Ascites, Gelatinous

A condition characterized by poorly-circumscribed gelatinous masses filled with malignant Mucin-secreting Cells. Forty-five percent of pseudomyxomas arise from the Ovary, usually in a Mucinous Cystadenocarcinoma (Cystadenocarcinoma, Mucinous), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from Mucinous spillage into the Peritoneum by a benign Mucocele of the Appendix. (Segen, Dictionary of Modern Medicine, 1992)
