Synopsis

Aplasia cutis congenita is a congenital disorder seen in newborns. It typically manifests as an absence of the skin of the scalp but can occur in any location. While most children have no other associated abnormalities, cleft lip and palate, tracheoesophageal fistula, double cervix and uterus, patent ductus arteriosus, coarctation of the aorta, cutis marmorata telangiectatica congenita, arteriovenous (AV) fistulas, central nervous system (CNS) dysraphisms, and intestinal lymphangiectasia have been reported with the anomaly. The newborn can present with an open erosion or a healed, depressed scar.

For more information, see OMIM.

Differential Diagnosis & Pitfalls

Many cases of aplasia cutis congenita do not have other associated findings. However, the lesion has been associated with trisomy 13, which should be considered if other signs and symptoms of trisomy 13 are present.

Aplasia cutis congenita is also seen in focal dermal hypoplasia (Goltz syndrome), epidermolysis bullosa simplex, and defects in other genes affecting several other morphogenic pathways.
