[Aspergillosis with non-cavitary lung cancer]

Growth of Aspergillus was observed in the necrotic tissue of non-cavitary lung cancer. Case 1 was a 60-year-old male complaining of cough and fever and was found to have left lower lobe atelectasis on chest X-ray. Bronchoscopic examination showed the yellow soft lesion occluding the left upper and lower lobe bronchus. Specimen from the lesion demonstrated adenocarcinoma and hyphae of Aspergillus in the necrotic tumor. Case 2 was a 53-year-old male who was found to have a left upper lobe mass by chest X-ray screening. Bronchoscopic examination showed the yellow polypoid lesion occluding the left upper division bronchus. Pneumonectomy was done and resected specimen of the lesion demonstrated adenocarcinoma and the hyphae of Aspergillus growing in both necrotic tissue and cancer tissue. As both patients had hyphae of Aspergillus in the necrotic tumor, it is considered that the presence of necrosis may cause the growth of Aspergillus.
