Abstract
We describe ISO observations of the obscured Asymptotic Giant Branch (AGB) star IRAS04496-6958 in the Large Magellanic Cloud (LMC). This star has been classified as a carbon star. Our new ISOCAM CVF spectra show that it is th e first carbon star with silicate dust known outside of the Milky Way. The existence of this object, and the fact that it is one of the highest lumino sity AGB stars in the LMC, provide important information for theoretical mo dels of AGB evolution and understanding the origin of silicate carbon stars .
