Severe semilobar holoprosencephaly and lissencephaly associated with cebocephaly in a newborn: Holoprosencephaly is frequently accompanied by midline facial abnormalities such as hypotelorism, cyclopia, etmocephaly and cebocephaly. Cebocephaly is a very rare congenital anomaly combining with semilobar holoprosencephaly. Chromosomal analysis shows normal karyotyping. Lissencephaly and holoprosencephaly are rare associations, that have not been reported yet with cebocephaly. Herein we present the first case of cebocephaly with severe semilobar holoprosencephaly and lissencephaly.
