According to a new case report, a teenager in India had a bizarre mass of bones, teeth and "hairy cheese" in his stomach. It was her own "twin" that grew in her, the result of an extremely rare disease called " fetus in the fetus ".
The 17-year-old went to the doctor after having a lump in her stomach over the past five years, which had gradually increased. This emerges from the report, which was published on August 12 in the journal BMJ Case Reports . The teenager told the doctors that sometimes she had stomach aches and a sense of fullness, even though she had not eaten much.
A CT scan revealed that the teenager had a large mass in her stomach that appeared to contain multiple bones that "resembled the shape of vertebrae, ribs and long bones," the authors wrote.
Doctors diagnosed in the adolescent fetus of the fetus, a condition that is estimated to occur only in about 1

The New Case is even more uncommon since it was diagnosed in teenagers, while most previous cases in childhood or adolescence have occurred early childhood, the authors said, in addition, the mass seems to be the largest ever discovered in such a case
The term "fetus in the fetus," which literally means "fetus inside" means "fetus" is commonly defined as a condition in which a developmentally abnormal fetus is present in the body of its otherwise healthy twin is found. Live Science previously reported .
There are fewer than 200 cases of fetus found in the fetus Medical literature reports that only seven individuals were aged 15 years or older, according to the authors. However, scientists consider the disease to be a rare case of " parasitic twins ", in which an identical twin is absorbed by the other during early pregnancy, according to the Arizona State University . The tissue of the parasitic twin depends on the body system of the "host" twin to survive, as revealed by a review on parasitic twins from 2010 published in the Journal of Pediatric Surgery (19459004). Researchers believe that the fetus is present in the fetus is actually a type teratoma – a type of tumor that may contain all three major cell types of a human embryo at an early stage.
In this case, the teenager had to undergo surgery to remove the mass. When the doctors took it out, the mass was about two-thirds the size of a full-time baby: it measured 36 by 16 by 10 centimeters and consisted of hairy, cheesy material, several teeth and structures reminiscent of buds, "the authors wrote They also contained skin, hair, and adipose tissue, they said.
However, physicians were unable to remove all parasitic twin tissue from the teenager's body – they had to leave some of this tissue behind because it was too tight attached to blood vessels supplying the gastrointestinal tract The physicians feared that removal of the adherent tissue might affect the circulation of the juvenile intestine.
However, if this tissue is admitted, it is possible to Therefore, the juvenile tissue needs to be examined every year, authors said, so far two years have passed since the teenage years has been operated and is doing well, the report said. "I feel very well after the operation … and my parents are very happy too."
