This systematic review and meta-analysis evaluated the clinical and molecular characteristics of respiratory epithelial adenomatoid hamartoma (REAH) in 1127 patients across 39 studies. The analysis revealed that REAH is predominantly found in the olfactory cleft (66.7%) and often presents bilaterally (66.4%). Additionally, an enlarged olfactory cleft width of 10.58 mm was noted on CT scans.
Key findings
- REAH was identified in the olfactory cleft in 66.7% of cases.
- Bilateral presentation of REAH occurred in 66.4% of patients.
- The average olfactory cleft width in REAH patients was 10.58 mm.
Why it matters
Understanding the clinical and molecular features of REAH is crucial for accurate diagnosis, as it can mimic chronic rhinosinusitis with nasal polyposis. Clinicians should maintain a high index of suspicion for REAH in patients presenting with specific sinonasal symptoms.
