Abstract
To elucidate the precise origin and characteristics of the epithelial components of osteofibrous dysplasia (OF) and adamantinoma (AD), the expression of transforming growth factor (TGF)-β1, β2 and β3 and cytokeratin (CK) subtypes were studied in five cases of AD and 18 cases of OF by immunohistochemistry. CK1 was expressed in 10 out of 18 OF cases; CK5 was expressed in one OF case; CK14 was positively stained in 10 cases of OF; CK19 was positively stained in 16 OF cases; CK1 was expressed in three out of five AD cases; CK5 was expressed in one case of AD; CK14 was positively stained in four AD cases; and CK19 was positively stained in five AD cases. In OF, TGF-β1, β2 and β3 were expressed in both fibroblasts and osteoblasts. In AD, TGF-β1, β2 and β3 were expressed in both epithelial and fibrous components. These results suggest that epithelial components of AD and OF share epidermal characteristics, CK1, express basal cell phenotype and cytokeratins 5, 14 and 19. In addition to these epithelial characteristics, strong immunoreactivity for TGF-β poses the possibility of TGF-β promotion of basal cell phenotype expression for the epithelial components in OF and AD.
