We report here two unusual cases of a rare tumour “pseudomyxoma peritonei”. 1. Case one: A 55 -year- old female patient, with history of carcinoma of left breast presented with ascites which was proved to be due to pseudomyxoma peritonei rather than to metastases from breast cancer. 2. Case two: An 18 –year- old male patient presented with huge abdominal distention in whom a diagnosis of pseudomyxoma peritonei was confirmed; an unusual age and sex for this rare tumour.
