COVID 19 (coronavirus) causes respiratory infection which can potentially lead to pneumonia.
In some people with Sweet's syndrome (SS), but not all, respiratory infection can trigger SS.
In some cases of SS, but not most of the time, SS can directly affect the lungs. This is often misdiagnosed as bacterial pneumonia. Existing respiratory problems can increase your risk of developing pneumonia.

Radiological changes & histopathology.
Radiological changes of pulmonary Sweet’s syndrome include the presence of nodular, reticular or patchy infiltration, with or without effusion (Li et al, 2015: 342). Histopathologically, pulmonary Sweet’s syndrome is characterized by interstitial inflammation, oedema and mild fibrosis, in which a large number of neutrophils and occasional lymphocytes, macrophages and eosinophils infiltrate the alveoli.
