RT Journal Article SR Electronic T1 Cetuximab associated dermal filler reaction JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e228882 DO 10.1136/bcr-2018-228882 VO 12 IS 8 A1 Shivanshan Pathmanathan A1 Marcin Dzienis YR 2019 UL http://casereports.bmj.com/content/12/8/e228882.abstract AB A 52-year-old male patient with hyaluronic acid-based dermal fillers injected in his cheeks was diagnosed with glossotonsillary malignancy, and managed with concurrent cetuximab (epidermal growth factor receptor inhibitor) and radiation therapy. He developed significant inflammation around the dermal filler sites after first cycle of cetuximab which improved with dissolution of the dermal fillers with hyaluronidase. This suggests that cetuximab can lead to inflammation around the dermal filler sites, which can be treated with dissolution of the filler.
