A must diagnosis of persistent cough: chronic eosinophilic pneumonia (Carrington disease)

Identification of Complex Pneumonia during the Outbreak of COVID-19: Bacterial Pneumonia Combined with Acute Eosinophilic Pneumonia in Patients with Maintenance Hemodialysis

“…Guidance on Treating COVID-19 from National Health Commission of the People's Republic of China (P.R.C) suggests differentiation of COVID-19 from other varieties of pneumonia, including flu virus, adenovirus, respiratory syncytial virus, mycoplasma pneumonia infection, vasculitis, dermatomyositis, organizing pneumonia, and eosinophilic pneumonia (EP) [ 2 ]. Among these, EP has an incidence rate lower than 1/100,000 and is prone to misdiagnosis as an infectious disease, which will delay the diagnosis and treatment [ 3 , 4 ]. Chest computed tomography (CT) in acute eosinophilic pneumonia (AEP) patients found that all patients had a glass-like impermeable shadow and no special lesions [ 5 ], a characteristic similar to COVID-19, making it difficult to identify.…”
