We report on a class of dark solitons and vortices existing in the exciton-polariton condensates and having discontinuity in their excitonic component. These solutions exist due to an intrinsic bistability of the exciton density in the given optical field and for nonzero detuning between the cavity and excitonic resonances. We specify a well defined energy boundary where they transform into previously known polaritonic dark solitons and vortices.
