The cytologic appearance is described of hemangioendothelioma in fine needle aspiration smears from a young male who presented with recurring bilateral lesions within two years. The cytomorphologic pattern was extremely cellular, with a monomorphic population of cells, some of which showed a tendency to form rosettelike or pseudoacinar formations.
