We show that, in the 3-3-1 model with right-handed neutrinos, small neutrino masses and large lepton flavor violating processes such as {mu}{yields}3e and {mu}{yields}e{gamma} can be obtained by just introducing an additional Higgs sextet. In the limit of vanishing of the Yukawa interaction among Higgs and lepton triplets (h{sup {nu}}=0), the decay {mu}{yields}3e strongly depends on the neutrino-mass patterns, but the {mu}{yields}e{gamma} almost does not. The neutrino masses are not constrained by such processes in the cases of h{sup {nu}}{ne}0.
