Yukio Matsumoto in "A 4-manifold which admits no spine", see <a href="https://projecteuclid.org/euclid.bams/1183536434">here</a>, constructed a compact PL $4$-manifold with boundary that is homotopy equivalent to the $2$-torus but does not deformation retract to a PL-embedded copy of $T^2$. There are also examples of this phenomenon in higher even dimensions by Cappell and Shaneson, see <a href="http://www.maths.ed.ac.uk/~aar/papers/capsha6.pdf">here</a>. I do not know whether these manifolds admit topological (i.e. non PL) spines.
