Intraosseous lipoma appears less frequently in the maxilla than in the mandible. The initial phase of tumor development is characterized by asymptomatic growth, followed by the presence of pain and paresthesia in the later stage. We report the case of a 43-year-old female patient who contacted a doctor because of periodic pains and stupor in the left side of the upper jaw. The exostosis-like formation was found by palpation, subsequently raising suspicion of an odontogenic tumor on the basis of panoramic imaging (dental orthopan). The intraosseous lipoma was histopathologically diagnosed after surgical procedure and standardized treatment of removed tumefaction. Clinical features and x-ray findings of the intraosseous lipoma within the maxillary region are generally blurred. Surgery is the recommended treatment, and histopathology analysis is of utmost importance for the final diagnosis.
