Osteomas are benign tumors that consist of mature, compact, or cancellous bone. Osteomas that arise on the surface of bone are referred to as periosteal osteomas; whereas, those that develop centrally within bone are endosteal osteomas. Osteomas are rare benign tumors of bone commonly occurring in the maxillofacial skeleton. Most jaw osteomas occur in young adults and are generally asymptomatic, sessile, and solitary lesions. There is seldom any pain associated with this tumor. We herewith report a case of pedunculated osteoma arising from angle of mandible in an elderly lady.

| Introduction|| |
Osteomas are benign tumors that consist of mature, compact, or cancellous bone;  and can be of a peripheral, central, or extraskeletal type. , There is seldom any pain associated with this tumor.  Osteoma arises from the craniomaxillofacial region, such as the sinus, temporal bone, or jaw bone. , Osteomas that arise on the surface of bone are referred to as periosteal osteomas; whereas, those that develop centrally within bone are endosteal osteomas.  Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. ,, Peripheral osteoma of the mandible is relatively uncommon,  and arise from the mandibular body, angle, condyle, or coronoid process. , An elderly lady aged 53 presented with pedunculated osteoma arising from the angle of the mandible , of 8 years duration.
| Case report|| |
A 53-year-old lady presented with a swelling of 8 years duration in the parotid region, progressively increasing in size for the past 2 years. She complained of pain while chewing hard objects. On local examination, 8 × 6 cm stony hard swelling was present in the parotid region lifting the right ear lobe. Peroral examination revealed no significant pathology.
On X-ray, a radiopaque, dense, bony lesion arising from the angle of mandible was noted [Figure 1]. Fine needle aspiration cytology (FNAC) attempted twice showed only formed elements of blood. The tumor was surgically excised and sent for histopathologic examination [Figure 2].
Postoperative was uneventful and the patient recovered well [Figure 3].
Pedunculated stony hard mass measuring 8 × 6 cm with a pedicle attached to it at the base [Figure 4].
Sections showed broad trabeculae of mature lamellar bone with prominent cement lines [Figure 5].
| Discussion and conclusion|| |
Osteomas are benign tumors that consist of mature, compact, or cancellous bone;  and can be of a peripheral, central, or extraskeletal type. , There is seldom any pain associated with this tumor.  Peripheral osteoma of the jaw is an osteogenic benign lesion of slow growth, which can be or not pedunculated. , Peripheral osteomas are normally an incidental finding and they are asymptomatic, depending on the location and the size of the lesion, it can cause facial deformity, deviation of the mandible on opening, headache, bone pain, dysphagia, or exophthalmos. The most common symptom is pain  and in this case the patient complained of pain while chewing hard substances.
In the literature, case reports publishing osteomas in the mandible include 23 cases located in the body (four cases in the anterior region and 19 cases in the posterior region) followed by the condyle (18 cases), angle (nine cases), ascending ramus (seven cases), coronoid process (five cases), and sigmoid notch (one case). 
This female patient aged 53 years presented with pain on chewing hard substances and the swelling was present on the angle of the mandible which is pedunculated and the duration was of 8 years.
After 5 months from the postoperative day till to date, the patient is fine and there is no recurrence [Figure 6].
