  The scalar ``cosmon'' field mediating quintessence influences the dynamics of
extended objects in the universe. We discuss cosmon lumps -- spherically
symmetric solutions for the scalar field coupled to gravity. The two
integration constants can be associated to the mass and the rotational velocity
in a halo-like region with constant rotation curve. The presence of the scalar
field also changes the singularity of the black hole solution. We ask if
galaxies could be associated with cosmon lumps.
