多数の埋伏歯を伴う上顎セメント質骨形成性線維腫の一例 A case of a cemento-ossifying fibroma associated with multiple impacted teeth arising in the right maxillary bone
We report a cemento-ossifying fibroma containing multiple impacted teeth within the tumor, which arose in the maxilla during infancy. The dental follicles of deciduous teeth were apparently involved in pathogenesis. The patient was referred to our hospital because of multiple impacted teeth in the right maxilla as well as spontaneous pain in the right maxillary first premolar region. CT scanning revealed a large mass in the right maxillary sinus, with six impacted teeth in the tumor. The biopsy diagnosis was a cemento-ossifying fibroma. The tumor was excised under general anesthesia. The size of the tumor was 50 × 40 × 35mm. Pathological examination confirmed a cemento-ossifying fibroma. The patient remains under observation, with no evidence of recurrence.
