title: Increased releasable vascular plasminogen activator and a bleeding diathesis.
abstract: A 66-year-old man with metastatic prostatic carcinoma treated with high-dose (5 mg) diethylstilbestrol therapy underwent orchiectomy to allow discontinuation of estrogen. An extensive ecchymosis developed postoperatively in an area covered by elastic dressing tape; subsequently, it was learned that the patient had a recent history of frequent ecchymoses with mild trauma that proceeded to vesiculation. His alpha2-antiplasmin level was 132 percent, fibrin split products 4 micrograms/ml, and fibrinogen 293 mg/dl; routine coagulation results were normal. However, the level of releasable vascular plasminogen activator in a specimen drawn prior to surgery was 3.6 CTA units/ml, the highest value ever reported in this laboratory.
