Larsen syndrome shows a broad spectrum of clinical manifestation ranging from a lethal form of the disorder to a mild clinical expression with absence of major diagnostic features. Here we show that even intrafamilial manifestation may vary extremely to the point that Larsen syndrome in a father has been diagnosed only by typical sonographic features in an affected fetus.

Our findings lead to the tumor, as source of angiogenic chemokines, is most important for recruiting CD34(+)FLK-1(+ )EPCs during breast cancer development. Therefore circulating endothelial progenitor cells may work as a new diagnostic tool in the screening and diagnosis of breast cancer.

Advances in ultrasound technology and sonographer’s experience lead to the description of many rare syndromes and malformations through prenatal diagnosis. Diaphragmatic hernia is a rather common malformation but can be an indicator of different syndromes. We report the prenatal diagnosis of lethal multiple pterygium syndrome type II which has been established in the 34th week of pregnancy. The sonographically detectable symptoms consisted of polyhydramnios, hygroma colli, diaphragmatic hernia, scoliosis, short forearms, hypokinesia of the fetus and pterygia over the large joints. Labour was induced in the 34th week of pregnancy; the neonate died shortly after vaginal delivery as a result of the pulmonary hypoplasia. A multidisciplinary approach in prenatal assessment may help to clarify difficult diagnostic problems and may be of direct benefit for the pregnant patient.
