We present photometric and kinematic evidence for the presence of stellar disks, seen practically edge-on, in two Fornax dwarf galaxies, FCC 204 (dSO(6)) and FCC 288 (dSO(7)). This is the first time such structures have been identified in Fornax dwarfs. FCC 288 has only a small bulge and a bright flaring and slightly warped disk that can be traced out to +/-23 from the center (2.05 kpc for H-0 = 75 km s(-1) Mpc(-1)). FCC 204's disk can be traced out to +/-20 (1.78 kpc). This galaxy possesses a large bulge. These results can be compared to the findings of Jerjen et al. (2000) and Barazza et al. (2002) who discovered nucleated dEs with spiral and bar features in the Virgo Cluster.
