Gavin Hyatt, 30, explained that the lump forced its way out after lying inside his abdomen since he was born.
Medics said the 4cm growth was a parasitic twin that died in the womb early in their mother's pregnancy.
Mr Hyatt, a former firefighter, from Witney, Oxfordshire, said: "Four hospital doctors had previously examined me and were all puzzled by the lump.
"Some thought it was a cyst, others an in-grown hair.
"Then one said it could be my undeveloped identical twin that I absorbed at a very early stage. I feel absolutely fine now but it has not sunk in yet that I could have had a twin brother. I have him in a jar at home and I call him little Gav. I haven't told many people. I feel like a bit of a freak."
Mr Hyatt, who has four children with his wife Kate, spent a week in and out of hospital after making an emergency appointment with the GP.
An operation at Oxford's John Radcliffe Hospital was cancelled at the last minute and he went home. But later he felt a stabbing pain near his belly button. Lifting his shirt, he saw he was bleeding as the lump pushed through the skin. At that point he drove himself to his local surgery.
His GP Dr Joe Santos, told The Sun: "It was like something from Alien. I didn't believe Gavin when he said something was coming out of his belly button until I saw him."
Um, I think if I kept my twin that purged itself from my body I probably wouldn't keep it in a jar on a shelf. Or maybe I would and get it a little tophat and cane. Or I'd bury my mini-freak and have a little rite of some sort. Either way, this guy definitely qualifies as a freak. Sorry dude. He is. This doesn't happen to normal people.
Really thinking about it, the twin travelled for 30 freaking years to reach the surface! That is a boring life. I wonder if it felt all the emotions of the guy. Lived the man's life with him. Loved the same loves. There to pick him up when he fell down.
I'm getting carried away.
