Static spherically symmetric perfect fluid solutions are studied in metric f(R) theories of gravity. We show that pressure and density do not uniquely determine f(R) i.e. given a matter distribution and an equation state, one cannot determine the functional form of f(R). However, we also show that matching the outside Schwarzschild-de Sitter metric to the metric inside the mass distribution leads to additional constraints that severely limit the allowed fluid configurations.
