We present results for the light, strange and charm quark masses using
$N_f=2+1+1$ twisted mass fermion ensembles at three values of the lattice
spacing, including two ensembles simulated with the physical value of the pion
mass. The analysis is done both in the meson and baryon sectors. The difference
in the mean values found in the two sectors is included as part of the
systematic error. The presentation is based on the work of Ref. [1], where more
details can be found.
