mucinous cystadenoma a multilocular, usually benign, tumor produced by ovarian epithelial cells and having mucin-filled cavities.
papillary cystadenoma any tumor producing patterns that are both papillary and cystic; called also papilloadenocystoma.

mucinous cystadenoma

A benign proliferation of cuboidal epithelium often within a cystic space, which may be seen in the ovary, pancreas or, far less commonly, the liver. The stroma is described as ovary-like and stains with mucicarmine and inhibin.

Appendix
A benign epithelial neoplasm that may be diffuse or focal (with small polyps), often associated with dilation of the appendix, mucin dissection into the wall and release of mucin into the peritoneum (”pseudomyxoma peritonei”).

Pathology
Dilation of appendix with a single layer of neoplastic epithelium with low-grade dysplasia, undulating morphology, villous or tubulovillous architecture, or serrated appearance.
