  In this paper we study germs of holomorphic foliations, at the origin of the
complex plane, tangent to Pfaffian hypersurfaces - integral hypersurfaces of
real analytic 1-forms - satisfying the Rolle-Khovanskii condition. This
hypothesis leads us to conclude that such a foliation is defined by a closed
meromorphic 1-form, also allowing the classification of the simple models in
its reduction of singularities.
