Diffuse neonatal hemangiomatosis associated with Simpson-Golabi-Behmel syndrome: a case report.

Diffuse neonatal hemangiomatosis (DNH) is a rare disorder characterized by multiple cutaneous and visceral hemangiomas that usually presents in newborns and has a high mortality rate. While previously reported cases of DNH describe multiple cutaneous hemangiomas, we present a patient with a single hemangioma of the ear, who also had DNH of the central nervous system and visceral organs. Furthermore, in this report we present a new constellation of findings, namely, a Simpson-Golabi-Behmel syndrome (SGBS). The practical implication on the basis of the experience with our patient is the need to ensure adequate diagnostics for patients with large hemangiomas as well as for patients with multiple cutaneous hemangiomas, because DNH also can occur in single hemangiomas in rare cases.
