We use QCD sum rules to study the possible existence of a \Theta c(3250)charmed pentaquark. We consider the contributions of condensates up todimension-10 and work at leading order in \alpha_s. We obtain m(\Theta c) =(3.21 +/- 0.13) GeV, compatible with the mass of the structure seen by BaBarCollaboration in the decay channel B- -> p- \Sigma c++ pi- pi-. The proposedstate is compatible with a previous proposed pentaquark state in theanti-charmed sector.
