We present photometric and kinematic evidence for the presence of stellar disks, seen practically edge-on, in two Fornax dwarf galaxies, FCC 204 (dS0(6)) and FCC 288 (dS0(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 H0 = 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 Jergen et al. (2002) who discovered nucleated dEs with spiral and bar features in the Virgo Cluster.
