{Reference Type}: Case Reports {Title}: Pseudomyxoma Peritonei Misdiagnosed as Liver Cirrhosis: A Case Report and Literature Review. {Author}: Alkhalil N;Al Omary A; {Journal}: Cureus {Volume}: 16 {Issue}: 4 {Year}: 2024 Apr 暂无{DOI}: 10.7759/cureus.57857 {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.
