Keywords: Radiation recall, Gemcitabine, Myositis, Side effect
Radiation recall phenomenon can appear as dermatitis, pseudocellulitis, panniculitis or myositis after the administration of certain drugs and develop in the skin and soft tissue at previously irradiated sites. Several drugs are associated with the radiation recall and gemcitabine is one of them. Gemcitabine-related radiation recall preferentially involves internal organs and can also be observed at the fibromuscular tissue in the radiation portal. Herein, we report two cases with gemcitabine induced radiation myositis. One patient with non-small cell lung carcinoma, and the other one with pancreatic carcinoma developed myositis in the previously irradiated site after administration of gemcitabine based chemotherapy.
