Summary
Splenic involvement in Wegener's granulomatosis is uncommon but may cause significant illness. This review highlights its varied pathology and underdiagnosis during life.
Area of Science:
- Pathology
- Rheumatology
- Internal Medicine
Background:
- Wegener's granulomatosis is a rare autoimmune vasculitis.
- Splenic involvement is not well-characterized in the literature.
Observation:
- A retrospective review identified five patients with Wegener's granulomatosis and splenic involvement over 10 years.
- The study was conducted at a large teaching hospital and outpatient clinics.
Findings:
- One patient showed necrotizing granulomatous inflammation and vasculitis in the spleen antemortem.
- Autopsy revealed infarction, necrosis, microcalcification, and vascular thrombosis in two cases, with no vasculitis.
- Two other cases had nonspecific changes like hyalinization, congestion, and hemosiderin deposition.
Implications:
- Splenic involvement in Wegener's granulomatosis is likely more frequent than clinically recognized.
- It can lead to significant patient morbidity.
- Early diagnosis and management are crucial.
