Two Cases of Acneiform Eruption Caused by Epidermal Growth Factor Receptor Inhibitors / 대한피부과학회지

ABSTRACT

Epidermal growth factor receptor (EGFR) inhibitors are associated with unique and dramatical dermatological side effects. The most commonly encountered adverse effect is a mild skin toxicity characterized by a sterile follicular and pustular rash that may be treated empirically and usually does not require treatment modification. Secondary adverse reactions seen with anti-EGFR therapy include xerosis, pruritus, paronychia, hair abnormality, and mucositis. According to the Korean literature, there are no reports of acneiform eruption induced by erlotinib (Tarceva(R)). We report a case of acneiform eruption induced by cetuximab (Erbitux(R)) and a case of acneiform eruption induced by erlotinib (Tarceva(R)).
