Tyrosine kinase enzymes are an attractive target for anticancer therapies. Tyrosine kinase inhibitors (TKI) are well tolerated; somehow severe systemic side effects are rarely seen during treatment. Toxicities of skin and appendages may lead to poor compliance, psychosocial inconvenience, and drug interruption. Changes of the hair can arise following cures with TKI. Nilotinib, a second-generation TKI, has been responsible for various cutaneous side effects including different clinical presentations of alopecia (scarring and nonscarring forms). This paper reports the case of a 45-year-old male diagnosed with chronic myelogenous leukemia (CML) treated with nilotinib, who presented with a keratosis pilaris (KP)-like eruption, autoresolutive alopecia areata plaque of the wrist and diffuse eyebrow thinning. To date, eight cases of nilotinib-induced KP were reported. However, none of them was associated with alopecia areata. Hence, physicians need to be aware of this new cutaneous side effect and investigating the reason of this phenomenon requires additional studies. Key words: Alopecia areata, chronic myelogenous leukemia, keratosis pilaris, nilotinib
