RESUMEN
Capillary malformation-arteriovenous malformation is a rare autosomal dominant disorder associated with EPHB4 loss-of-function mutations. We report the unique presentation of a 6-year-old girl with multiple capillary malformations in a unilateral segmental distribution affecting the right hemiface, right upper chest, and right arm associated with overgrowth. Targeted next-generation sequencing on a tissue sample revealed a novel heterozygotic variant in the EPHB4 gene (NM_004444.5 (EPHB4): c.715T>A, p.[Cys239Ser]). This case highlights a distinct presentation of CM-AVM type 2 and showcases a new variant in EPHB4 not previously reported in the literature.
