Odontogenic tumors develop in the jaws from odontogenic tissues such as enamel organ, Hertwig epithelial root sheath, dental lamina, and so on. A variety of tumors unique to the maxilla and mandible are therefore seen. Calcifying epithelial odontogenic tumor (CEOT) is a rare, aggressive, benign odontogenic tumor of epithelial origin accounting for only about 1% of all odontogenic tumors. It is eponymously called "Pindborg tumor", as it was first described by Pindborg in 1955. The origin of this locally invasive tumor remains unknown. It is thought to arise from stratum intermedium. It commonly affects the posterior mandible manifesting as a slow-growing asymptomatic swelling often associated with an impacted tooth. We report a case of CEOT, for which, owing to its huge size we have proposed the term "giant" Pindborg tumor (CEOT). This is probably the largest case of this tumor reported so far in the English literature. The present case also has the classic yet rare "driven snow" appearance of the tumor on radiographs.
