Odontogenic cyst with diverse histopathological features: report of an unusual case.

ABSTRACT

OBJECTIVE: It is a well established fact that all inflammatory and developmental cysts of odontogenic origin have squamous epithelial linings. They may show various forms of metaplasia from a stratified squamous to more highly differentiated ciliated columnar or mucous cells. Dentigerous cyst represents is the most common developmental odontogenic cyst usually associated with an impacted tooth after complete formation of the crown. A dentigerous cyst encloses is seen attached to the neck of the tooth at the cementoenamel junction associated with an unerupted/ impacted tooth and grows by expansion of the dental follicles. We report a similar case of dentigerous cyst associated with an impacted tooth, histologically demonstrates the characteristics of a glandular odontogenic cyst with pseudo- stratified ciliated columnar epithelium lining with goblet cells and mucous cells.
