We investigated linear and nonlinear properties of electromagnetic ion-temperature-gradient driven mode for a dissipative, nonuniform dust-contaminated electron-ion plasma with sheared ion flows. In the linear limit, a new dispersion relation has been derived and several interesting limiting cases are also discussed. On the other hand, in the nonlinear case, by ignoring dissipative effects, the nonlinear set of equations admits a dipolar vortex type solution. The results of the present investigation should be helpful to understand some linear as well as nonlinear properties of magnetically confined dust-contaminated tokamak edge plasmas.
