Extraosseous calcifying epithelial odontogenic tumor (Pindborg tumor)
International Journal of Oral Surgery
|October 1, 1977
Summary
A rare clear cell variant of a calcifying epithelial odontogenic tumor, also known as Pindborg tumor, was diagnosed in a young man. This extraosseous tumor presented as painless gingival enlargement without bone involvement.
Area of Science:
- Oral pathology
- Odontogenic tumors
- Neoplasms
Background:
- Calcifying epithelial odontogenic tumor (Pindborg tumor) is a rare benign odontogenic neoplasm.
- Clear cell variants are exceptionally uncommon.
- Extraosseous presentation without bone involvement is unusual.
Observation:
- A 20-year-old male presented with painless, non-osseous enlargement of the maxillary gingiva.
- Microscopic examination and special stains were utilized for diagnosis.
Findings:
- The diagnosis was confirmed as a clear cell variant of a calcifying epithelial odontogenic tumor.
- This represents the second reported case of an extraosseous clear cell variant.
Implications:
- Highlights the diverse clinical presentations of Pindborg tumors.
- Emphasizes the importance of microscopic examination for diagnosing rare variants.
- Contributes to the limited literature on extraosseous clear cell odontogenic tumors.
