Recurrent and Fixed Neutrophilic Dermatosis Associated With Dasatinib.

BACKGROUND: Dasatinib is a tyrosine kinase inhibitor indicated for the treatment of chronic myeloid leukemia (CML). Skin rashes are common, occurring in about a quarter of patients treated, and are generally mild. The commonest rash is a keratosis pilaris-like eruption. A neutrophilic dermatosis has rarely been reported. OBJECTIVE: We report a patient whose CML was successfully treated with dasatinib and who several years later developed episodes of a neutrophilic dermatosis recurring at the same sites. CONCLUSION: This report extends the clinical spectrum of neutrophilic dermatoses to include dasatinib-induced recurrent and fixed erythematous plaques.
