Calcifying epithelial odontogenic tumor (CEOT) in palate: report of a case

A calcifying epithelial odontogenic tumor (CEOT) was first described as a separate entity in 1955 by Pindborg, and has since been referred to as Pindborg tumor. CEOT is characterized by the presence of squamous-cell proliferation, calcification and amyloid deposits, and accounts for only 1% of all odontogenic tumors. CEOT is a benign, though occasional locally invasive, slow-growing neoplasm. It is located either intraosseously or extraosseously, and is usually associated with an unerupted permanent tooth. A 24 year-old female visited our clinic, presenting with a palatal swelling and intra-oral ulcer. After an incisional biopsy, the lesion was confirmed to be odontogenic tumor. A tumor resection and reconstruction surgery with tongue flap were performed.
