Primary peritoneal cancer is an idiopathic malignancy originating from the peritoneal layers of the abdominal cavity.The condition is attributed to the [t(11;22)(p13;q12)] translocation.[6]

Secondary peritoneal carcinomatosis typically arises from invading malignant cells from tumors affecting various organs, including the stomach, colon, pancreas, gallbladder, appendix, breast, uterus, ovary, and lungs.Leiomyosarcoma, conversely, is a secondary tumor often associated with Li-Fraumeni syndrome, which also predisposes individuals to retinoblastoma.This condition primarily affects older men (60+).[5]

Disseminated peritoneal leiomyomatosis is linked to a heightened estrogenic state observed in postmenopausal women.Desmoplastic small round cell tumor (DSRCT) predominantly affects adolescents, with a median age of 19, and is notably more prevalent among White individuals (85%).While rare, there are sporadic reports of EOPPC occurring in men.

Primary peritoneal cancer is an idiopathic malignancy originating from the peritoneal layers of the abdominal cavity. The subtype EOPPC shares similarities with serous ovarian carcinoma and predominantly affects women (mean age of 56-62). While rare, there are sporadic reports of EOPPC occurring in men. Germline mutations in the BRCA1 gene have been identified in approximately 17.6% of EOPPC cases.[1] Therefore, in patients with a history of familial breast cancer, the possibility of serous peritoneal cancer should be considered. Malignant peritoneal mesothelioma (MPM), on the other hand, is an aggressive tumor associated with asbestos exposure in 33% to 50% of cases. This condition primarily affects older men (60+).[5]

Secondary peritoneal carcinomatosis typically arises from invading malignant cells from tumors affecting various organs, including the stomach, colon, pancreas, gallbladder, appendix, breast, uterus, ovary, and lungs. Peritoneal involvement, specifically in appendiceal cancer, is termed pseudomyxoma peritonei; often, this is effectively managed and can result in a lifetime free from relapse. However, metastasis from ovarian, gastric, and colorectal malignancies is associated with an increased risk of recurrence and mortality. These 3 types of cancer are also the most common causes of metastatic spread to the peritoneum.
