Figure 6. Micromorphology lung findings of COVID-19 patients.

Figure 6.

(a) Lung tissue with minimal emphysematous changes derived from the upper lobes without detectable viral loads (patient 2; HE). (b) Severe hemorrhagic pneumonia in specimens from the lower lobes with high viral loads (patient 2; HE). (c) Vasculitis-like changes around pulmonary artery branches (patient 4; HE). (d) Damaged lung tissue with hemostasis and inflammatory changes adjacent to the pulmonary artery branch (patient 4; HE). (e) Strong lymphocytic-predominant infiltration of lung tissues with hemorrhagic and interstitial edema (patient 7; HE). (f) Higher magnification of the lymphocytic-predominant infiltrate (patient 7; HE). (g) Lung tissue with a large nucleated cell in an alveolar capillary, suggestive for a megakaryocyte (arrow; patient 9; HE). (h) The same tissue after immunostaining against CD61 (patient 9; immunostaining CD61).
