Final Diagnosis:
PERIPHERAL-DENTINOGENIC GHOST CELL TUMOUR
- Quite rare
- The usual presentation is a nodular non-specific swelling
- Share same histopathological features as their intraosseous counterpart
Treatment
- Conservative excision is an appropriate treatment
- Rare recurrence
Take-Home Message
- This lesion seems to be less aggressive than its central counterpart with rare recurrences after simple excision
- Special care must be taken to distinguish dentinogenic ghost cell tumour from ‘ameloblastoma with ghost cells’:
- The proportion of ghost cells (> 1-2%) and the presence of dentinoid are important features in establishing the diagnosis of this entity
