Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign odontogenic tumor of locally aggressive behavior. It is more common in the posterior part of the mandible of adults, typically in the fourth to fifth decades. Its origin as well as its true malignant potential is not clearly known. It usually starts as a painless swelling and is often concurrent with an impacted tooth. A case of CEOT in a 55-year-old man with multiple myeloma is presented. Clinical, radiological, and pathologic findings are discussed.
