ABSTRACT

Sunitinib is a multi-targeted kinase inhibitor showing benefits in patients with renal cell carcinoma, and gastrointestinal stromal tumor. Sunitinib may cause various cutaneous toxicities. The most characteristic and common cutaneous toxicity is hand-foot skin reaction. Lesions are characterized by yellow painful callus like hyperkeratosis surrounded by a rim of erythema, they are well-demarcated and localized especially over pressure areas. A 54-year-old male patient with a history of renal cell carcinoma developed painful eruption twenty days after oral sunitinib had been started on 50 mg daily. Dermatological examination showed multiple, yellow, hyperkeratotic plaques with erythematous halos on palms, and soles. The patient was diagnosed as hand-foot skin reaction due to sunitinib due to descriptive clinical findings. Hand-foot skin reaction can greatly affect patients’ quality of life and treatment dosages. Early diagnosis and timely treatment of hand-foot skin reaction will be vital to ensure maximum potential of these drugs.
