Summary
Operating microscope (OM) evaluation revealed detailed microscopic features of localized juvenile spongiotic gingival hyperplasia (LJSGH). OM aids in identifying subtle gingival lesion characteristics not seen in conventional exams.
Area of Science:
- Oral pathology
- Dermatology
- Microscopy
Background:
- Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a rare gingival overgrowth.
- Clinical diagnosis can be challenging due to subtle presentations.
Purpose of the Study:
- To describe the clinical microscopic features of LJSGH using an operating microscope (OM).
- To assess OM as a non-invasive diagnostic tool for oral mucosal lesions.
Main Methods:
- An 18-year-old female with LJSGH underwent conventional examination and OM evaluation.
- An incisional biopsy was performed for histopathological analysis.
Main Results:
- OM visualized gingival surface irregularities, vascular spots, exudation, and friable tissue.
- Histopathology confirmed LJSGH with acanthosis, spongiosis, and inflammatory infiltrate.
- OM identified features like vascularity and exudation not apparent in conventional exams.
Conclusions:
- OM is a valuable adjunct for evaluating and documenting gingival lesions.
- OM provides detailed visualization of LJSGH features.
- This technique enhances the understanding of oral mucosal lesions.
