A peculiar compact H II region was discovered in the Large Magellanic Cloud (LMC). The nebula, N82, has chemical abundance anomalies; nitrogen is enriched with respect to the average LMC value by a factor of 5, whereas oxygen is depleted by a factor 2.5. This very compact H II region seems to have been ejected by the central late type Wolf-Rayet star of the carbon sequence, the only WC 9 star known in the LMC. There is at least one additional massive star of estimated type 08 V within the H II region as indicated by the presence of He II absorption lines in the nebular spectrum.
