Aneurysmal bone cyst (ABC) is a rare benign lesion of bone, which represents less than 1% of all the bone cysts biopsied.  It is generally noted in long bones and spine and is less common in the craniofacial skeleton including maxilla and mandible. These rare jaw lesions are encountered mostly in the body and ramus of the mandible in the second or third decades of life. This case report describes a rare case of ABC in a 48 year old male patient involving the left body and ramus of the mandible. Clinically, it presented as an extra-oral swelling of 3 months duration with occasional mild pain and paraesthesia of the lip which are rare features of the lesion. Both conventional and CT imaging were suggestive of a multilocular (soap-bubble) lesion.  An incisional biopsy was done and the histopathological report was suggestive of an Aneurysmal Bone Cyst. The patient was planned for hemimandibulectomy with free fibula reconstruction graft.
