Abstract:
An 61-year-old woman presenting deep vein thrombosis and persistent positive anticardiolipin antibodies was diagnosed as antiphospholipid syndrome and treated with low molecular weight heparin. Before and after anticoagulant therapy, continuous positive fecal occult-blood was found asymptomatically. Colonoscopy confirmed rectal cancer. Antiphospholipid autoantibodies are non-specially positive in some malignances, especially in elder onset patients. Thus, routine screening of malignancies is strongly suggested.
