Mandibular dentinoma.
Summary
This case study details a rare dentinoma, an odontogenic tumor, in an 11-year-old male. Surgical removal was successful, with no recurrence observed in the initial 10-month follow-up period.
Area of Science:
- Oral pathology
- Odontogenic tumors
- Dentinoma
Background:
- Dentinoma is a rare odontogenic tumor characterized by inductive interactions between odontogenic epithelium and connective tissue.
- Understanding the histological and immunohistochemical features of dentinoma is crucial for accurate diagnosis and management.
Observation:
- A case of dentinoma is presented in an 11-year-old male, associated with a missing right mandibular second permanent premolar.
- The tumor and an impacted deciduous molar were surgically excised.
- Histological examination revealed varying stromal maturity, osteodentin, tubular dentin, and hyalinized collagen areas.
Findings:
- Immunostaining demonstrated negative results for types I, III, and IV collagens in hyalinized areas.
- Type IV collagen was observed as a halo around odontogenic epithelial cells, indicating basal membrane presence.
Implications:
- This case contributes to the limited literature on dentinoma, offering insights into its histological presentation.
- The findings highlight the importance of immunohistochemistry in characterizing tumor components and understanding their origins.
- Successful surgical management and monitoring for recurrence are key in cases of dentinoma.
