We study the local properties of positive solutions of the equation -Δu=up-m|∇ u|q in a punctured domain Ω∖\0\ of ℝN or in a exterior domain ℝN∖ Br0 in the range min\p,q\>1 and m>0. We prove a series of a priori estimates depending p and q, and of the sign of q-\frac 2pp+1 and q-p. Using various techniques we obtain removability results for singular sets and we give a precise description of behaviour of solutions near an isolated singularity or at infinity in ℝN.
