Glandular odontogenic cyst.

Two cases of glandular odontogenic cysts are reported. The unique histological features, eg, the intraepithelial glandular structure, papillary processes, and eosinophilic cuboidal and larger granular superficial cells are sufficient to warrant glandular odontogenic cyst as a distinct entity. Electron microscopic examination of the superficial eosinophilic cuboidal cells are suggestive of a process similar to apoptosis. Eroded cortical plates suggest an aggressive behavior.
