Pseudomyxoma peritonei (PP) refers to accumulation of mucus in the peritoneal cavity, regardless of cause or pathogenesis. We have reviewed 8 cases of PP diagnosed in our institution over the past 5 years. Pertinent cytologic features include a mucinous background with mesothelial cells and histiocytes. Two cases contained rare clusters of neoplastic epithelial cells, with low‐grade nuclear features of malignancy. The origin and nature of the parent neoplasms were variable, with no reflection of the cytologic features of PP. Diagn Cytopathol 1996;14:10–13. © 1996 Wiley‐Liss, Inc.
