Periosteal Chondroma of Mandible: Report of a Case and Differential Diagnosis

Cartilaginous tumors make up the second largest group of bone neoplasms. These are common in the long bones of the body. Chondromas among them are mostly painless, intraosseous lesions with presence at both endosteal and periosteal location. They are relatively rare in jaws owing to their membranous development and are reported to occur in cartilage bearing areas of jaws. This article is aimed at presenting a case of periosteal chondroma in mandibular premolar region with an emphasis on its histogenesis and differential diagnosis because of its similarity with some other exophytic bony lesions in the area.
