Summary
Hyaline ring granuloma (HRG) is a rare oral lesion. This study analyzed 64 cases, finding it most common in the mandible, often after tooth extraction, and characterized by unique histopathologic features.
Area of Science:
- Oral pathology
- Surgical pathology
Background:
- Hyaline ring granuloma (HRG) is a distinct, though uncommon, oral lesion.
- Understanding its clinical and radiographic presentation is crucial for diagnosis.
Observation:
- Analysis of 64 literature cases and 2 new cases revealed HRG distribution: 42% central, 53% peripheral, and 5% in cyst walls.
- Radiographic findings included radiolucent areas in central HRG and alveolar ridge erosion in peripheral HRG.
- Most lesions occurred in edentulous mandibles (83%), often posterior to premolars, in patients with a history of trauma or tooth extraction.
Findings:
- The mean patient age was 43 years, with a 1.9:1 male-to-female ratio.
- While not typically painful, patients experienced discomfort like swelling and tenderness.
- Histopathologic diagnosis relies on identifying hyaline rings with giant cell inclusions.
Implications:
- Surgical excision or curettage is the standard treatment for HRG.
- Careful bone smoothing is recommended for peripheral HRG in edentulous areas to prevent recurrence.
- Complete removal is key, as recurrence, though uncommon, is linked to incomplete excision.
