A case with psoriasis-like lesions induced by olmutinib (HM61713) while treating epidermal growth factor receptor T790M mutant advanced lung adenocarcinoma.

Olmutinib (HM61713) is a third-generation tyrosine kinase inhibitor active against mutant EGFR, including T790M in nonsmall cell lung cancer. The most common side effect of olmutinib to date includes diarrhea, rash, nausea, and pruritus. To the best of our knowledge, it is the first case of psoriasis-like lesions that occurred after treatment with olmutinib. Although the pathogenesis for skin manifestations is presently unknown, we present this case to increase awareness of this unique cutaneous side effect. [ABSTRACT FROM AUTHOR]
