The structure of hyperons is studied within the context of the bound state soliton model. In this approach strange hyperons are described as bound states of an SU(2) topological soliton and kaons. Masses and electromagnetic properties of the strange baryons are calculated in a version of the model where chiral symmetry breaking effects due to the different empirical values of the pion and kaon decay constants are considered. The possibility of extending this scheme to the description of other massive-quark baryons like charmed hyperons is also discussed.
