A rare cause of lower gastrointestinal bleeding: acquired hemophilia A

We present the case of a 71-year-old male with a medical history of hypertension, dyslipidemia, and acute myocardial infarction in 2007 who was taking low-dose aspirin and bemiparin 3500 IU every 24 hours. He was admitted to the Urology Service with recurrent hematuria 14 days after radical prostatectomy, which ceased after continuous bladder irrigation.
