A child presenting with bullous emphysema.

Background: Placental transmogrification of the lung (PTL) is a clinical spectrum varying from asymptomatic to severe pulmonary impairment; such as recurrent pneumothorax, bronchopneumonia, respiratory distress syndrome and chronic obstructive airway disease. PTL usually presents as a bullous lesion, and rarely can appear in nodule or cyst formation on chest imaging. PTL with giant bullous emphysema has a male preference, is more commonly unilateral and mostly affects one lobe, but can rarely involve more than one lobe.

Acute appendicitis during the clinical course of COVID-19 in a 13-year-old boy: Complication or coincidental?

Gastrointestinal symptoms appear to be one of the most common presentations of SARS-CoV-2 infection, later named COVID-19. The symptoms such as nausea, emesis, abdominal pain, and diarrhoea may be recognised as either a finding of COVID-19 or prominent presentation of multi-inflammatory syndrome in children (MIS-C). COVID-19 may present with acute appendicitis and/or may mimic its clinical findings.
