Abstract
Pulmonary aspergillosis and lung cancer rarely occur simultaneously. We report a 51-year-old male with cavitary lung carcinoma, in which aspergillus fumigatus was detected in the resected lung. The patient underwent a left upper lobectomy and lymph node dissection at the diagnosis of cavitary lung carcinoma. Microscopic examination revealed the wall of the cavity to be poorly differentiated squamous cell carcinoma, and a cavity containing a dark yellowish-gray mass to be branching septate hyphae consistent with Aspergillus. We consider from this and other reported cases that careful examination and observation are necessary in cases with pulmonary cavitary lesion, even if the cavitary lesion has been diagnosed as aspergillosis.
