# Pseudomyxoma Peritonei Misdiagnosed as Liver Cirrhosis: A Case Report and Literature Review

## TL;DR

A rare abdominal cancer was misdiagnosed as liver cirrhosis, highlighting the need for accurate diagnosis to ensure proper treatment.

## Contribution

This case report highlights the diagnostic challenges of pseudomyxoma peritonei and emphasizes the importance of early detection.

## Key findings

- PMP was initially misdiagnosed as liver cirrhosis due to similar symptoms.
- Mucinous ascites identified through paracentesis led to the correct diagnosis of PMP.
- The case underscores the need for specialized centers for effective treatment.

## Abstract

Pseudomyxoma peritonei (PMP) is a rare intra-abdominal malignancy characterized by diffuse dissemination of mucinous tumor cells, leading to mucinous ascites. Accurate diagnosis is crucial for appropriate management. This report presents a case of a 55-year-old Lebanese male farmer initially misdiagnosed with liver cirrhosis who presented with progressive abdominal distension refractory to diuretics and dietary modifications. Paracentesis revealed a mucinous exudate, with subsequent clinical and histopathological examination confirming PMP. The patient was referred for further evaluation at a specialized center equipped for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). This case highlights the diagnostic challenges of PMP due to its non-specific presentation, emphasizing the importance of prompt and accurate diagnosis to facilitate optimal therapeutic intervention.
