<unk>  <unk>  is a rare developmental lesion that comes from odontogenic epithelium. It is also known as a<unk>  cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It can appear in any location in the oral cavity, but more commonly affects the anterior (front) mandible and maxilla. It is most common in individuals in their 20s to 30s, but can be seen at almost any age, regardless of gender. On dental radiographs, the<unk>  appears as a unilocular (one circle) radiolucency (dark area). In one-third of cases, an impacted tooth is involved. Histologically, cells that are described as "ghost cells", enlarged eosinophilic epithelial cells without nuclei, are present within the epithelial lining and may undergo calcification.
