We report a rare case of central Schwannoma, a type of nerve sheath tumor, arising in the mandibular bone of a 34-year-old man. A periapical lesion was discovered during routine dental treatment. Radiographically, the lesion was a large round-shaped and well-defined radiolucent lesion with a radiopaque rim in the anterior apical region, which extended from the right canine to the left lateral incisor in the mandible. The surgically removed mass was a relatively well-encapsulated tumor, measuring 1.5 cm in diameter. Histologically, the tumor showed a typical histology of Antoni type A of Schwannoma, focally interspersed with myxoid areas in which tumor cells had nuclear atypia. A review of the literature revealed that there have been only a total of 54 reported cases of central Schwannoma of the jaw bones including the present case, most of which were located in the posterior part of the mandible with a female/male ratio of 1.6 to 1 and a mean age of 33.9 years.
