Pseudomyxoma peritonei diagnosed by peritoneoscopy.

A case of pseudomyxoma peritonei diagnosed by peritoneoscopy is reported. The rarity of the tumour and the unfamiliarity of the surgeon with the vagaries of this condition often lead to a pessimistic diagnosis of advanced metastatic mucinous adenocarcinoma. It is suggested that peritoneoscopy may be of help both in the early diagnosis of pseudomyxoma peritonei, thus sparing patients from unnecessary investigations, and in their follow up, especially when the aggressive policy of multiple repeated resections of the recurrent or persistent lesions is to be adopted.
