The calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm of mandible in adults. The presentation of this entity is varied and often confused with a variety of mucosal and jaw lesions and clinical, radiological, and pathological feature of CEOT often-mimic malignancy. The objective of this report is to highlight the clinical features and radiological findings which should arouse suspicion of a benign lesion and importance of providing adequate clinical information to the pathologist to attain accurate diagnosis.We discussed two cases with tumors located in the maxilla. Both presented as expansile lesions with one biopsy proven squamous cell carcinoma. Both were pursued with clinico-radiological suspicion of benign lesions and confirmed with pathological correlation of histology and immunohistochemistry as CEOT. Therefore a High index of suspicion and clinico-radiological information are the key feature for diagnosis of this rare tumor.
