# Fertility-sparing surgery in primary peritoneal serous borderline tumor: a case report

## TL;DR

A rare tumor in young women can be treated with fertility-preserving surgery after confirming it is not ovarian cancer.

## Contribution

This case report demonstrates the feasibility of fertility-sparing surgery for primary peritoneal serous borderline tumor.

## Key findings

- Fertility-sparing surgery was successfully performed in a reproductive-aged woman with PPSBT.
- Comprehensive surgical staging and multidisciplinary evaluation are essential for optimal outcomes.
- FSS is a viable option after excluding ovarian malignancy in PPSBT patients.

## Abstract

Primary peritoneal serous borderline tumor (PPSBT) is a rare, low-malignant-potential neoplasm arising from the peritoneum, diagnosed only after excluding ovarian involvement. While typically discovered incidentally during surgery, it often presents with infertility or abdominal pain in young women. Due to its favorable prognosis and the desire to preserve fertility, fertility-sparing surgery (FSS) is a critical consideration. We report a case of PPSBT in a reproductive-aged woman who underwent three FSS procedures, demonstrating the feasibility of this approach. Our findings support FSS as a viable option for PPSBT patients after thorough exclusion of ovarian malignancy. This case underscores the importance of comprehensive surgical staging and multidisciplinary evaluation to optimize oncological and reproductive outcomes. Further research is needed to standardize management strategies for this rare condition.
