Blackberry-induced hand-foot skin reaction to sunitinib.

Sunitinib is an orally administered small molecule that was approved by the US Food and Drug Administration in January 2006 as monotherapy for the treatment of patients with advanced renal cell carcinoma (RCC) and patients with gastrointestinal stromal tumor after disease progression on or intolerance to imatinib mesylate. Data pooled from multiple sunitinib dose-escalation trials showed that sunitinib is associated with various adverse events, with HFSR occurring in up to 20% of patients. We describe a 48-year-old woman with a history of metastatic colorectal cancer treated with single-agent sunitinib who developed pain and tenderness in areas of friction secondary to Blackberry use, and was diagnosed with trauma-induced hand-foot skin reaction (HFSR) secondary to sunitinib therapy.
