RESUMO
OBJECTIVES: We describe the experience of a busy metropolitan medical examiner's office in the United States and share our navigation of the COVID-19 autopsy decision-making process. We describe key gross and microscopic findings that, with appropriate laboratory testing, should direct a pathologist towards a COVID-19-related cause of death. MATERIAL AND METHODS: We performed a retrospective review of 258 suspected and/or confirmed COVID-19 associated deaths that occurred between March 5, 2020, and March 4, 2021. RESULTS: A total of 62 cases due to fatal COVID-19 were identified; autopsy findings included diffuse alveolar damage, acute bronchopneumonia and lobar pneumonia, and pulmonary thromboemboli. Nine additional decedents had a nasopharyngeal swab positive for SARS-CoV-2 and a cause of death unrelated to COVID-19. Forty-seven cases with COVID-19-like symptoms showed no laboratory or histopathologic evidence of SARS-CoV-2 infection; the most common causes of death in this group were hypertensive or atherosclerotic cardiovascular disease, complications of chronic alcoholism, and pulmonary thromboemboli unrelated to infection. CONCLUSIONS: The clinical findings associated with COVID-19 are not specific; a broad differential diagnosis should be embraced when decedents present with cough or shortness of breath. An autopsy may be indicated to identify a cause of death unrelated to COVID-19.
