Vasculitis due to gemcitabine.

We report the first occurrence of gemcitabine-induced vasculitis. It concerns a 45-year-old man diagnosed with non-small lung cancer since 2 months. After the first cycle of chemotherapy, consisting of gemcitabine and cisplatin, he developed myalgia and swelling of arms and legs with impairment of movement. This re-occurred during the second cycle of chemotherapy. Further anemia, elevated ESR and increased creatininephosphokinase. A surgical biopsy showed leucocytoclastic vasculitis and necrosis of muscle tissue. The chemotherapy was stopped and the complaints disappeared and did not return.
