BOTRYOID ODONTOGENIC CYST IN THE MAXILLA

Abstract

A 53-year-old woman presented an asymptomatic lesion in the anterior maxilla, causing a discrete bone expansion and covered by healthy oral mucosa. Cone beam computed tomography showed coalescent and well-defined hypodense areas at the periapical region of teeth 11, 12, and 13, measuring 12 mm, with buccal cortical bone discontinuity. The diagnosis hypothesis of an odontogenic cyst was confirmed by microscopic examination after incisional biopsy. The lesion was enucleated and tooth 12 was removed. The surgical specimen analysis revealed multiple cystic spaces lined by a thin, nonkeratinized epithelium with plaquelike thickenings. Some clear cells were noticed. The cystic wall was of a fibrous connective tissue. The final diagnosis was of botryoid odontogenic cyst. After 9 months of follow-up, there are no clinical or radiographic signs of recurrence.
