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. CASE: Here we report a 13-year-old boy presenting with bullous emphysema and coexisting with a borderline testicular tumor. He had no complaints of cough, sputum, or shortness of breath. He had a past medical history of pneumonia five years ago. In order to elucidate the underlying lung pathology, a wedge lung biopsy was performed and the patient was diagnosed with PTL. Scrotum ultrasonography was performed because of hydrocele in both testes, and bilateral epididymal cysts with papillary solid projections were reported. Pathological examination of the epididymal tumor revealed a `Mullerian type borderline epithelial neoplasm` which is an analogue of the ovarian serous borderline tumor. CONCLUSIONS: In conclusion, we reported the youngest PTL case in the literature, a rare disease with unknown pathophysiology, presenting as bullous emphysema and coincidental Mullerian type borderline epithelial neoplasm. It is important to diagnose placental transmogrification of the lung in a child with bullous emphysema because compared to other cystic lung diseases it is a benign disease and if no additional malignity exists, lobectomy or pneumonectomy is the cure for the disease.

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. Although, coexistence of acute appendicitis and COVID-19 has been well documented, it is not clear whether appendicitis is a complication of COVID-19 or coincidence in children. A 13-year-old boy who developed acute appendicitis during the clinical course of COVID-19 is presented to discuss the possibility of causal relationship between appendicitis and COVID-19 in children.
