DECOMPRESSION FOLLOWED BY CRYOSURGERY FOR TREATMENT OF A GLANDULAR ODONTOGENIC CYST

The glandular odontogenic cyst (GOC) is a rare developmental cyst. Clinically, there is a slow growth without symptoms; radiographically, it is usually characterized as a radiolucent lesion, unilocular or multilocular, with well-defined borders, and an aggressive behavior. This clinical case aims to report on a woman, 50 years old, who presented herself with a history of 5 months’ of volume increase in the right side of her mandible, without pain. Radiographically, we observed a radiolucent area between tooth 41 to 45. An incisional biopsy was performed with inconclusive histopathologic diagnosis. In a second exam, we installed a drain for decompression. The histopathologic diagnosis was a GOC demonstrating epithelium and structures similar to ducts. After 6 months, the cyst diminished and distanced itself from the mental nerve. The lesion was enucleated, and the patient underwent a cryosurgery on the remaining walls to avoid relapse. There is no signal of recurrence after 2 years.
