We analyze the anomalies of superconducting state in the model of pseudogap state induced by fluctuations of short - range order of "dielectric" (AFM(SDW) or CDW) type, and based on the scenario of "hot spots" formation on the Fermi surface, with the account of all Feynman graphs for electron interaction with pseudogap fluctuations, leading to strong scattering around the "hot spots". We determine the dependence of superconducting critical temperature Tc on the effective width of the pseudogap, correlation length of short - range order and concentration of nonmagnetic impurities. We also discuss possible connection of these results with the general form of the phase diagram of superconducting cuprates.
