Abstract
An 80 years old male patient was admitted in our hospital with massive haematomas in the left forearm, chest and abdominal wall accompanied by intense back pain symptoms. Laboratory evaluation showed anemia, mild thrombocytopenia and elevated lactate dehydrogenase and alkaline phosphatase levels and normal concentrations of all the other biochemical parameters. Study of the coagulation status demonstrated prolonged thrombin time (TT), low fibrinogen levels – 0.98 g/l while plasminogen, antihrombin III(AT III) and protein C levels were found to be within normal range. Computed tomography scans of the head, chest and abdomen showed an enlarged infiltrative prostate, osteolytic bone lesions in vertebras L5-S1 and a large haematoma of the abdominal wall as the only pathologic findings. Very high levels of the prostate specific antigen indicated the possible existence of a prostate carcinoma with metastases to the vertebral column that resulted in elevated alkaline phosphate and lactate dehydrogenase levels. There were no signs of liver involvement and impaired hepatic synthetic function. Based on the results of the laboratory tests we concluded that the cause of the bleeding disorder in our patient was an acquired hypofibrinogenemia, which is a very rare paraneoplastic phenomenon. The patient was treated with daily transfusions of cryoprecipitate with no long-term improvement. Then the specific anti-tumor therapy (ciproteron acetate) was initiated, and two weeks later, fibrinogen concentration and TT returned to normal values.
