Primary peritoneal cancer

Primary peritoneal carcinoma (PPC) refers to a malignant tumor that originates in the peritoneal mesothelium and grows multifocally and is rarely seen clinically. The histological characteristics are consistent with the same type of tumors with the same degree of differentiation in the ovaries, with the ovaries normal or only superficially involved. The disease was first reported by Swerdlow in 1959 as "pelvic peritoneal mesothelioma resembles ovarian papillary cystadenocarcinoma", but it has not attracted much attention. In 1977 Kannerstein reported 15 cases, first named "primary peritoneal papillary serous carcinoma", which clearly distinguished this disease from peritoneal malignant mesothelioma.
