title: A rare case of cytogenetic discrepancy between extraembryonic and fetal tissue.
abstract: We present a case of false-negative discrepancy between extraembryonic and fetal tissue sampled at 14 weeks of amenorrhoea when ultrasound examination showed morphological anomalies of the fetus. The same cytogenetic characteristic was confirmed on tissue samples after abortion.
