Odontogenic myxoma

Overview
The odontogenic myxoma is an odontogenic tumor arising from the dental papilla. It is more common in young adults and affects the mandible more than the maxilla. Usually, the odontogenic myxoma is painless but can cause a swelling. On radiographs, it appears as a multilocular radiolucency (dark area) with short, straight trabeculae. As a result, this appearance is usually described as "honeycomb-like".
