Primary Peritoneal Carcinomatosis: A Case Report
Abstract
Primary peritoneal adenocarcinoma (PPC) is an uncommon malignancy that arises from the peritoneal lining and shares striking clinical, histopathological, and immunophenotypic similarities with epithelial ovarian carcinoma (EOC). Because both entities derive from Müllerian epithelium, distinguishing PPC from metastatic ovarian or gastrointestinal carcinoma poses a significant diagnostic challenge, particularly in the absence of detectable ovarian masses. Recognizing this rare entity is clinically relevant, as accurate classification influences prognosis, genetic counseling, and management strategies.
