology. Histological sections must include cord, membranes and central villous tissue.
