Abstract: Fibrous dysplasia (FD) and aneurysmal bone cyst (ABC) are two different entity, with different pathophysiological mechanisms. FD is a benign fibro-osseous lesion characterized by a fibrous replacement of the medullary component of bone. The second lesion, ABC, is an expansive osteolytic lesion consisting of blood-filled spaces. The coexisting and association of these two disorder is unusual. We report a case of a 12 year old patient presenting with both FD and ABC in the left mandibular area, and managed surgically in the oral surgery department of the dental consultation and treatment of Casablanca .
