Abstract
A healthy 21-year-old woman was presented to our outpatient clinic with an asymptomatic swelling on her left arm. She reported the administration of two doses of BNT162b2 mRNA vaccination at the lesion site earlier. The pathology report confirmed the diagnosis of pilomatricoma. Previously, needlestick trauma and various immunisations have been attributed to the development of pilomatricoma. We present this case to emphasise the possible association between BNT162b2 mRNA vaccination and pilomatricoma development. The role of persistent inflammation is also discussed.
