Retinoic Acid Embryopathy

Area of Science:

• Teratology and developmental toxicology
• Clinical teratology
• Pharmacology of retinoids

Background:

• Isotretinoin, a Vitamin A derivative, treats severe cystic acne.
• It is a known teratogen, causing significant birth defects.
• Previous studies link prenatal isotretinoin exposure to malformations.

Observation:

• A newborn presented with multiple congenital anomalies.
• The infant had a history of prenatal exposure to isotretinoin.
• Observed defects included anotia, microtia, congenital heart disease, and CNS malformations.

Findings:

• Detailed case report of a neonate with isotretinoin embryopathy.
• Specific craniofacial defects: left anotia, right microtia.
• Associated complex congenital heart disease and central nervous system malformation.

Implications:

• Reinforces the teratogenic risks of isotretinoin.
• Highlights the need for strict prescribing guidelines and patient counseling.
• Informs clinical management and genetic counseling for exposed pregnancies.
