Figure 4. Macromorphology findings of COVID-19 patients.

(a) Pneumonectomy of patient one showed strong congestion with liquids and hemorrhages. The tissue consistency was fragile. (b) Cut surface of lung tissue in higher magnification as shown in (a). The pleura shows further hemorrhages. (c) Pneumonectomy of patient seven showed a more solid lung tissue without congestion. The tissue consistency was very firm. (d) Cut surface of lung tissue in higher magnification as shown in (c). Lung tissue was retracted adjacent to the bronchus. (e) Pale pleura visceralis of the lung of patient 6 with disseminated hemorrhages and signs of disturbed ventilation. (f) Nodular transformation of lung tissue as phenomenon of fungal superinfection in patient 3. (g) Hemorrhagic lung infarct in patient 4 due to a thrombembolus in a pulmonary artery branch. (h) Anemic spleen infarct due to a clotted small artery in patient 4. (i) Fulminant stasis and thromboses in the periprostatic plexus in patient 4. (j) Cerebellar infarction (hemorrhagic) in patient 9.
