A not so harmless mass: Kaposiform hemangioendothelioma complicated by a Kasabach-Merritt phenomenon.

A vascular mass localized in the face and the neck was displayed by ultrasonography in a 38-week-old male fetus. At birth, the mass was bulky and purplish. The newborn breathed spontaneously but with severe desaturation.

[A traumatic cervical spine injury in children?].

Cervical spine injuries are a regular reason for consultation in general practice or pediatric emergencies. In many cases, it is difficult to distinguish between whether or not a radiological assessment is necessary. We propose in this article a management strategy based on clinical scores simple to achieve in order to avoid unnecessary radiological examinations for children.

[Meckel's diverticulum : state of the art].

The persistence of the embryonic vitelline duct can lead to omphalomesenteric duct anomalies. A wide variety of anomalies, depending on the remnant segment and its degree of involution, may occur as a result of the omphalomesenteric duct failing to obliterate completely. The most frequent omphalomesenteric duct anomaly is Meckel's diverticulum, which is present in approximately 2-3 % of the population.

[A new treatment for vascular anomalies: Six cases treated with rapamycin].

Vascular anomalies (VAs) result from the defective development of the embryonic vascular system and feature dysplastic malformed vessels, which are not always apparent at birth. They do not regress over the patient's lifetime; they usually have commensurate growth during childhood and may worsen over time if not treated. VAs may cause chronic painful swelling, bleeding, functional deficits or vital structure obstruction.

Concomitant nodal involvement by Langerhans cell histiocytosis and Hodgkin's lymphoma.

A 10-year-old girl with a family history of Hodgkin's lymphoma presented with a 2 month history of cervical lymphadenopathy and weight loss. Biopsy indicated concomitant nodal involvement by Langerhans cell histiocytosis and Hodgkin's lymphoma. Such an association is rare, especially so in children, but is not an isolated phenomenon, thereby prompting the question of whether Langerhans cell histiocytosis is a reactive or a neoplastic process.
