Three cases of ring nebulae around a WC6 star are definitely known : one is around HD 92809 north of the Carina Nebula (Lortet et al. 1980), another around θ Mus has been studied by Heckathorn et al (1982). We here study the third one, NGC 6357 around HD 157504, first quoted in the survey by Heckathorn et al (1981 and 1982).
