Unusual gingival epithelial proliferation: primary pseudoepitheliomatous hyperplasia
Oral Surgery, Oral Medicine, and Oral Pathology
|May 1, 1979
Summary
A rare gingival tumor in a child, mimicking carcinoma, was successfully removed. This pseudoepitheliomatous hyperplasia, possibly from a dental lamina cyst, showed no recurrence after two years.
Area of Science:
- Oral pathology
- Pediatric dentistry
- Surgical oncology
Background:
- Pseudoepitheliomatous hyperplasia (PEH) can mimic squamous cell carcinoma.
- Gingival lesions in children require careful differential diagnosis.
- Dental lamina cysts are developmental remnants with potential for atypical proliferation.
Observation:
- A 9-year-old boy presented with a primary gingival lesion exhibiting histologic features suggestive of carcinoma.
- The lesion was surgically excised.
- Post-operative follow-up revealed no recurrence after 2 years.
Findings:
- The gingival lesion was diagnosed as pseudoepitheliomatous hyperplasia.
- Histologic features were atypical, raising initial concern for malignancy.
- The proposed histogenesis involves atypical proliferation of an aborted gingival cyst originating from the dental lamina.
Implications:
- This case highlights the importance of considering benign reactive hyperplasia in the differential diagnosis of pediatric gingival lesions with concerning histology.
- Successful surgical excision achieved a complete cure, avoiding the need for more aggressive cancer treatment.
- Understanding the histogenesis of PEH in this context may inform future diagnostic and management strategies for similar rare pediatric oral lesions.
