Odontogenic cysts: classification, histological features and a practical approach to common diagnostic problems

The epithelial remnants of tooth development give rise to an impressive range of cystic lesions, termed odontogenic cysts.

Description
Summary:The epithelial remnants of tooth development give rise to an impressive range of cystic lesions, termed odontogenic cysts. They are classified based on their distinct clinical, radiological and histological features, a process that has not been without controversy. We will attempt to explain the basis of the debate behind the changing classification of odontogenic cysts, describing their aetiology, clinical and histological features, along with common pitfalls that can confuse the diagnostic process. More common diagnostic challenges, such as the effects of inflammation and mucous change, will be explored in detail. An attempt will be made to distil the diagnostic process into simple algorithmic steps to narrow down the differential diagnoses of this fascinating group of lesions. We will demonstrate the importance of careful consideration of the clinical and radiological features that can help prevent misclassification, ensuring appropriate management and follow-up for this diverse group of lesions.
