Botryoid odontogenic cyst: analysis of 33 cases

The botryoid odontogenic cyst is considered to be a multiloculated variant of the lateral periodontal cyst. Fewer than 40 of these lesions have been described, many of which have recurred. This paper describes the demographic, clinical, microscopic, and radiographic features of 33 unreported cases from the files of the Oral Pathology Biopsy Service at the University of North Carolina School of Dentistry. Our findings are in agreement with previously published cases for an average age of 57 years and the most common site for occurrence in the lower premolar area. Follow-up information on 12 patients determined that 2 had recurrences.
