His name is Durga, clan Besaidii (Jabba is clan Desilijic, they aren't related), and it's a birthmark. Birthmarks are bad luck amonst the Hutts, which is why many within his clan did not want him to rule when his father, Aruk? died. He took command anyway, after slaying his fathers executioner, Jiliac,(Jabba's uncle/aunt) in a Hutt duel, which allowed Jabba to take control of clan Desilijic.
Unfortunately, the bad-luck superstition about the birthmark proved to be true; Durga eventually had to become a vassal of Black Sun, and bankrupted his clan with the Darksaber project, which brought about his own untimely destruction.
