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

## TL;DR

A rare case of pseudomyxoma peritonei from an ovarian tumor was successfully treated with chemotherapy and bevacizumab.

## Contribution

This case report highlights the successful treatment of PMP with a KRAS mutation using bevacizumab-containing chemotherapy.

## Key findings

- PMP arose from an ovarian mucinous borderline tumor with a KRAS mutation.
- Treatment with bevacizumab-containing chemotherapy led to complete remission.
- Laparoscopic surgery followed by appendectomy was part of the treatment approach.

## Abstract

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.
