Cisto odontogênico glandular: relato de caso

Abstract

Glandular Odontogenic Cyst (GCO) is a rare benign odontogenic lesion that was first described in 1987. It is defined as a cyst arising in the areas of eruption of teeth in both arches, characterized by an epithelium formed by cuboid or columnar cells, both on the surface and crypts within the thickness of the epithelium.It occurs more frequently in the anterior region of the mandible, in adults over 40 years of age, predisposed by the male gender. It tends to recur, has slow growth and appears as an asymptomatic swelling of the jaw. This report presents a case of a male patient, 58 years old, who was referred to the University after attending a private practice for rehabilitation with implant prosthesis.The lesion was discovered in the panoramic radiography for implant planning. An intraoral clinical examination revealed right mandibular swelling.In panoramic and cone beam computed tomography images, a radiolucent, unilocular and well definedlesion was observed, extending from the midline region to the first right lower first molar. Incisional biopsy and marsupialization of the lesion were performed, obtaining the diagnosis of glandular odontogenic cyst. After five months, enucleation and curettage of the lesion were performed. Three months after enucleation, a new CBCT scan was performed and it could be observed new bone formation in the region, with no evidence of recurrence. The patient is followed up every six months in the oral diagnosis clinic.
