Resumen

We present the case of an 85-year-old woman who was diagnosed with essential thrombocytosis; and, who, after six months receiving therapy with hydroxyurea, she noticed her fingernails turned dark. The exact mechanism for this occurrence is still unknown. We should pay attention to this unusual complication that may lead to interrupt or modify therapy.
