Cantú syndrome: report of nine new cases and expansion of the clinical phenotype.
Cantú syndrome, a rare disorder of congenital hypertrichosis, characteristic facial anomalies, cardiomegaly, and osteochondrodysplasia was first described in 1982 by Cantú. Twenty-three cases of Cantú syndrome have been reported to date. The pathogenesis of this rare autosomal dominant condition is unknown. We describe 10 patients with Cantú syndrome (9 new cases and the long-term follow-up of a 10th case reported by Robertson in 1999) comparing the phenotype with that of the previously reported cases. We describe how the distinctive facial appearance evolves with time and report several new findings including recurrent infections with low immunoglobulin levels and gastric bleeding in some of our patients. The cardiac manifestations include patent ductus arteriosus, septal hypertrophy, pulmonary hypertension, and pericardial effusions. They may follow a benign course, but of the 10 cases we report, 4 patients required surgical closure of the patent ductus arteriosus and 1 patient a pericardectomy. Long-term follow-up of these patients has shown reassuring neuro-developmental outcome and the emergence of a behavior phenotype including obsessive traits and anxiety.
