Disseminated intravascular coagulation complicating urothelial malignancy.

Transitional cell carcinoma has rarely been reported to be associated with disseminated intravascular coagulation (DIC). We report a 55-year-old Chinese man who was diagnosed with transitional cell carcinoma with vertebral metastasis. He presented with severe anaemia and thrombocytopenia, and subsequent evaluation revealed features of DIC. Interestingly, he did not have fever, any localising symptoms or signs of infection. He was treated aggressively with transfusion of packed cells, platelets, intravenous vitamin K and fresh frozen plasma. Despite aggressive treatment, the coagulation abnormalities were resistant to correction. The patient continued to deteriorate and eventually died of cardiac arrest. This case illustrates that transitional cell carcinoma can also be associated with DIC, possibly due to the expression of certain unidentified procoagulant factors similar to the tissue factor responsible for DIC.
