Six cases of pseudomyxoma peritonei were reviewed cytologically and histologically. Abundant mucus and epithelial cells with invariable size and figure were commonly observed as the ascitic picture of the present disease.Intestinal epithelium-like fragments were also often intermingled, associated with signet ring cells. In addition, atypical cells, though small in number, were found in all 6 cases.The cells were characterized by enlargement in size, prominent nuc leoli and coarse chromatin. And in these cases, in which the cells were more atypical in morphology and larger in number, survival times were shorter.
