A Case Report of Primordial Odontogenic Tumor That Required Distinction from a Dentigerous Cyst

Primordial odontogenic tumor (POT) is a rare characterized by variably cellular loose fibrous tissue with areas similar to the dental papilla and covered cuboidal columnar epithelium. We herein report case of POT in 14-year-old boy. Computed tomography (CT) exhibited round cavity defined cortical border circumscribing tooth second molar. However, gross finding was solid mass, not cyst. Histologically, consisted papillalike myxoid connective Therefore, although clinical diagnosis dentigerous cyst (DC), we diagnosed based on histologic findings. Clinical findings resemble DC, but behavior different such as expansion root resorption teeth. histological differentiation from DC critical for accurate diagnosis.
