Abstract: We show that, in any Banach space, the sum of an $ m$-accretive operator and of a continuous accretive operator is $ m$-accretive; that achieves a slight generalization of such theorems which are already known, but the method used here is very different and also comes to a new result about (nonnecessarily accretive) locally Lipschitz continuous perturbations of $ m$-accretive operators. The case when the perturbation depends on time is also considered.
