Dovitinib is a novel multi-target tyrosine kinase inhibitor that inhibits vascular endothelial growth factor receptor-1-3, platelet-derived growth factor receptor-β, Fms-like tyrosine kinase 3, c-Kit and fibroblast growth factor receptor-1-3. This compound is currently being assessed clinically for treatment of various malignancies. In phase I and II clinical trials of dovitinib treatment for renal cell carcinoma, 20% of patients experienced cutaneous adverse events, although the specific type of skin rash was not documented. Here, we report two cases of multiple milia formation induced by dovitinib. We believe our cases are the first report mainly showing non-inflammatory cystic structure.
