Diffuse neonatal hemangiomatosis: a new constellation of findings.

Diffuse neonatal hemangiomatosis is a rare, frequently fatal disease characterized by multiple cutaneous and visceral hemangiomas. The skin, liver, lungs, intestines, and central nervous system are the most commonly affected organs. Death can result from high-output cardiac failure as a result of arteriovenous shunting. In this report we present a new constellation of findings in a patient with diffuse neonatal hemangiomatosis, namely, an absent corpus callosum, ectopia cordis (sternal agenesis) with median abdominal raphe, and tricuspid atresia.
