Severe oculocerebrocutaneous (Delleman) syndrome: overlap with Goldenhar anomaly.

Oculocerebrocutaneous syndrome (OCCS), or Delleman syndrome, is a multiple congenital anomaly syndrome characterized by orbital cysts, cerebral malformations, and focal dermal hypoplasia [Delleman and Oorthuys, 1981, Clin Genet 19:191-198; Delleman et al., 1984, Clin Genet 25:470-472]. Two previous reports presented children having what is suggested as the more severe form of the OCCS syndrome who also had anophthalmia, congenital hydrocephalus, and cleft lip and palate [Leichtman et al., 1994, Am J Med Genet 50:39-41; Angle and Hersh, 1997, Am J Med Genet 68:39-42]. We report on a third case of severe OCCS, an infant girl with a similar constellation of findings and additional anomalies including lateral facial cleft, vertebral anomaly, and ventricular septal defect. The additional findings in our patient highlight the phenotypic overlap of OCCS and the Goldenhar anomaly, an overlap previously noted by Delleman and Oorthuys [1981], and others [Al-Gazali et al., 1988, J Med Genet 25: 773-778]. We suggest that the minimal diagnostic criteria for Delleman syndrome include central nervous system cyst or hydrocephalus, orbital cysts or microphthalmia, and focal skin defects.
