cystadenoma

 [sis-tad″ĕ-no´mah]
cystoma blended with adenoma.
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.
serous cystadenoma a cystic tumor of the ovary containing thin, clear yellow serum and some solid tissue.

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.

11) We felt that because appendiceal tumors that are confined to the appendix (ergo, mucinous cystadenoma or villous adenoma) are indistinguishable from those that have spread to the peritoneum, a single term should be used to encompass low-grade appendiceal mucinous tumors, regardless of their stage.
Mucoceles can be divided into 3 categories: (1) retention mucocele with normal/hyperplastic appendiceal mucosa; (2) mucinous cystadenoma with neoplastic epithelium similar to that seen in villous adenomas and adenomatous polyps; and (3) mucinous cystadenocarcinoma with neoplastic epithelium similar to that seen in adenocarcinoma of the colon.
