Vascular Stains and Hair Collar Sign Associated with Congenital Anomalies of the Scalp

Abstract

We reported a series of three meningothelial hamartomas, one benign fibrous tumor, and one aplasia cutis congenita presenting with the hair collar sign and a coexistent vascular stain. Our series highlighted the importance of coexisting cutaneous markers found in the newborn period. The presence of a vascular stain and hair collar sign with or without a congenital scalp nodule should increase suspicion of an associated cranial dysraphism.
