  We consider high order current cumulants in disordered systems out of
equilibrium. They are interesting and reveal information which is not easily
exposed by the traditional shot noise. Despite the fact that the dynamics of
the electrons is classical, the standard kinetic theory of fluctuations needs
to be modified to account for those cumulants. We perform a quantum-mechanical
calculation using the Keldysh technique and analyze its relation to the quasi
classical Boltzmann-Langevin scheme. We also consider the effect of inelastic
scattering. Strong electron-phonon scattering renders the current fluctuations
Gaussian, completely suppressing the $n>2$ cumulants. Under strong
electron-electron scattering the current fluctuations remain non-Gaussian.
