[Clinicopathologic analysis of glandular odontogenic cyst]

Glandular odontogenic cyst has been characterized only recently, and a few cases have been reported. In this report, seven cases were studied by clinical pathology. 6 cases were male and 1 was female. The average age of the patients was 36 years, with a range of 21 to 59 years. The majority of the cyst were located in maxilla. The fibrous capsule is usually free from inflammatory cells. The lining epithelium may be partly squamous and without distinctive features. However, in more or less extensive areas the stratified epithelium has a surface layer of acidophilic cuboidal or columnar cells, forming irregular papillary projections. Within the thickness of the epithelium there are crypts or cyst-like spaces lining by cells like those seen at the surface epithelium. In 1 cases a part of the lining epithelium has the features of mucoepidermoid carcinoma.
