Pseudomyxoma Peritonei Arising From a Mucinous Ovarian Borderline Tumor Treated With Paclitaxel, Cisplatin, and Bevacizumab: A Case Report.

Pseudomyxoma peritonei (PMP) is a rare disease caused by primary mucinous neoplasms. Here, we describe a case where a large ovarian tumor was initially removed laparoscopically, followed by an appendectomy. The patient was diagnosed with PMP arising from an ovarian mucinous borderline tumor with a KRAS mutation. Treatment included bevacizumab-containing chemotherapy, resulting in complete remission.
