We prove the existence of a unique mild solution for a stochastic evol
ution equation on a Hilbert space driven by a cylindrical Wiener proce
ss. The generator of the corresponding evolution system is supposed to
be random and adapted to the filtration generated by the Wiener proce
ss. The proof is based on a maximal inequality for the Skorohod integr
al deduced from the Ito's formula for this anticipating stochastic int
egral.
