Aneurysmal Bone Cyst of the Jaws: Clinicopathological Study

Abstract

Aim: The aim of the present study was to analyze clinical, radiological and histopathological features of aneurysmal bone cysts (ABCs) of jaws. Materials and Methods: Archival data from 2009 to 2012 present in the Oral Pathology Department was retrieved and clinicopathological features of all the cases which had been previously diagnosed as ABC were analyzed in detail. Results: Seven cases ranging in age from 10 to 50 years were included, in which maximum (5/7) cases were below 20 years. Ratio of presentation of lesion in male to female and in maxilla to mandible was 3:6 and 1:6 respectively. Swelling and pain were the most common presenting features. Variable presentation of the lesion was observed radiographically; although multilocular, well defined, bone expansion and perforation were the most common observations. Histopathological analysis revealed association of one case with ossifying fibroma and two cases with trabecular variety of juvenile ossifying fibroma. Predominance of solid variety was noted and other features like stroma, giant cells, nature of blood vessels, bone destruction and perforation and presence of any osteoid or calcified material was also accounted for. The current study showed association of two cases with trabecular variety of juvenile ossifying fibroma, which is a rare finding. Conclusion: ABCs of jaws, thus have varying patterns of presentation which are diagnostically challenging. A thorough examination of the incisional/excisional tissue is thus required to confirm the association with any other lesion which will affect the treatment plan for the patient.
