Is there a name for this? other than being a crazed lunatic?

is there an actual medical term for a person who often pretends to be sick or dying, and they know nothing is wrong with them but they just act like they are majorly ill or about to die in order to get attention and sympathy? I know someone who does this often and it has been years and not once has he ever actually been hurt or ill or gone to the doctor/ER. Its all just made up bullshit to try and get me to give him sympathy. its different from hypochondria because i know he knows full well that nothing is wrong.
