Glandular odontogenic cyst
Discussion:
A well-delineated osteolytic lesion of the left mandible. The radiological differential includes odontogenic keratocyst and ameloblastoma.
Histological findings
- fragments of lamellar bone with surrounding osteoclastic activity
- occasional multinucleate giant cells are seen focally
- focally, there is a rim of fibrous tissue and is covered by attenuated squamous epithelium with focal areas of ciliated cuboidal type epithelium with areas of mucin vacuoles
- there is no corrugated parakeratinised squamous epithelium seen which is typically seen associated with an odontogenic keratocyst
Histological DDx: in view of the presence of ciliated cells, the differentials include periapical cyst, dentigerous cyst with ciliated metaplasia or nasopalatine cyst.
