Summary

A rare case of appendiceal inflammatory pseudotumor, a benign lesion, was diagnosed in a male patient presenting with abdominal pain. This finding highlights the importance of considering unusual diagnoses in appendiceal pathology.

Area of Science:

  • Gastroenterology
  • Pathology
  • Surgical Oncology

Background:

  • Appendiceal tumors are rare, with most being malignant.
  • Inflammatory pseudotumors are typically found in the stomach and intestines.

Observation:

  • A 41-year-old male presented with abdominal pain, initially suspected as acute appendicitis.
  • Ultrasonography revealed a tumorous lesion of the appendix.
  • Laparotomy identified mass lesions in the mid and distal appendix.

Findings:

  • Histological examination confirmed an inflammatory pseudotumor.
  • The lesion showed significant eosinophilic cell and fibroblastic infiltration.
  • The growth pattern was predominantly intramural rather than intraluminal.

Implications:

  • This case represents an extremely rare occurrence of an inflammatory pseudotumor in the appendix.
  • Accurate diagnosis is crucial, distinguishing it from malignant appendiceal neoplasms.
  • The term 'pseudotumor' is appropriate given the lesion's characteristics and location.
