Introduction: Bartsocas-Papas syndrome (BPS) is a lethal condition caused by a homozygous mutation of the RIPK4 gene, which, being part of a complex molecular network, is involved in keratinocyte differentiation while. The main clinical manifestations are webbing of lower limbs, facial clefts, distal limb reduction defects, and skin tags, and some of these are shared with other monogenic ectodermal dysplasia syndromes. Similarly, amniotic bands sequence (ABS), a condition of unknown etiopathogenesis, is characterized by a variable spectrum of anomalies considered as disruptive, such as facial clefts and limb reduction defects. Objective: to describe clinical and autopsy findings of a patient with BPS and of a fetus with ABS, emphasizing on their similarities. Case reports: 1. Female liveborn with atypical facial clefts, popliteal and crural webbing, distal reduction defects of hands and feet, and multiple skin tags. The placenta showed regions lacking amniotic epithelium. 2. Female fetus of 27 gestational weeks, atypical facial clefts, distal limb reduction defects, popliteal webbing, thoracoabdominal and cephalic closure defects, skin tags, and amniotic bands. Placenta and umbilical cord showed broad regions lacking amniotic epithelium attachment. Conclusions: the observation of a number of findings with remarkable similarities between BPS and ABS allows   considering   the existence of an intrinsic factor, involved in skin development which is common to both conditions.
