Abstract
A case of aneurysmal bone cyst (ABC) of the mandible, recurring for the third time and arising in conjunction with fibrous dysplasia, is reported. A comprehensive review of the literature and analysis of over 50 cases of ABC of the jaws yielded the following results: ABCs of the jaws constitute 1.5 % of all non-odontogenic and non-epithelial cysts of the jaws, and 1.9 % of all ABCs of the skeleton. The mandible was affected in 55 % of the cases, the maxilla in 45 % of the patients. Females represented 53 % of the patients and males the remaining 47 %. Seventy-four percent of the ABCs occurred in patients 20 years old and younger. This lesion is regarded as non-neoplastic and as most likely secondary to a pre-existing bone lesion. Our review established that 21 % of the reported cases in the jaws had developed in association with various primary lesions of bone, including fibro-osseous lesions. The primary bone lesion initiates an osseous, arteriovenous fistula which, through its hemodynamic forces, creates a secondary reactive lesion, that is an aneurysmal bone cyst. We also established a recurrence rate of 26 %, based upon previously reported cases as well as our own. The treatment of choice is surgical curettage with cryosurgery and immediate packing with bone chips.
