    Area of Science:

    • Medical Genetics
    • Developmental Biology
    • Teratology

    Background:

    • Anterior craniofacial duplication, termed diprosopus, is an exceptionally rare congenital anomaly.
    • It is characterized by duplication of facial features on a single fetal trunk.

    Observation:

    • A series of three infants with diprosopus was reported from Southern California.
    • Each infant presented with two distinct faces, including four eyes, two noses, two mouths, and two ears.
    • Associated internal organ aberrations were also noted.

    Findings:

    • This series represents the largest reported collection of diprosopus cases to date.
    • The infants exhibited significant craniofacial duplication and multiple congenital anomalies.
    • Pathogenesis remains unclear, with theories suggesting early embryologic environmental stress and slowed pregastrulation oxidation leading to developmental arrests.

    Implications:

    • This case series expands the understanding of diprosopus, a condition with limited documented instances.
    • Further research into the environmental and developmental factors is crucial for understanding and potentially preventing such profound malformations.
    • Highlights the need for comprehensive evaluation of infants with rare congenital anomalies.
