Amyloid-like material in odontogenic tumors.

Various types of odontogenic tumors (epithelial, mesodermal, and mixed tumors) were studied for the presence of amyloid material. Highman's Congo red and Wolman's standard toluidine blue methods were used for diagnosing amyloid. Of all types of odontogenic tumors studied, only the calcifying epithelial odontogenic tumors contained material that might be interpreted as amyloid-like.
