We investigate spherically symmetric spacetimes which contain a perfect fluid obeying the polytropic equation of state and admit a kinematic self-similar vector of the second kind which is neither parallel nor orthogonal to the fluid flow. We assume two kinds of polytropic equations of state and show in general relativity that such spacetimes must be a vacuum, which is in contrast with the result in the Newtonian case.
