Background: Holoprosencephaly is a rare and possibly fatal neural tube defect represented by complete or partial forebrain noncleavage. It can be classified into four types: alobar, semilobar, lobar, and middle interhemispheric fusion variant. It is usually diagnosed through prenatal ultrasound or after birth by visually observing the morphological abnormalities and/or through neurological screening. Potential causes include maternal diabetes, alcoholism, infections during pregnancy, drugs, and genetic causes. Case presentation: Herein, we report two cases of holoprosencephaly’s rarest manifestations, albeit cebocephaly in the first case, and cyclopia with a probocis in the second. Cebocephaly, (hypotelorism with a single nostril and a blind-ended nose) was present in the first case; a Syrian newborn girl for a 41-year-old mother who works in collecting Capparis spinosa, and cyclopia with skull vault absence and posterior encephalocele in the second case; a Syrian newborn girl for a 26-year-old mother, the parents here where second-degree relatives. Conclusions: Early diagnosis through ultrasound is preferred in such cases and management options should be assessed and discussed with the parents due to poor prognosis. Adherence to pregnancy follow-up programs is essential to detect malformations and disorders as early as possible, especially when risk factors exist. Also, this paper may suggest a potential correlation between C. spinosa and holoprosencephaly. Therefore, we suggest that more research should be done.
