Human choriogonadotropin (hCG) is a glycoprotein hormone normally produced by the trophoblastic tissue of the placenta. However, it has also been reported that nontrophoblastic malignant tumors (Rabson et al., 1973; Vaitukaitis et al., 1976) and normal human tissues (Yoshimoto et al., 1977) may produce hCG or an hCG-like substance. All these descriptions of extra placental production of hCG deal with tissues of mammalian origin.
