title: [Haematological complications of prostatic cancer: 2 cases, one revealing the neoplasia].
abstract: BACKGROUND
  We report two cases of patients with prostate cancer who underwent haematological complications from the disease.
  
  
  METHODS
  Diffuse intravascular coagulopathy (with thrombopenia) was observed in two patients (55 and 59 years-old) diagnosed with prostate cancer. In one patient who had normal prostate at clinical examination, thrombopenia with incomplete diffuse intravascular coagulopathy and biological inflammatory led to diagnosis. It was initially controlled by hormonal therapy and secondary by chemotherapy. In the other patient diffuse intravascular coagulopathy followed introduction of hormonal therapy and lead to the patient's death.
  
  
  CONCLUSIONS
  Patients with metastatic hormone-refractory prostate carcinoma may have life-threatening coagulation complications due to their disease. Diffuse intravascular coagulopathy is the most frequent coagulation complication. Other coagulopathies associated with prostate cancer are thrombocytopenic thrombotic purpura, thrombosis, Trousseau's syndrome and acquired factor VIII inhibitor development. Usually these haematological manifestations complicate the course of the disease and appear to have a bad prognosis. But thrombopenia or haematologic features may lead to the diagnosis of medullary metastatic prostatic cancer, even if the prostate appears normal at the initial clinical examination.
