[Hospital infection of bronchopulmonary aspergillosis in infants and small children].

Routine histological investigations of the lungs of 38 children led to the discovery during the second half of 1970 of 4 cases of pulmonary aspergillosis in hospitalized children between 3 1/2 weeks and 2 years of age. Those cases represented 10.5% of all children, autopsiated during this period with an hospitalization period of more than 7 days. In two cases Aspergillus filaments did not invade pulmonary tissue, but in the two other cases Aspergillus mycelium had invaded the walls of adjacent pulmonary arteries with resultant arteritis, thrombosis and hemorrhagic infarction. The author believes, that the mycoses were acquired by inhalation of contaminated air. But he can not base this supposition of factual evidence.
