  We report on XMM-Newton observations of G32.45+0.1 and G38.55+0.0. These were
discovered as diffuse hard X-ray sources with the ASCA Galactic plane survey,
but the limited spatial resolution of ASCA could not conclude whether these are
truly diffuse or a group of unresolved point-sources. XMM-Newton, with higher
spatial resolution than ASCA, confirmed that G32.45+0.1 has a diffuse
shell-like structure with a radius of ~4'. The spectrum shows featureless
continuum, hence can be fitted with a power-law model of Gamma ~2.2 with an
absorption of N_H~5.2*10^{22}cm^{-2}. From this N_H value, we estimate the
distance to G32.45+0.1 to be ~17kpc, then the luminosity (in the 0.5-10.0keV
band) and radius of the shell are ~9.5*10^{34}ergs/s and ~20pc, respectively.
The radio complex sources in the NRAO/VLA Sky Survey (NVSS; 1.4GHz) are
globally associated to the X-ray shell of G32.45+0.1. Therefore G32.45+0.1 is
likely to be a synchrotron dominant shell-like SNR. No significant diffuse
structure was found in the XMM-Newton image of another ASCA diffuse source
G38.55+0.0. The upper limit of the observed flux (0.5-10.0keV) is estimated to
be 9.0*10^{-13}ergs/cm^2/s being consistent with the ASCA result.
