Abstract

Oculoauriculovertebral spectrum or Goldenhar syndrome is a phenotypically and probably genetically heterogeneous disorder characterized by hemifacial microsomia (unilateral ear abnormalities and ipsilateral mandibular hypoplasia) as well as vertebral anomalies and epibulbar dermoid/lipodermoids. Although most cases of the Goldenhar syndrome are sporadic, both autosomal recessive and dominant inheritance have been reported so far. In this report, we describe the clinical aspects of two familial cases with evidence of autosomal dominant inheritance and a non-familial case, and compare them with the reports in the literature. One of our familial cases was a ten day old female infant of a mother with left hemifacial microsomia. She had multiple bilateral preauricular tags and a "fleshy masse" on her right cheek. The other familial case was a two months old male infant whose father had hemifacial asymmetry. He had unilateral microtia, and abnormal antihelix, a skin tag in the contralateral ear associated with bilateral sensorineural hearing loss. The third case was a sporadic case who was 2 years old boy with preauricular skin tag, right hemifacial microsomia and limbal dermoid at the temporal limbus of the right eye. As there were no other associated defects, the cases we presented here were thought to be mild variations of the Goldenhar spectrum. The most commonly encountered mutations of thrombophilia genes were studied. We believe that the interfamilial and intrafamilial clinical variabilities observed in these cases reinforce the necessity of a careful examination for the whole family with regards to the stigmata of Goldenhar syndrome.
