Glandular odontogenic cyst. Report of seven cases.

This study describes the clinical, radiographic and histopathological features of seven glandular odontogenic cysts. These cysts comprised 0.012% of 5800 jaw cysts diagnosed in a 19-year period. There was strong predilection for the mandible (five of the seven cases). Both clinical and radiographic features were nonspecific. The main histological findings were a nonkeratinized, stratified squamous epithelium lining to the cyst cavity which varied in thickness with superficial eosinophilic cuboidal cells and mucous pools within the spinous cell layer. Daughter cysts were found in the wall of 2 cysts. At surgery, most walls were found to be thin and lumen to contain a serous, low viscosity exudate. Because of the high rate of recurrence found in three cases out of the seven after conservative surgical treatment, careful clinical and radiographic follow-up is recommended.
