Pulmonary aspergillosis caused by Aspergillus flavus.

Bronchopulmonary aspergillosis is usually caused by Aspergillus fumigatus. The six cases from the Sudan reported here were due to Aspergillus flavus. Three of the patients had primary invasive disease, one had Aspergillus mycetoma in a pre-existing lung cavity, and two had allergic aspergillosis. A special feature of the invasive disease was the clinical and radiographic simulation of malignancy, particularly in one patient who had multiple disseminated nodules of fungal granulomata in the skin of the lower abdomen.
