title: Frontonasal dysgenesis, first branchial arch anomalies, and pericallosal lipoma: A new subtype of frontonasal dysgenesis.
abstract: We report on two unrelated Brazilian boys with craniofacial anomalies that involve the frontonasal process and the first branchial arch associated with pericallosal lipoma. To our knowledge this condition seems to have been reported only once previously, but may represent a new condition within the group of the frontonasal dysgenesis. Clinical and imaging data, phenotypic evolution, and differential diagnosis are discussed.
