Dermatological toxicity associated with the use of gilteritinib in relapsed acute myeloid leukemia with FLT3 mutation: a case report.

ABSTRACT

We present a case of a patient diagnosed with FLT3 mut+ acute myeloid leukemia with FLT3 and NMP1 mutations who did not respond to standard induction and consolidation treatment with chemotherapy. Due to the FLT3mut+ gene mutation and intermediate cytogenetic risk, treatment with gilteritinib is requested. After treatment she experienced a neutrophilic dermatosis and granuloma annulare that was resolved with gilteritinib dose reduction and specific treatment in coordination with the dermatology department.
