[Hypersensitivity vasculitis caused by ethyl biscoumacetate].
A case report of a 61-year-old patient with hypersensitive vasculitis caused by ethylbiscumacetate is presented. After the implantation of the artificial aortic valve the patient was treated with medigoxine, furosemide, dipiridamole, disopiramide, potassium chloride and ethylbiscumacetate. Among these drugs furosemide and ethylbiscumacetate are reported to cause hypersensitive vasculitis. On the basis of the past medical history, clinical and histological findings furosemide was ruled out as a causative agent. The diagnosis was confirmed by the skin biopsy and finding of a normal biologic activity of protein C. The discontinuance of all previous drugs and administration of methylprednisolone led to improvement in the skin lesions of the patient. The need for continuous anticoagulant therapy was the reason for fepromarone to be given, achieving good anticoagulant effect, without any side effects. According to the criteria of Karch and Lasagna the degree of connection between drug use and side effects in this case belongs to the category "probable".
