Latest results on tetra- and penta-quark candidates from LHCb

Thanks to its unique capabilities the LHCb experiment has been making important contributions to the spectroscopy of exotic hadrons; among them the X(3872), Z(4430)$^{\mathrm{+}}$ tetraquark and the P$_{\mathrm{c}}$(4380)$^{\mathrm{+}}$, P$_{\mathrm{c}}$(4450)$^{\mathrm{+}}$ pentaquark candidates. The latest results on tetraquark and pentaquark candidates will be presented.
