Microscopic examination
Attempt to characterize the lining of the cyst. Look for important signs:
Signs
Any keratinization of the lining.
Any signs of malignancy. Further information: Evaluation of suspected malignancies
Diagnoses
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).[1] |
They sometimes have the following features:[1]
|
|
Non-inflamed dentigerous cyst | Typically:[2]
They occasionally have:
|
||
Inflamed dentigerous cyst | Hyperplastic non-keratinized epithelium[2] | Typically:[2]
Sometimes:[2]
They occasionally have:[2]
|
|
Residual cyst | Stratified squamous epithelium:[5]
In early cysts, the epithelial lining tend to be proliferative and arcading, with an intense inflammation.
|
Cyst lumen may demonstrate fluid and cellular debris.[5] |
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.[4][1][2][5]
Report
- Type of lining
- Other visible features
- At least the most probable type of cyst.
- Even absence of signs of malignancy
Example:
Parts of a cyst, lined by stratified squamous epithelium, with foci of mucous cells and ciliated cells. The underlying fibrous capsule contains cholesterol clefts and inflammation. No signs of malignancy. - Benign odontogenic cyst of periapical type. |
