Significant ophthalmoarthropathy associated with ectodermal dysplasia in a child with Marshall-Stickler overlap: a case report

摘要

Background The Marshall-Stickler phenotype is an autosomal dominant trait comprising ocular abnormalities, sensorineural hearing loss, craniofacial anomalies, and anhidrotic ectodermal dysplasia. Case presentation A 5-year-old boy from non-consanguineous family in Austria was born with features of Pierre-Robin association (cleft palate, micrognathia, and glossoptosis). Radiological examination at birth revealed coronal clefts of the vertebrae, platyspondyly, and flaring of the metaphyses of the long bones (features suggestive of the Weissenbacher-Zweymuller syndrome). Significant features of ectodermal dysplasia such as sparse hair, defective dentition, dysplastic nails, and deficient sweating associated with bouts of unexplained hyperthermia were present. These features not shared by Stickler syndrome, Wagner syndrome, or Weissenbacher – Zweymuller syndrome, all of which are conditions often confused with Marshall syndrome. Conclusion There is continuing debate over the clinical overlap and differential diagnosis of Marshall and Stickler syndromes. We compared similar disorders, such as Weissenbacher-Zweymuller, and Wagner syndromes, and conclude that our present patient manifests Marshall-Stickler overlap. Focussing on subtle facial and ectodermal features may detract from recognising the serious outcome of congenital vitreous/myopia anomaly. Retinal detachment with subsequent blindness is a major risk in our current patient.
