Erlotinib (Tarceva(R)) Induced Hair Abnormalities / 대한피부과학회지

ABSTRACT

Erlotinib is a low-molecular-weight quinazoline derivative that inhibits the activation of epidermal growth factor receptor (EGFR) tyrosine kinase through competitive binding of the adenosine triphosphate binding domain of the receptor. Patients undergoing anti-EGFR therapy frequently present with cutaneous reactions like a sterile follicular and pustular rash, xerosis, pruritus, paronychia, hair abnormalities and mucositis, which can cause serious discomfort and negatively affect the compliance with anti-EGFR therapy. We report here on an interesting case of hair abnormalities induced by erlotinib (Tarceva(R)) and this presented as eyelash lengthening and hair curling in a 62-year-old woman.
