Skin and oral lesions associated to imatinib mesylate therapy.

INTRODUCTION: Imatinib mesylate is a tyrosine kinase inhibitor used to treat chronic myeloid leukemia (CML) throughout all the phases of the disease. In most cases, this drug is well tolerated; however, some cases experience side effects. RESULTS AND DISCUSSION: Skin rashes and oral lesions are uncommon and appear to be dose-dependent. The authors report two cases of CML Ph+ in chronic phase patients who presented skin and oral lesions probably induced by imatinib therapy.
