Which tumor is also known as a Pindborg tumor?

The correct answer is the calcifying epithelial odontogenic tumor, often referred to as a Pindborg tumor. This designation originates from the work of Dr. Arne Pindborg, who described the tumor's unique histopathological characteristics in the mid-20th century. The calcifying epithelial odontogenic tumor is known for its distinctive features, including the presence of sheets of epithelial cells, calcified deposits, and a clear pink-staining appearance due to the production of amyloid-like material.

This tumor is classified as an odontogenic neoplasm, meaning it arises from the tissues involved in tooth development. Understanding its nature and characteristics is crucial, primarily because it can be mistaken for other types of tumors or odontogenic lesions if the clinical and radiographic features are not carefully evaluated. The association with the term "Pindborg" helps underscore its unique pathology and historical significance in dental literature.
