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.

Acute amiodarone toxicity after a single dose of intravenous amiodarone is very rarely seen. We report the case of a 64-year-old Chinese man who presented with atrial fibrillation and fluid overload due to congestive cardiac failure. He was treated with a single bolus dose of intravenous amiodarone, after which he developed elevated serum transaminases, coagulopathy, thrombocytopenia and acute renal failure. His parameters returned to normal after 25 days and his recovery was uneventful.
