An odontogenic tumor was examined by means of the light and electron microscope. The findings of the authors and those in the literature suggest that ameloblastoma fibromatosum is a more differentiated tumor than ameloblastoma simplex. The basement membrane of an ameloblastoma fibromatosum is intact. This distinguishes it from the ameloblastoma cysticum, ameloblastoma acanthomatosum and carcinoma basocellulare. The epithelial component of the tumor is surrounded by a homogenic zone. Electron microscopically it shows a heterogenic structure. Most probably it consists of glycoprotein. It is assumed that the latter could be the precursor of dentin.
