Hemorrhagic State Due to Surreptitious Ingestion of Bishydroxycoumarin

Abstract
Surreptitious use of an anticoagulant drug poses a baffling diagnostic problem, since the symptoms may simulate those of a congenital coagulation defect, vitamin K deficiency or liver disease. The first case of a bleeding disorder resulting from surreptitious ingestion of a prothrombinopenic anticoagulant drug was described by Stafne and Moe1 in 1951; subsequently, 8 additional cases were reported.2 3 4 5 6 In all 9, the correct diagnosis was established with great difficulty.
