Tumor-like diseases of the peritoneum: description of a clinical case of treatment of peritoneal inclusion cyst

This paper presents a clinical case of a rare peritoneal lesion. It was classified previously as a multicystic peritoneal mesothelioma, but is now considered a tumor-like disease. Despite the morphological signs of a benign formation, the disease course was unusually aggressive, which was expressed in early and repeated relapses.
