"The Jelly Belly": Diagnostic Dilemmas and Current Concepts.

Area of Science:

• Oncology
• Gastroenterology
• Pathology

Background:

• Pseudomyxoma peritonei (PMP) is a rare condition characterized by mucinous ascites and peritoneal implants.
• While historically debated, the appendix is now favored as the primary origin of PMP over the ovaries.
• Classification challenges and limited understanding complicate PMP diagnosis and management.

Purpose of the Study:

• To present three cases of Pseudomyxoma peritonei in postmenopausal women.
• To discuss the clinical presentation, pathological staging, and treatment of PMP.
• To emphasize current concepts in PMP origin and management.

Main Methods:

• Case series reporting on three postmenopausal women with PMP.
• Clinical presentation and pathological staging of peritoneal tumor deposits were analyzed.
• Treatment administered and patient outcomes were documented.

Main Results:

• Two patients experienced uneventful recovery after treatment for PMP.
• One patient developed a recurrence of adenocarcinoma.
• The study highlights variability in PMP patient outcomes.

Conclusions:

• PMP presents diagnostic and management challenges due to its rarity and evolving classification.
• Complete tumor removal and accurate classification are crucial for preventing mortality.
• Understanding the appendiceal origin of PMP is key for effective treatment strategies.
