  We present Spitzer Space Telescope images of the isolated dwarf galaxy UGC
10445. The galaxy is detected at all photometric bands (3.6-160um) as well as
in the Multiband Imaging Photometer for Spitzer (MIPS) spectral energy
distribution mode (55-95um). We derive a star formation rate of 0.25 M_sun/yr
based on H-alpha and infrared flux densities. There is over 10^6 solar masses
of cold dust (T~18K) in the galaxy, represented by 160um emission, that extends
to a larger radius than the ultraviolet (UV), optical and near-infrared light.
Such extended emission has been seen previously only in dwarf galaxies in
cluster environments. We suggest the source of heating for this dust is UV
light originating in star forming complexes. To produce the large quantity of
dust requires a higher rate of star formation in the past than is observed
currently.
