 In both the source novel and this film, the Scaramanga character has  an additional nipple which in reality can be a real biological  occurrence. It is known as a supernumerary nipple but can also be  called an accessory nipple or third nipple. The medical name for  such can be either polythelia or polymastia. In this movie though,  it is referred to as a superfluous papilla. In the James Bond parody  movie _Austin Powers in Goldmember (2002)_ (qv), the Goldmember  character also has a third nipple.
