Oral vegetable granuloma: ultrastructural and histological study
Journal of Oral Pathology
|July 1, 1986
Summary
This study investigates unusual oral lesions containing hyaline rings. Findings suggest these rings are vegetable remnants triggering a foreign-body inflammatory response with giant cells.
Area of Science:
- Oral Pathology
- Plant Biology
- Immunology
Background:
- Giant-cell granulomatous inflammatory oral lesions present diagnostic challenges.
- The nature of characteristic hyaline rings within these lesions remains debated, with theories including vascular degeneration or plant cell remnants.
Purpose of the Study:
- To elucidate the composition and origin of hyaline rings in oral giant-cell granulomatous inflammatory lesions.
- To determine the inflammatory response associated with these structures.
Main Methods:
- Light microscopy of ten oral lesions and various vegetables.
- Electron microscopy of the oral lesions.
- Comparative analysis of lesion material and vegetable cell wall structures.
Main Results:
- Light microscopy revealed hyaline rings within inflamed granulation tissue and multinuclear giant cells.
- Electron microscopy indicated hyaline rings are composed of material similar to vegetable cell walls, occasionally with a collagenous layer.
- Vegetable samples were examined for comparative analysis.
Conclusions:
- The hyaline rings in these oral lesions are consistent with vegetable remains.
- The observed inflammation is a foreign-body type response to these vegetable remnants.
