The azimuthally averaged surface brightness profiles of 200 faint early-type Virgo cluster galaxies have been analyzed. Faint dwarfs are very well described by an exponential or a King model. The magnitudes of the nuclei vary greatly at a given galaxian magnitude, but the maximum nuclear luminosity is a strong function of M(T). In the 0.1-1 kpc radius range, the logarithmically plotted profiles of all early-type galaxies come in two well-defined classes identified with classical types versus dwarf types. The former are all classified E or S0, while the latter comprise all galaxies classified dE or dS0, all morphologically 'intermediate' types, and even two classified 'E'. The mean SB profiles of dS0 galaxies are indistinguishable from bright dE profiles. In 2D, the dS0s appear highly flattened and/or show asymmetric and irregular features which may indicate their disk nature.
