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. Peter de Laat

Dr. Peter de Laat (1958) works at the Erasmus MC - Sophia Children’s Hospital as a general academic pediatrician since 1989.

Until 2013 he was Head of the medium care unit for pediatrics. He is educational coordinator pediatrics and a member of the training group pediatrics for the general pediatrics part. Special focus is on: education and training; vascular malformations, spina bifida, oncology and infectious diseases.

Ever since the start in 1994, he joined the multidisciplinary WEVAR team (Work group vascular malformations Rotterdam) together with pediatric dermatologist Suzanne Pasmans (previously Arnold Oranje until his retirement in 2013) and pediatric surgeon Hester Langeveld (previously Gerard Madern).

The last 20 years more than 1500 children with vascular malformations have visited the multidisciplinary WEVAR clinic. All new patients are seen by the whole team at once: pediatrician, pediatric dermatologist and pediatric surgeon to set the right diagnosis and define the best treatment.

Peter de Laat’s focus in the WEVAR team is on the systemic treatment of vascular tumors in children (hemangiomas, kaposiform hemangioendotheliomas and kaposiform lymphangiomatosis).


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.


Prof. Dr. Suzanne Pasmans

Suzanne Pasmans 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 furthermore she is the initiator of the Digital Children Skin House: (not yet in English).
She is president of the Children's Dermatology Group Domain of the Dutch Society of Dermatology and Venereology and operates within the guidelines developed for children with skin disorders such as Directive Skin and adolescent health, congenital nevi, and revision atopic eczema.

Dr. Wouter W. van der Schaar


Doctor van der Schaar worked from 1969 to 2000 as a clinical psychologist in the Dermatological Department of the (then) "Binnen Gasthuis" and later at the University Medical Center in Amsterdam until his retirement. His goal was broadening support for and research into the psychological factors that influence the course or development of (chronic) skin diseases. His work in this field resulted in a promotion to the post of advisor of serveral dermatological patient associations.
Aside from medical psychology, he is also involved in the treatment of Post Traumatic Stress Disorder (PTSD) in victims at home and abroad, and worked for 10 years at the Dutch Obesity Clinic (NOK) in Hilversum. He still treats patients with various problems.

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.


Prof. Dr. Peter Steijlen

Prof. Dr. Peter Steijlen is dermatologist and head of the dermatology department of Maastricht University Medical Center + (MUMC +). This department has a spearhead of genodermatology (hereditary skin diseases). There is a good collaboration with the Department of Clinical Genetics, Pediatrics and Child Neurology in the MUMC +. Monthly monodisciplinary and multidisciplinary consultation takes place in Maastricht. To save patients travel time there is also a consultation hour in Veldhoven. Prof. Peter Steijlen is also affiliated with the Catharina Hospital in Eindhoven; Patients with ichthyosis can also get advice at this location. In addition, scientific research takes place at the laboratory "Experimental Dermatology" under the guidance of Dr. Michel van Geel. The Dutch Federation of University Medical Centers acknowledges the MUMC + dermatology department as Expert Center for ichthyosen. This means that the facility will be further facilitated. The Expert Center is included in the European Reference Network Skin. Prof. Peter Steijlen studied medicine in Leiden. He studied dermatology in Groningen and Nijmegen. In Nijmegen he got his PhD on the topic "Monogenic Disorder Disorders" with specific studies in the field of diagnostics and treatment of ichthyoses. Steijlen has been the PhD supervisor of several dermatologists who got their PhD on the same pathology.


Dr. Maaike Vreeburg

Maaike Vreeburg is clinical geneticist in the MUMC+ in Maastricht (Netherlands). She has worked since 2003 at the outpatient department of clinical genetics. In 2004 she started, with colleagues, a multidisciplinary outpatient clinic of clinical genetics and dermatology departments for patients with questions about genetic disorders of skin, nails, teeth, hair and blood vessels of the skin (called genodermatosen).  In 2008 she completed her training in a clinical geneticist and has worked since then in this function in the MUMC.  Since May 2015 she is head of the outpatient clinic clinical genetics.
Vreeburg knew in recent years she needed to combine her clinical interest in the field of the genodermatology with scientific research. This resulted in December 2014 in a promotion with a dissertation titled "The multidisciplinary team: a simple strategy Genodermatosis to solve complex cases".
In addition to genodermatology, she takes care of children and adults with intellectual disabilities, neuro genetics and children's neurogenetics as focus areas. Not only the individual patient care, but also innovation of care for people with rare disorders, through training or research, in national and international levels, have her warm interest.
