Abstract
Calcifying epithelial odontogenic tumor (CEOT) is a benign tumor of odontogenic epithelium.It is a locally invasive neoplasm with a characteristic feature of having amyloid. The mandible is twice more commonly affected than the maxilla and in the maxilla, posterior location is the preferred site of involvement. Here we present a case in a 50 years old male patient who presented with a non-tender hard swelling of the anterior maxilla measuring 2.5 x 1.5 cm, just right to the midline and at the base of the lateral incisor and canine. Imaging revealed a radiolucent lesion in the maxilla with small foci of calcification without any evidence of impacted tooth. Thus a provisional diagnosis of an Ameloblastoma was made. A local excision of the swelling was done along with extraction of the lateral incisor and canine. On histopathological examination, a diagnosis of Calcifying epithelial odontogenic tumor was rendered.DOI: 10.21276/aohdr.1807

Calcifying epithelial odontogenic tumor (CEOT) is a benign tumor of odontogenic epithelium,first described by the Danish pathologist, Dr Jens J
Pindborg in 1955.1CEOT is listed as a benign tumor of odontogenic epithelium with mature fibrous stroma without odontogenic mesenchymeby World Health Organization.2It is a “locally invasive neoplasm with a characteristic feature of having amyloid which tends to calcify”.2The origin of CEOT is said to arise from the enamel organ’s stratum intermedium in the tooth development stage, a few believe that they may arise from the remnants of the dental lamina of initial stages of odontogenesis.[3]
An intra-oral examination revealed a firm to hard swelling of the anterior maxilla, just right to the midline and at the base of the lateral incisor and canine
Summary
Calcifying epithelial odontogenic tumor (CEOT) is a benign tumor of odontogenic epithelium,first described by the Danish pathologist, Dr Jens J. Pindborg in 1955.1CEOT is listed as a benign tumor of odontogenic epithelium with mature fibrous stroma without odontogenic mesenchymeby World Health Organization.2It is a “locally invasive neoplasm with a characteristic feature of having amyloid which tends to calcify”.2The origin of CEOT is said to arise from the enamel organ’s stratum intermedium in the tooth development stage, a few believe that they may arise from the remnants of the dental lamina of initial stages of odontogenesis.[3]. An intra-oral examination revealed a firm to hard swelling of the anterior maxilla, just right to the midline and at the base of the lateral incisor and canine. A local excision of the swelling was done alongwith extraction of the lateral incisor and canine, and the specimen sent for histopathological examination. There are numerous amorphous pale eosinophilic rounded masses of amyloid like material, with few showing calcification, and surrounding acute on chronic inflammatory infiltrate (Fig-1). the tumor was diagnosed as CEOT of right anterior maxilla.
