  We study the equation --div(A(x, u)) = g(x, u, u) + $\mu$ where $\mu$ is a
measure and either g(x, u, u) $\sim$ |u| q 1 u||u| q 2 or g(x, u, u) $\sim$ |u|
s 1 u + ||u| s 2. We give sufficient conditions for existence of solutions
expressed in terms of the Wolff potential or the Riesz potentials of the
measure. Finally we connect the potential estimates on the measure with
Lipchitz estimates with respect to some Bessel or Riesz capacity.
