[A 65-year-old female patient with breast cancer accompanied by thrombocytopenia and hyperfibrinolysis]. / 65-jährige Patientin mit Thrombopenie und Hyperfibrinolyse bei Mammakarzinom.

Tumor diseases can be accompanied by paraneoplastic syndromes. Low platelet counts and hyperfibrinolysis led to the diagnosis of recurrent breast cancer in this case. A tumour disease with disturbed hemostasis caused by both plasmatic coagulation and thrombocytopenia has not yet been reported.
