| Research Abstract |
We examined the expression of all fibroblast growth factor receptors (FGFR1-4), their ligands (FGF1, 2, 9), and forkhead box N1 (FOXN1) in dermatofibroma (DF) and dermatofibrosarcoma protuberans (DFSP) by immunohistochemical analysis. Overexpression of FGFR3 and FOXN1 was observed in the epidermalregions of DF, and overexpression of FGF2 and FGFR4 was observed in the tumor lesions of DF. These expression patterns were in contrast with those of DFSP. We suppose tumor cells of DF may produce epigenetic changes in the epidermal regions of DF.
