Partial cubes have been extensively investigated as well as planar graphs. In this note we introduce an additional topological kind of condition to the Chepoi's expansion procedure that characterizes planar partial cubes. As a consequence we obtain a characterization of some other planar subclasses of partial cubes.
For a characterization of planar partial cubes see Peterin REF .
