Ponatinib is a third-generation tyrosine kinase inhibitor (TKI) which is used as a chemotherapeutic agent in the treatment of chronic myeloid leukemia. Despite being relatively less toxic than other older TKIs, it still has various adverse effects including skin rash. Cutaneous manifestations have varied presentations such as lichenoid, pityriasiform, ichthyosiform, and pityriasis rubra pilaris-like rash. We present here a 35-year-old male with chronic myeloid leukemia who developed a unique pattern of symmetrical rash to Ponatinib which was successfully treated with topical tacrolimus and reduction of dose of the drug.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
