Abstract
ABSTRACT: Hydroxyurea is an oral medication associated with painful, nonhealing ulcers, for which there is no effective treatment but permanent discontinuation of hydroxyurea. The authors present a case of leg ulcers that likely occurred as a result of hydroxyurea use in a patient with essential thrombocythemia. Topical treatment with allogeneic platelet-rich plasma and artificial dermis completely healed the leg ulcers without hydroxyurea cessation.
