Abstract

Hydroxyurea is utilized to treat myeloproliferative disorders, including essential thrombocythemia, polycythemia vera, and chronic myeloid leukemia. The most common adverse effects are hematological issues, gastrointestinal symptoms, and anorexia, while dermatological side effects are rare. We present a patient who developed a dermatomyositis-like eruption and melanonychia, induced by hydroxyurea, after receiving the drug for the treatment of essential thrombocytosis.
