The authors report a case of Pseudomyxoma Peritonei (PP) which was referred to their attention. PP is a rare pathology which is manifested by an autonomous growth of amorphous mucous material in the peritoneal cavity and serosa. PP may be caused by the perforation of a "mucinous cystoadenoma" with secretion of cellular material capable of implanting itself and spreading throughout the peritoneal cavity, or the presence of a mucocele of the appendix, or lastly the possibility of the intrabdominal transformation of the peritoneal mesothelium into mucin-secreting tissue
