Strictly speaking, the aneurysmal bone cyst is not a true cyst. It is a lesion characterized by replacement of bone by fibro-osseous tissue containing blood-filled cavernous spaces. It is usually treated by surgical curettage, and access within the jaws may sometimes be difficult. We reviewed the world literature and found 63 cases of aneurysmal bone cysts involving the face, 22 reported in the maxilla, and 63 in the mandible. One was found in the zygomatic arch. Of the patients reported, 88% were younger than 30 years old; there was an equal sex distribution. Included in this report, are two cases of our own, one involving the maxilla and one the mandible.

    ABSTRACT: An aneurysmal bone cyst of the maxilla is a nonneoplastic, uncommon, solitary bone lesion recognized by distinct radiographic and histopathological characteristics. It is described as a localized and quickly expandable benign tumor, which can reach a considerable size. It is characterized by the replacement of bone by spongy fibro-osseous tissue and a locally destructive and multicystic lesion filled with blood. It is attributed to a circulatory disturbance leading to locally increased venous pressure but with an unclear etiology. It takes place mainly in the long bones and in patients less than 20 years old, with no sex predilection. Its treatment is by surgical excision. An aneurysmal bone cyst in the facial bone is rare. The present case describes the lesion arising in the maxilla of a 14-year-old girl.
