Osteochondroma of the Coronoid Process and Joint Formation with Zygomatic Arch (Jacob Disease): Report of a Case
نویسندگان
چکیده
Jacob disease is a rare condition consisting of pseudo joint formation between enlarged mandibular coronoid process and the inner surface of the zygoma. We report a 16-years-old male patient with Jacob disease who presented with restricted mouth opening and swelling of the right zygoma. In this report, clinical, radiological, and histopathological findings of the Jacob disease and its surgical approach are discussed.

Osteochondromas are the most common benign bone tumor, most commonly found in the ends of long bones; however, they rarely involve facial bones, particularly the mandible. Osteochondromas involving the coronoid process have rarely been reported in the literature but pose a diagnostic dilemma. When large enough, osteochondromas of the mandibular coronoid process can form a joint with the zygomat...

Coronoid process hyperplasia was first described in 1853 by Von Langenbeck, and it was not until 1899 when Oscar Jacob described the disease that it was named after him. Jacobs's disease is an uncommon entity with only a few documented cases in...

Background Osteochondroma is a benign tumor that tends to develop in mandibular condyle and coronoid process in the craniofacial region. If tumor mass has grown from condyle into the infratemporal space with zygomatic arch obstructing the access, there are risks associated with surgical exposure and local resection of these masses. Case presentation This study reports on a case of osteochondr...
