Seven patients with tumor-like granulomatous lesions of the peritoneal cavity were cured, except one, by correct surgical intervention removing the inflammatory hyperplastic tissues and restoring the permeability of the alimentary tract. The exact diagnosis was suggested by the existence in the personal history of the patients of one or several interventions on the peritoneal cavity (6 of 7), and was confirmed by intraoperative, sometimes repeated, microscopic examination, rendering evident a fibrogenous giant cell granulomatous process; the presence of foreign bodies, especially suture threads or crystals (the latter characterized in polarized light) is very helpful for the diagnosis of these tumor-like inflammations.

Ovarian cancer (OC) ranks as the fifth leading cause of cancer-related deaths in the United States, posing a significant threat to female health. Late-stage diagnoses, driven by elusive symptoms often masquerading as gastrointestinal issues, contribute to a concerning 70% of cases being identified in advanced stages. While early-stage OC brags a 90% cure rate, progression involving pelvic organs or extending beyond the peritoneal cavity drastically diminishes it.

In this editorial we examine the article by Wu published in the . Surgical resection for peritoneal metastases from colorectal cancer (CRC) has been gradually accepted in the medical oncology community. A randomized trial (PRODIGE 7) on cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) failed to prove any benefit of oxaliplatin in the overall survival of patients with peritoneal metastases from colorectal origin.

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear.

Aims: Endometriosis development is associated with peritoneal immune microenvironment abnormality; however, the specific mechanism is uncertain. We aimed to investigate the effects and underlying mechanisms of uterine cavity-derived exosomes on macrophage polarization and endometriosis progression.
Materials And Methods: Uterine cavity-derived exosomes, miR-210-3p inhibitor or siATP5D were used to treat macrophages.
