Granular cell odontogenic tumor: report of a rare case and a review of literature.

BACKGROUND: Granular cell odontogenic tumor (GCOT) is a rare neoplasm with about 45 cases reported in the literature. It usually occurs in the posterior mandible of middle-aged women. CASE PRESENTATION: We report a case of asymptomatic GCOT in the posterior mandible of a 28 years old female and provide a literature review of GCOT cases. Some unusual features such as root resorption, displacement of inferior tooth canal, and multilocular appearance were considerable in this case. CONCLUSIONS: Complete surgical excision of the lesion was beneficial for the patient.
