Spatially resolved properties for extremely metal-poor star-forming
  galaxies with Wolf-Rayet features and high-ionization lines
  Extremely metal-poor, high-ionizing starbursts in the local Universe provide
unique laboratories for exploring in detail the physics of high-redshift
systems. Also, their ongoing star-formation and haphazard morphology make them
outstanding proxies for primordial galaxies. Using integral field spectroscopy,
we spatially resolved the ISM properties and massive stars of two first-class
low metallicity galaxies with Wolf-Rayet features and nebular HeII emission:
Mrk178 and IZw18. In this review, we summarize our main results for these two
objects.
