Abstract

Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type. Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. Solitary peripheral osteomas are characterized by well-defined, rounded, or oval radiopaque mass in the computed tomography. Although multiple osteomas of the jaws are a hallmark of Gardner's syndrome (familial adenomatous polyposis), nonsyndromic cases are typically solitary. Herein, we report a rare case of solitary peripheral osteoma of the angle of the mandible in a 27-year-old female with clinical, radiologic, and histopathologic findings.

Summary

Introduction

Solitary peripheral osteomas of facial bones are benign osteogenic tumors characterized by the proliferation of compact or cancellous bone. They originate from the craniomaxillofacial region such as temporal bones, sinuses, or maxilla or mandible. Multiple osteomas of jaws are a hallmark of Gardner’s syndrome (familial adenomatous polyposes), an autosomal dominant disease caused by a mutation in the APC tumor suppressor gene In this syndrome, patient presents with multiple osteomas of the jaws along with multiple premalignant colorectal adenomas, which if left untreated progresses to colorectal carcinoma by middle age [3]. We present a case of a solitary peripheral osteoma arising at the angle of the mandible with its clinicopathological and radiological findings along with differential diagnosis and treatment plan
