Summary
Unusual appendicular pseudotumours, including diverticulosis, Crohn's disease, yersiniosis, and actinomycosis, can mimic appendicitis or tumours. Preoperative diagnosis is challenging, requiring consideration of these rare conditions in appendiceal disease.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Oncology
Background:
- Appendiceal masses present diagnostic challenges, necessitating differentiation between neoplastic, inflammatory, and infectious etiologies.
- Distinguishing benign from malignant appendiceal lesions preoperatively is crucial for appropriate management.
Observation:
- Five cases of unusual appendiceal pseudotumours were identified: appendicular diverticulosis (1), Crohn's disease (2), yersiniosis (1), and actinomycosis (1).
- Preoperative diagnoses included acute appendicitis (2) and suspected appendiceal tumour (3).
- All patients underwent surgery, with uneventful postoperative courses and specific medical treatments initiated for yersiniosis and actinomycosis.
Findings:
- Macroscopic and histological examination confirmed the pseudotumoural nature of the appendiceal masses.
- The study highlights the difficulty in preoperative differentiation of these rare appendiceal conditions.
Implications:
- These findings underscore the importance of considering rare differential diagnoses in appendiceal diseases presenting as masses.
- Enhanced preoperative diagnostic strategies may be needed to improve the accuracy of identifying these unusual appendiceal pathologies.
