Laparoscopic peritoneal mucinous cystadenoma debulking: A case report

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pathology

Background:

• Peritoneal mucinous cystadenoma is a rare neoplasm with nonspecific clinical, serological, and imaging findings, leading to frequent misdiagnosis.
• Early and accurate diagnosis is challenging, necessitating high clinical vigilance.

Purpose of the Study:

• To report a case of peritoneal mucinous cystadenoma treated with laparoscopic stripping.
• To enhance understanding of the diagnostic and therapeutic challenges associated with this rare condition.

Main Methods:

• A 34-year-old female presented with epigastric pain, initially suspected to have cholelithiasis and hepatic cysts.
• Imaging revealed a low-density mass between the liver and kidney; preoperative tumor markers were normal.
• Laparoscopic surgery was performed, with the procedure converted to cyst removal and cholecystectomy upon intraoperative identification of the peritoneal origin.

Main Results:

• Postoperative pathological examination confirmed peritoneal mucinous cystadenoma.
• The patient experienced an uneventful recovery and was discharged on postoperative day four.

Conclusions:

• Clinical diagnosis of peritoneal mucinous cystadenoma is challenging, often requiring postoperative pathological confirmation.
• Surgical intervention is the primary treatment, emphasizing careful cyst handling to prevent rupture.
• Consideration of this diagnosis is crucial when cystic lesions are identified within the abdominal cavity.
