92歳の女性に生じた石灰化囊胞性歯原性腫瘍の1例

Calcifying cystic odontogenic tumor is a comparatively rare tumor that often occurs in young people. Histopathologically, it is characterized by odontgenic epithelium and ghost cells with calcification. We report a case of calcifying cystic odontogenic tumor occurring in the mandible of an elderly woman, along with a discussion of the literature. A 92-year-old woman noticed swelling and pain at the left molar region of the mandible about 2 years before presentation. Because the swelling recurred several times after incisional drainage performed at a nearby dental clinic, she visited the department of oral and maxillofacial surgery of another hospital. Biopsy with histopathological examination revealed a calcifying cystic odontogenic tumor, and she was referred to our hospital. She was edentulous and had a bone-like firm bulge extending from the left molar region to the front of the ramus. Panoramic photography and computed tomography showed a radiolucent image with a clear border in the region. The tumor was surgically resected under sedation and local anesthesia. There has been no recurrence during the 15 months of follow-up.
