Jacob’s disease secondary to coronoid process osteochondroma. A case report

The formation of a new joint between a pathologically elongated coronoid process and the body of the malar homolateralbone is known as Jacob’s disease.Coronoid process hyperplasia was first described in 1853 by Von Langenbeck, and it was not until 1899 whenOscar Jacob described the disease that it was named after him. Jacobs’s disease is an uncommon entity with onlya few documented cases in the literature. The condition first manifests with progressive limitation of mouth openingand facial asymmetry. Pain is uncommon and it mainly affects young patients. Different factors have beenpostulated as possible causes, including temporal muscle hyperactivity, previous trauma, chronic disc displacementof the ipsilateral temporomandibular joint, endocrine stimuli, and genetic alterations. Definitive diagnosis isby histopathology and it is necessary to confirm bone hyperplasia, the presence of cartilage and synovial capsuleforming the new joint between the malar bone and the coronoid process. We report a 52-year-old woman patientwith a history of childhood trauma in the right preauricular region. She came to our department with a 2-yearhistory of progressive limitation of mouth opening. Computed tomography (CT) revealed a right coronoid processelongation, in contact with the homolateral malar bone, causing it to deform. Surgery with general anesthesia wasperformed using an intraoral vestibular approach. Histopathology confirmed the diagnoses of Jacob’s disease (AU)
