  The generating functional of heavy baryon chiral perturbation theory at order
O(Q^2) in the mean field approximation (with a pseudoscalar source coupling
which is consistent with the PCAC-Ward identities on the current quark level)
has been exploited to derive Migdal's in--medium pion propagator. It is shown
that the prediction for the density dependence of the quark condensate obtained
on the composite hadron level by embedding PCAC within the framework of
Migdal's approach to finite Fermi systems is identical to that resulting from
QCD.
