Multicystic mesothelioma of the peritoneum.

Multicystic mesothelioma is an uncommon lesion presenting as an abdominal mass. We report a 40-year-old woman presenting with recurrent intra-abdominal lump. She had undergone abdominal surgery thrice before. The lump at this presentation was partially excised surgically; histology and immunohistochemistry confirmed the diagnosis.
