A man's penis rotted after he injected it with petroleum jelly to try and make his member bigger, doctors have revealed.
The unnamed man, from the South Pacific islands, visited A&E feeling unwell and suffering from itchiness on his penis for five days.
He recalled injecting himself with petroleum jelly - the main ingredient in Vaseline - two years ago after his doctors quizzed him on his sexual behaviour.
The penile shaft was 'grossly deformed' due to gangrene, with rotting flesh and a build-up of pus.
The man was rushed into emergency surgery, and endured two more operations to save the remains of his genitals.
He recalled treating an 'unwell looking man', who was feeling weak and suffering fevers when he sought help.
Upon examination, doctors found his penis was tender, had a severe build-up of fluids, and patches of visible rotting flesh.
He was diagnosed with Fournier's gangrene, a life-threatening and rapidly progressing 'flesh-eating bug' of the genitals.
Surgeons removed the rotting tissue and drained the pus-filled pockets in emergency surgery.
They also found 'a large amount of petroleum jelly' in the penile shaft - although the man denies using it since the first encounter two years ago.
At A&E, doctors found the unnamed man's penis was 'grossly deformed' due to gangrene. The man, from South Pacific islands, injected petroleum jelly two years previously.
