Pseudomyxoma peritonei peritonitis

Area of Science:

• Gastroenterology
• Oncology
• Surgical Pathology

Background:

• Pseudomyxoma peritonei (PMP) is a rare neoplastic condition characterized by mucinous ascites.
• It typically originates from mucin-producing appendiceal tumors, necessitating prompt recognition and specialist care due to malignancy potential.

Purpose of the Study:

• To present a case of Pseudomyxoma peritonei (PMP) arising from a ruptured appendix.
• To highlight the importance of prompt diagnosis and surgical intervention in managing PMP.

Main Methods:

• A diagnostic laparoscopy was performed on a male patient presenting with acute abdominal pain.
• Extensive intra-abdominal mucin was identified and removed.
• A laparoscopic appendectomy was conducted.

Main Results:

• Histopathology confirmed Pseudomyxoma peritonei (PMP) originating from a ruptured appendix.
• The patient's presentation included right iliac fossa peritonism and elevated inflammatory markers.

Conclusions:

• Pseudomyxoma peritonei (PMP) can present acutely and mimic other abdominal pathologies.
• Laparoscopic appendectomy and mucin washout are key management steps for PMP originating from the appendix.
