[A pulmonary mycotic sequestrum during invasive aspergillosis]

2 cases of mycetomas are presented as exceptional manifestations of invasive aspergillosis. Both patients had diagnosis of leukemia and neutropenia, secondary to chemotherapy. The clinical features were subacute and mainly fever, cough, dyspnea and multiple infiltrates with cavitations and balls of hyphae within cysts shown in chest x-ray. The precipitin tests were positive for A. fumigatus and A. flavus, and were correlated with the specimens of the bronchial brushing. One of the patients improved with antimycotics and normalization of neutropenia.
