Glandular odontogenic cyst: report of a case and review of the literature.

The glandular odontogenic cyst is a rare jawbone cyst of odontogenic origin, first described in 1988 by Gardner et al. We describe a previously unreported case of a combined cyst composed of glandular odontogenic cyst and ghost cell keratinization that was present for 33 years. We also reviewed the published 38 cases of glandular odontogenic cyst found in the world literature and add this additional case.
