title: Lupus anticoagulant in myelofibrosis.
abstract: A patient with myelofibrosis who also demonstrates a lupus anticoagulant is reported. The presence of a circulating anticoagulant adds to the list of potential hemorrhagic diatheses in myelofibrosis and also demonstrates myelofibrosis to involve a system that may be separate from the myeloid elements of the bone marrow.
