Query: On the pentaquark candidates $P_c^+(4380)$ and $P_c^+(4450)$ within the
  soliton picture of baryons   Using the bound state version of the topological soliton model for the
baryons we show that the existence of a bound (or quasi-bound) $\bar D$-soliton
state leads to the possibility of having hidden charm pentaquarks with quantum
numbers and masses, which are compatible with those of the candidates recently
reported by the LHCb experiment. The implications of heavy quark symmetry are
elaborated.
