  We review the quark-mass dependence of the baryon octet and decuplet masses
as obtained from recent lattice simulations of the BMW, PACS-CS, LHPC, HSC and
QCDSF-UKQCD groups. Our discussion relies on the relativistic chiral Lagrangian
and large-$N_c$ sum rule estimates of the counter terms relevant for the baryon
masses at N$^3$LO. A partial summation is implied by the use of physical baryon
and meson masses in the one-loop contributions to the baryon self energies. In
our analysis the physical masses are reproduced exactly by means of a suitable
set of linear constraints. A quantitative and simultaneous description of all
lattice results is achieved in terms of a six parameter fit, where the symmetry
conserving counter term that are relevant at N$^3$LO are not yet being used.
For pion masses larger than 300 MeV there appears to be an approximate linear
pion-mass dependence of all octet and decuplet baryon masses. We discuss the
pion- and strangeness sigma terms of the baryon octet states.
