上顎洞に進展しセメント質様石灰化物を伴った歯原性粘液腫の1例 A case of a large odontogenic myxoma containing cemento-like calculi in the maxillary sinus
A patient with a large odontogenic myxoma of the maxilla is described. A 13-year-old boy was referred to our hospital because of a swelling in the maxilla. Radiographic and computed tomographic examinations showed a well-demarcated tumor in the maxillary sinus that contained small calculi and was associated with extensive resorption of maxillary bone. Histological examination revealed that the tumor consisted of spindle-shaped cells with no atypia in the myxomatous connective tissue. Scattered cement-like small calculi were present. An odontogenic myxoma was diagnosed. The tumor was extirpated by an intraoral approach. There has been no evidence of recurrence 18 months after surgery.
