Three-generation family with resemblance to Townes-Brocks syndrome and Goldenhar/oculoauriculovertebral spectrum.

The Townes-Brocks syndrome (TBS) is comprised of a triad including characteristic anal, thumb, and ear anomalies. There are many other organ system abnormalities which may be present. However, the literature does not emphasize craniofacial findings except with reference to the typical ear configuration. A three-generation family is described in which craniofacial manifestations were prominent and a Goldenhar-like condition was considered as the most likely diagnosis. However, with the recent birth of an affected male who had an imperforate anus, the diagnosis of TBS was also considered. The family manifests a variety of Goldenhar-like findings, including epibulbar dermoids, hemifacial microsomia, preauricular tags, macrostomia, and micrognathia in addition to classical ear, radial, and anal findings of TBS. We report on this family to point out a possible biological relationship of these two conditions.
