Bullous pilomatricoma is a rare form of pilomatricoma, always presenting with firm subcutaneous nodules with a bullous appearance. In this study, we report a 9-year-old Chinese presenting girl with bullous pilomatricoma after influenza vaccination.Keywords: bullous pilomatricoma, calcifying epithelioma of Malherbe, influenza vaccination
