Unleashing the mysterious link between COVID-19 and a famous childhood vasculitis: Kawasaki disease. Postmortem examination of COVID‐19 patients reveals diffuse alveolar damage with severe capillary congestion and variegated findings in lungs and other organs suggesting vascular dysfunction. The predominant visceral macroscopic changes were enlargement of lymph nodes in the pulmonary hilar and abdominal cavity to varying extents, diminished size of the spleen (9.8 × 5 × 3 cm, 8.2 × 4.1 × 2 cm, and 7.4 × 3.5 × 2 cm, respectively), and reduced weight of the spleen (110 g, 123 g, and 114 g, respectively). An example is hyaline cartilage, a transparent, glossy articular joint cartilage. Recent studies indicate that the cellular receptors for CV (CD13) exist predominantly in mononuclear cells, venular endothelial cells, epithelial cells in the respiratory tract and renal tubules, fibroblasts, brush‐border cells of the intestine, stromal cells in the bone marrow, and the synaptic membrane of the central nervous system. Neurological Involvement with COVID-19 Review. The main pathological changes involve the lungs. The lungs, immune organs, and systemic small vessels are the main targets of virus attack, so that extensive consolidation of the lung, diffuse alveolar damage with hyaline membrane formation, respiratory distress, and decreased immune function are the main causes of death.
