[A problematic case of dysfibrinogenemia in gynecology].

Following an hymenal incision in a thirtheen years old patient a haemostaseological examination was done. A hyperfibrinolysis was supposed. In spite of a good clinical recovery values remained pathological, so we had to suspect a dysfibrinogenaemie. Only a rapid examination of all attainable family members was able to secure the diagnosis: Dysfibrinogenaemie. Dysfibrinogenaemia is not a to rare case, that such a diagnostic problem may arise in every department.
