Pseudomyxoma peritonei presenting as sub-acute large bowel obstruction.

Area of Science:

• Gastroenterology
• Oncology
• Surgical Pathology

Background:

• Pseudomyxoma peritonei (PMP) is a rare clinical entity characterized by the mucinous ascites and gelatinous implants on peritoneal surfaces.
• It is typically associated with mucinous tumors of the appendix, but can also arise from other gastrointestinal or ovarian sources.
• PMP presents a diagnostic and therapeutic challenge due to its rarity and propensity for recurrence.

Observation:

• A 30-year-old male presented with symptoms suggestive of sub-acute large bowel obstruction.
• Diagnostic workup revealed extensive mucinous deposits within the peritoneal cavity.
• The patient underwent surgical intervention for the obstruction and tumor debulking.

Findings:

• Histopathological examination confirmed pseudomyxoma peritonei, originating from a mucinous neoplasm.
• The tumor's extensive peritoneal spread led to the observed bowel obstruction.
• Literature review indicates varied presentations and management strategies for PMP.

Implications:

• This case highlights the importance of considering rare diagnoses like PMP in patients with bowel obstruction.
• Early recognition and appropriate surgical management are crucial for improving patient outcomes.
• Further research into the pathogenesis and optimal treatment of PMP is warranted.
