[Well-differentiated papillary mesothelioma of the peritoneum: an attenuated malignant tumor. Review of the literature apropos of a case]

The authors present a new case of a well-differentiated papillary mesothelioma of the peritoneum. This is an uncommon tumor which have a slow evolution like a low malignant potential tumor. But, because of its tendency to recurrence, the designation of Well-Differentiated Tumor is better. The diagnosis with others peritoneal tumors is sometimes difficult, especially with the Peritoneal Serous Tumors. Tumor recurrence must be treated by curative surgery. Adjuvant therapy is discussed for the diffuse form.
