We report a case of squamous odontogenic tumor with multilocular radiolucency in the mandible, which is a rare benign odontogenic tumor. A 72-year-old man noticed painless swelling in the anterior part of the mandible. On radiographs the mass showed multilocular radiolucency. The clinical diagnosis of ameloblastoma was reached, and then excision of the tumor tissue was performed with the patient under general anesthesia. Histopathological examination of the specimen revealed uniformly dispersed islands of squamous epithelium in the dense connective tissue stroma. Based on these findings, the lesion was diagnosed as a squamous odontogenic tumor. As of 1 year 6 months after the operation, no sign of recurrence has been observed.
