Attempt to characterize the lining of the cyst. Look for important signs:
Any keratinization of the lining.
Any signs of malignancy. Further information: Evaluation of suspected malignancies
All the following are odontogenic cyst, and in case of inability to specify further, may be simply diagnosed as such:
|Cyst type||Lining epithelium||Other characteristics||Image|
|Periapical (radicular) cyst||Stratified squamous epithelium of variable thickness, except when originating in a maxillary sinus where there is respiratory epithelium (pseudostratified ciliated columnar epithelium).||
They sometimes have the following features:
|Non-inflamed dentigerous cyst||Typically:
They occasionally have:
|Inflamed dentigerous cyst||Hyperplastic non-keratinized epithelium||Typically:
They occasionally have:
|Residual cyst||Stratified squamous epithelium:
In early cysts, the epithelial lining tend to be proliferative and arcading, with an intense inflammation.
|Cyst lumen may demonstrate fluid and cellular debris.|
All types above can occasionally have scattered mucous or ciliated cells, as well as Rushton bodies, which are amorphic, eosinophilic, linear to crescent-shaped bodies in the cyst epithelium.
- Type of lining
- Other visible features
- At least the most probable type of cyst.
- Even absence of signs of malignancy
- Benign odontogenic cyst of periapical type.
