Successful treatment of epidermal growth factor receptor inhibitor–induced alopecia with doxycycline

EGFR: epidermal growth factor receptor NSCLC: nonesmall cell lung cancer INTRODUCTION Both scarring and nonscarring alopecias have been described with the long-term use of epidermal growth factor receptor (EGFR) inhibitors. Current treatments revolve around anti-inflammatory agents such as topical corticosteroid ointments, creams, and intralesional injections to reduce follicular inflammation. Unfortunately, none of these therapies are universally effective. Here, we describe a case of erlotinib-induced alopecia refractory to intralesional and topical corticosteroids that was successfully treated with doxycycline as a novel treatment approach for EGFR inhibitoreassociated alopecia.
