Appendiceal mucoceles, rare appendix lesions causing obstruction, require careful diagnosis. Surgical approach depends on frozen section findings, ranging from appendectomy to colectomy.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Appendiceal mucoceles are rare, characterized by appendix enlargement due to mucoid accumulation.
  • This condition occurs in 0.1-0.4% of appendectomies, predominantly in females over 50.

Observation:

  • A case of benign mucocele presenting as a subocclusive syndrome is reported.
  • Diagnostic challenges exist in differentiating benign from malignant forms pre-operatively.
  • Imaging like ultrasound, CT, and colonoscopy can suggest diagnosis, but it's often incidental.

Findings:

  • Frozen section examination during surgery is crucial for determining the extent of resection.
  • Simple mucoceles without atypia may be treated with appendectomy.
  • Cystadenomas or cystadenocarcinomas necessitate more extensive surgery, like right colectomy.

Implications:

  • Accurate pre-operative diagnosis and intra-operative frozen section analysis guide appropriate surgical strategy.
  • Timely intervention prevents complications associated with appendiceal mucoceles.
  • Understanding pathogenesis and histology aids in managing these rare appendiceal lesions.
