Pathology cases – covid-19 pneumonitis

Here are some photomicrographs of the lung of a 65-year-old man who came into the hospital short of breath.  He tested SARS-Cov-2 positive.  His condition deteriorated, complicated by deep vein thrombosis, pulmonary thromboemboli, and cerebrovascular accident.  At autopsy, he had, among other things, characteristic lung findings of diffuse alveolar damage with some organization as well as scattered fibrin microthrombi.

Here are some photomics of the lung.

Note that the aveoli are largely obliterated.

  1. Billo,
    Beautiful presentation!! Was that your own case?
    Question: Would an anticoagulant such as Eliquis possibly have been appropriate treatment?
