Lung Biopsy Findings in Severe Pulmonary Illness Associated With E-Cigarette Use (Vaping).
American Journal of Clinical Pathology 2020 January 2
OBJECTIVES: The aim of this report is to describe the lung biopsy findings in vaping-associated pulmonary illness.
METHODS: Lung biopsies from eight patients with vaping-associated pulmonary illness were reviewed.
RESULTS: The biopsies were from eight men (aged 19-61 years) with respiratory symptoms following e-cigarette use (vaping). Workup for infection was negative in all cases, and there was no evidence for other etiologies. Imaging showed diffuse bilateral ground-glass opacities in all patients. Most recovered with corticosteroid therapy, while one died. Lung biopsies (seven transbronchial, one surgical) showed acute lung injury, including organizing pneumonia and/or diffuse alveolar damage. Common features were fibroblast plugs, hyaline membranes, fibrinous exudates, type 2 pneumocyte hyperplasia, and interstitial organization. Some cases featured a sparse interstitial chronic inflammatory infiltrate. Although macrophages were present within the airspaces in all cases, this feature was not prominent, and findings typical of exogenous lipoid pneumonia were absent.
CONCLUSIONS: The histopathology of acute pulmonary illness related to e-cigarette use (vaping) is characterized by acute lung injury patterns, supporting the contention that vaping can cause severe lung damage.
