I will talk about our research work on two B[e] supergiants in the Magellanic Clouds: LHA 115-S 18 and LHA 120-S 35. Based on high-resolution optical spectra, we have discovered the appearance of Raman-scattered lines in LHA 115-S 18. This is the first time that these lines have been detected in the spectrum of a massive luminous B[e] star. Concerning to LHA 120-S 35, we will present a spectroscopic study based on high-resolution optical and medium resolution K-band near infrared spectra. The main result is the first detection of CO band emission in this peculiar star.
