Imatinib-induced eruptive nevi.

Imatinib mesylate is a tyrosine kinase inhibitor used in the treatment of a variety of oncological conditions. It has been associated with a spectrum of pigmentary cutaneous side effects. Despite the well-known association of eruptive melanocytic nevi with the use of other tyrosine kinase inhibitors, this phenomenon has not been linked to the administration of imatinib. We present the first case of imatinib-induced eruptive nevi in an 18-year-old patient with acute lymphocytic leukaemia in remission.
