Osteochondroma at the angle of mandible: A rare case

Abstract

Osteochondroma (OC) is one of the most common benign tumor of osseous and cartilaginous origin. It usually occurs in the skeletal bones and very rarely in craniofacial region. In the craniofacial region, condyle and coronoid process of the mandible are the most commonly affected areas. The present article reports the extremely rare case of OC arising from the angle of the mandible causing facial asymmetry.

An unusually large osteochondroma of the mandibular angle: a case report

“…OCs of the mandibular region are rare, with 38 cases of OC involving the mandibular condyle, 49 involving the coronoid process, and a handful involving the maxilla reported [ 4 – 6 ]. Moreover, OCs of the mandibular body are extremely uncommon; indeed, to the best of our knowledge, only four cases of OC of the mandibular angle, other than our own, have been reported, and the present case represents the largest such tumor ever reported [ 7 ].…”

A Case Report and Review on Mandibular Compact and Cancellous Osteomas

“…Histologically, they are composed of malignant osteoblasts with hyperchromatic nuclei admixed with some spindle shaped cells producing atypical eosinophilic osteoid and giant cells in a rich fibrovascular connective tissue stroma [20]. Osteochondromas are benign tumors of osseous and cartilaginous origin arising from the cortical bone and characterized by the presence of bony trabeculae enclosed with a cartilaginous cap [21]. Thus, we ruled out the possibility of all the osseous lesions enlisted in our differential diagnosis on the basis of their unique radiological, CT and histological features to finally diagnose our both cases as osteoma.…”

Osteochondroma of the mandibular angle: Report case and literature review

“…Others authors refute that these approaches can make a complete exposure of the tumor to make the resection. The disadvantages of the submandibular approach are the risk of damage to the mandibular branch of facial nerve and a scar submandibular [4].…”

“…The advantage is to provide a direct access to the lesion without damaging the facial nerve and leave blemishes [4].…”

“…The mandibular angle is a rare location [2]. Only three cases of osteochondroma in mandibular angle have been reported previously in literature [3,4]. Osteochondroma may present in solitary form or as multiple osteochondromas, syndrome known as osteochondromatosis [5].…”
