Malignant Peritoneal Mesothelioma Presenting as Ascites of Unknown Origin

摘要

Malignant mesothelioma is a rare but highly aggressive and fatal tumour arising from the mesothelial cells, which is associated with an involvement of the peritoneum in 30% of cases. We report a 48-year-old man with malignant peritoneal mesothelioma who presented with ascites of unknown origin, and discussed the clinical presentation, investigation and management, as well as the diagnostic difficulties in managing this unusual and unfortunate case.
