The narrow-line Seyfert 1 galaxy IRAS 07598+6508 is known to be a stong Fe II emitter. The analysis of several high S/N ratio spectra shows that its spectrum is dominated by a relatively narrow broad line region (1780 km s(-1) FWHM) emitting not only Fe II, but also Ti II and Cr II lines. Although we were unable to find a completely satisfactory physical model, we got the best agreement with the observations with collisional rather than radiative models, with a high density (n = 10(15) cm(-3)), a high column density (N-H = 10(25) cm(-2)) and a microturbulence of 100 km s(-1). This BLR is qualitatively similar to the one observed in IZw1. We have not found traces in IRAS 07598 + 6508 of the narrow line regions found in IZw1.
