  V578 Mon is an eclipsing binary system in which both stars have masses above
10 Msun determined with an accuracy better than 3%. It is one of only five such
massive eclipsing binaries known that also possess eccentric orbits and
measured apsidal motions, thus making it an important benchmark for theoretical
stellar evolution models. However, recently reported determinations of the
radii of V578 Mon differ significantly from previously reported values. We
reanalyze the published data for V578 Mon and trace the discrepancy to the use
of an incorrect formulation for the stellar potentials in the most recent
analysis. Here we report corrected radii for this important benchmark eclipsing
binary.
