[Juvenile metrorrhagia by Willebrand Jürgens syndrome (author's transl)]

Juvenile bleeding is a symptom frequently observed in a children's gynecologic outpatient clinic. In rare cases this symptom does not represent a disturbance of hormonal regulation systems, but may be due to a coagulopathy. We represent a patient of an age of 12 years, who was admitted with the diagnosis: juvenile metrorrhagia. The final diagnosis: Willebrand-Jürgens syndrome would be established after invasive examinations and a series of blood tests. The presentation of this case suggests to consider coagulopathies as a cause of bleeding in similar cases. The special condition should be tested in cooperation with hematologists.
