We present a case of a 55-year-old female with breast cancer who developed radiation recall dermatitis (RRD) 3 years later after administration of levofloxacin. A vast majority of cases occur after administration of chemotherapeutic medications; however, a review of literature implicates increasing numbers of nonchemotherapeutic agents and supplements in RRD. Although the pathophysiology of RRD has yet to be elucidated, the implication of more nonchemotherapeutic agents may favor a drug hypersensitivity etiology. To our knowledge, this is the first report of RRD secondary to levofloxacin.
