Port-wine stains (PWS) are capillary malformations associated with mutation in the GNAQ (NM_000441.1) gene. Large vestibular aqueduct syndrome (LVAS), caused by mutation in the SLC26A4 (NM_002072) gene, is an inner ear malformation that can lead to hearing loss. To our knowledge, LVAS in PWS patients has never been reported. Here, we describe a case of a 9-year-old female patient diagnosed with PWS on the face and neck, coexisting with large vestibular aqueduct syndrome. Further analyses revealed a somatic mutation in GNAQ and a compound heterozygous mutation in the SLC26A4 gene. Some PWS patients have associated abnormalities, such as glaucoma and choroidal hemangioma, leptomeningeal angiomas and atrophy or hypertrophy of bone and soft tissue. We present here the first case that reveals the possibility that capillary malformations are associated with inner ear malformation. More case reports and further studies are needed to determine whether these conditions coexist in other patients.
