Description
Abstract
We report a case of benign multicystic
mesothelial proliferation (the so-called multicystic
peritoneal mesothelioma) arising multifocally in the
abdomen of a 46-year-old white man. His anamnesis
showed an 8-year history of intermittent pain in
the right lower abdominal quadrant. Mucin stains,
immunohistochemistry, and electron microscopy
confirmed the mesothelial origin of the lesion. Review
of the available literature allowed us to find another 85
reported cases of benign multicystic mesothelial
proliferations of the peritoneum. Out of these cases,
eighteen only occurred in men, the majority being
reported in middle-aged women mostly with
complaints of abdominal pain. Electron microscopy
or immunohistochemistry are needed to make a
differential diagnosis towards other multicystic
lesions, such as peritoneal cystic lymphangioma.
Although multicystic mesothelial proliferations
of the peritoneum have often been regarded as
benign neoplasms, the true nature - neoplastic or
hyperplastic - of these lesions still remains greatly
elusive. Therefore, we believe that the unbinding term
benign multicystic mesothelial proliferation (first
used with regard to the unique hitherto reported case
arisen in the pleural cavity) should be considered at
present more appropriate to indicate even these
peritoneal lesions.
