Diagnostic Challenges and Multimodal Treatment in Primary Peritoneal Cancer: a Case Report

Peritoneal cancer (PPC), a rare and aggressive malignancy, can develop from the peritoneal lining or as a secondary peritoneal cancer caused by metastases from neighbouring organs such as the ovaries, gastrointestinal tract, or breast. Early identification is still difficult due to its ambiguous signs, ranging from bloating, distension, and stomach pain. Due to their comparable histological and clinical characteristics, PPC and ovarian cancer are frequently misdiagnosed. Advanced imaging, histological investigation, and immunohistochemical markers are essential for accurate diagnosis. In order to control any remaining disease and enhance results, treatment usually encompasses an assortment of therapeutic approaches, such as hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgical procedure (CRS). We present a 69-year-old woman who got diagnosed with PPC after first being suspected of having ovarian cancer. The current instance emphasizes how crucial a thorough diagnostic process is to differentiating PPC from related cancers.
