  We consider a nonlinear parabolic problem with dynamical boundary conditions
in a media perforated by periodically distributed holes of size $\varepsilon$.
The existence and uniqueness of solution is analyzed. Moreover, passing to the
limit when $\varepsilon$ goes to zero, a new nonlinear parabolic problem
defined on a unified domain without holes with zero Dirichlet boundary
condition and with extra-terms coming from the influence of the dynamical
boundary conditions is rigorously derived.
