Tattoos are a prominent part of the story,
The english title of the first book is The girl with the Dragon tattoo
In the First book: Lisbeth is desribed as having a wasp tattoo about an inch long on her neck, a tattooed loop around the biceps of her left arm and another around her left ankle. On those occasions when she had been wearing a tank top, a dragon tattoo can be seen on her left shoulder blade.
In The girl who played with fire she has had the wasp removed. But in the movie it can be seen sometimes.
The movies add and enlarge the tattoo's.
In The Girl with the Dragon tattoo Lisbeth tattoo's Nils Bjurman with the words "I AM A SADISTIC PIG, A PERVERT, AND A RAPIST" on his abdomen
