Imatinib- and Nilotinib-Induced Lichenoid Eruption in Chronic Myeloid Leukemia: A Rare Case Report

Abstract

Imatinib and nilotinib are inhibitors of tyrosine kinases (TKIs) generated from the bcr-abl fusion protein, c-Kit, and platelet-derived growth factor receptors. Cutaneous adverse effects (AEs) of TKI are the most frequent non-hematological sequelae. In our case, the common molecular target raises the possibility that cross-intolerance, in which similar AEs occur with both agents, can arise. We hereby report a rare case report on cross-intolerance of cutaneous AEs of imatinib and nilotinib in chronic myeloid leukemia.
