We have identified 14 cases that over the last 40 years have been reported under a series of names, most commonly granular cell ameloblastic fibroma. An additional case in the mandibular premolar region of a 45-year-old woman is described. The tumor was conservatively removed and 4 years later shows no evidence of recurrence. On the basis of our examination of the clinical and histologic features of this lesion and a comparison with the previous cases, we agree with the recent suggestion that the tumor should be designated as a central odontogenic fibroma, granular cell variant. By means of S-100 protein immunostaining techniques, the granular cells in this lesion were compared with the granular cell population in a granular cell tumor (myoblastoma) and the mesenchymal component of an ameloblastic fibroma. The results reveal a lack of S-100 protein reactivity in the granular cells of the central odontogenic fibroma and suggest an origin of those cells different from the origin of cells in a granular cell tumor.

D009418 S100 Proteins A family of highly acidic calcium-binding proteins found in large concentration in the brain and believed to be glial in origin. They are also found in other organs in the body. They have in common the EF-hand motif (EF HAND MOTIFS) found on a number of calcium binding proteins. The name of this family derives from the property of being soluble in a 100% saturated ammonium sulfate solution.
