SANDER KOTH, Valesca et al. A rare presentation of central granular cell odontogenic tumor. Rev. Estomatol. Herediana [online]. 2021, vol.31, n.2, pp.125-130. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v31i2.3973.

The central granular cell odontogenic tumor (CGCOT) is a rarely seen neoplasm of odontogenic origin with a predilection for mandible of middle aged women. The lesion shows slow growing and radiographic feature of a radiolucent unilocular lesion with a radiopaque border. The present study aims to report a new case of CGCOT with an atypical involvement of anterior maxilla. Clinical exam showed swelling of the hard palate and the vestibular area of left canine and pre-molar of maxilla. Cone beam computed tomography showed a hypodense unilocular well delimited lesion extending from central left incisive to left pre-molar region. Histopathological analysis showed granular eosinophilic cells and islands of odontogenic epithelium and positive immunostaining for CK14, vimentin, CD68, Ki67 and S-100, which established the diagnosis of CGCOT. The patient is under follow-up without recurrence for sixteen months.

Palabras clave : Neoplasm; neoplasms by histologic type; vimentin; granular cell odontogenic tumor; radiographic study.
