# Pseudomyxoma Peritonei: An Incidental Diagnosis With Atypical Intraoperative Findings Discovered During a Laparoscopic Cholecystectomy

## TL;DR

A rare case of pseudomyxoma peritonei was discovered during a routine gallbladder surgery in a man with no obvious symptoms.

## Contribution

This case highlights an atypical, mild presentation of PMP with minimal symptoms and unusual intraoperative findings.

## Key findings

- PMP was diagnosed incidentally during a laparoscopic cholecystectomy in a 43-year-old male.
- The case showed atypical features, including sparse mucinous deposits and numerous adhesions.
- The case suggests that PMP can present in an indolent and insidious manner.

## Abstract

Although pseudomyxoma peritonei (PMP) classically presents with profuse mucinous ascites within the peritoneal cavity, the physical manifestations of this disease exist on a spectrum, with the possibility of milder forms that lack typical findings. The authors report an indolent case of PMP diagnosed incidentally during workup and treatment for chronic cholecystitis in a 43-year-old male. This presentation of PMP was atypical due to a lack of discernible symptoms as well as uncharacteristic intraoperative findings consisting of numerous omental and pelvic adhesions with only sparse mucinous deposits. This case contributes to the growing understanding of PMP by exploring an uncharacteristic presentation of the disease with the hope that it may assist clinicians in diagnosing those cases of PMP that are more indolent and insidious in nature.
