Prof. Dr. Chantal van der Horst


Since 1985 - the beginning of her training as a plastic surgeon - Prof. Dr. van der Horst has been interested in the analysis and treatment of vascular malformations and hemangiomas. She also has an interest in congenital anomalies in general. She has been a staff member at the AMC since 1989. In 1990 she organized (along with the work group "Congenital Vascular Abnormalities") the ISSVA Congress (International Society for the Study of Vascular Anomalies) in Amsterdam. Since then, she has been very actively involved in the field of congenital vascular abnormalities internationally. Her doctoral thesis, entitled "Considerations on port-wine stains and Their treatment" speaks for itself.

Over the years she has collaborated with many others on research and published on congenital vascular anomalies. This collaboration consists of work with geneticists, dermatologists, other plastic surgeons, vascular surgeons, intervention radiologists and patient groups. Collaboration leads gradually to better understanding of the effects of congenital vascular anomaly for the patients as well as to further insights into the causes of vascular abnormalities. These developments are unfortunately slow.

Since 2000 Prof. Dr. van der Horst has been head of plastic surgery at the AMC and instructor of plastic surgeons who of course also gain knowledge and understanding of congenital vascular anomalies.

Dr. Charlene Oduber


Doctor Charlène Oduber finished her doctorate on 12 January 2011 on Clinical aspects of vascular malformations deregulated growth. This included a clinical and genetic study of congenital vascular malformations combined with locally impaired growth of bone and soft tissue. This is a joint venture between Academic Medical Center in Amsterdam and the Academic Hospital Maastricht. She is also medical advisor to the Klippel-Trenaunay Foundation Netherlands SKTN. She has given national and international presentations on this subject and won various awards. She is also co-author of a chapter in the textbook Phlebology by Professor Neuman.

She completed her medical training in Leiden and graduated cum laude. In 1996 she graduated from the University of Amsterdam on IgE -dependent histamine -releasing activity, and has a degree as an immunologist. At the Institute Curie, Inserm, Paris she studied molecular biological research. In 2000 she completed training as a Dermatologist /Venereal in Utrecht. Subsequently, she went on to study at UMC Utrecht Wilhelmina Children and continued to focus on children's allergy and dermatology research done within the pediatric dermatology (especially food allergies, eczema, vascular abnormalities, congenital skin lesions) . She has also developed innovative care for children with skin disorders (for which she has received from the NPCF and prices in adds ) and she is also the initiator of the Digital Children Skin House: (not yet in English).

Prof. Dr. Maurice Steensel


Maurice van Steensel (1969) studied medicine at the Catholic University of Nijmegen. During his studies and after graduation he worked as a researcher at the Department of Clinical Genetics performing molecular research. An interest in hereditary skin diseases had already seized him when the opportunity presented itself, so he shifted from genetics to dermatology and trained to become a dermatologist. Together with Prof. Peter Steijlen he ran the outpatient clinic for hereditary disorders in Nijmegen. In 2003 he moved into dermatology in Maastricht, where in 2005 he obtained his doctorate in the molecular genetics of inherited skin disorders. In 2006, Dr. Steensel concluded his dermatology training.  He directs the research into hereditary skin diseases and the laboratory for experimental dermatology that he and Dr. Michel van Geel began in 2003. At Maastricht University Medical Center, there are now three well-attended clinics for hereditary skin diseases where people from all over the world attend.
