I would first check the outlets wiring using a simple tester like this one AC Outlet Tester or AC Outlet Tester with LCD

You MacBook Pro case can get power leakage via the outlet if the outlet is mis-wired or you have a leaking device so the ground leg is becoming hot. Your MacBook's logic is strictly DC so its not something within its circuitry.

While its possible something within the charger has failed or within your power cord to make the MacBook case hot its quite rare!
