Abstract	dc.description.abstract	We prove, via a pathwise analysis, an existence result for stochastic differential equations with singular coefficients that govern stochastic vortex systems. The techniques are self-contained and rely on careful estimates on the displacements of particles, obtained by recursively identifying "vortex clusters" whose mutual interactions can be controlled. This provides a non trivial extension of techniques of Marchioro and Pulvirenti((7)) for deterministic motion of vortices.	es_CL
