Appendiceal Adenocarcinoma in Pseudomyxoma Peritonei (PMP) - A Case Report

Pseudomyxoma peritonei (PMP), formerly known as gelatinous disease of the peritoneum, is a very rare pathology encompassing a spectrum of lesions characterized by the accumulation of a large amount of mucus accompanied by a variable number of cells in the peritoneal cavity and pelvis, sometimes associated with the presence of peritoneal cell implants. It is considered a tumor process, linked in the vast majority of cases to a mucinous appendiceal tumor. Pseudomyxomas can benefit from a therapeutic approach combining complete cytoreductive surgery and intraperitoneal chemotherapy, which significantly improves the prognosis. The rarity of this entity and the associated therapeutic strategy require specialized care structures and the support of clinical and pathological networks. We report the case of a 71-year-old woman with pseudomyxoma peritonei diagnosed by CT scan.
