Vaping-related pulmonary granulomatous disease.

The use of electronic cigarettes, or "vaping," has garnered significant popularity and attention in recent years. Its pulmonary and systemic effects have yet to be fully studied and quantified, and recent reports of vaping-related illnesses and deaths have brought the clinical consequences of vaping into the public spotlight. This report describes the case of a 34 year old woman who presented to clinic with new-onset cough and dyspnea, shortly after beginning to use electronic cigarettes. Imaging demonstrated new micronodular opacities and mediastinal lymphadenopathy, while pathology confirmed granulomatous disease. After she received counseling and successfully quit vaping, her symptoms resolved and repeat imaging demonstrated resolution of parenchymal findings and lymphadenopathy. This case report therefore presents a longitudinal narrative of reversible vaping-related pulmonary granulomatous disease.
