Electronic cigarette, or vaping, product use-associated lung injury (EVALI) in a patient with testicular cancer: A case report

Electronic cigarette, or vaping, product use-associated lung injury (EVALI) is an increasingly recognized entity with the potential for severe pulmonary toxicity. We present the case of a young man first evaluated at a tertiary care center in the United States in 2019 with newly diagnosed testicular cancer with acute respiratory failure, which was initially attributed to possible metastatic disease but eventually determined to be related to EVALI. This case highlights the clinical features of EVALI, the potential diagnostic dilemma that can arise with EVALI when occurring in the setting of malignancy and the importance of inquiring about vaping use among patients with malignancy, especially in adolescents and young adults.
