Fetus in fetu
Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of a true fetus. An early example of the phenomenon was described in 1808 by George William Young. There are two hypotheses for the origin of a fetus in fetu. One hypothesis is that the mass begins as a normal fetus but becomes enveloped inside its twin. The other hypothesis is that the mass is a highly developed teratoma. Fetus in fetu is estimated to occur in 1 in 500,000 live births (0.0002%).
