Aspergillus fumigatus in A Fine Needle Aspiration of a Cavitary Lung Lesion

Fine needle aspiration cytology (FNAC) can be quite helpful in distinguishing malignancy from infection. Fungal elements may be detected using routine stains as in our case. The present case describes a 64-year-old male presented with chills and mild dyspnea on exertion after completing four cycles of chemotherapy for stage IIA adenocarcinoma of the lung. Use of special stains to enhance cytomorphological changes in conjunction with microbiology culture results is critical to identify the specific microorganism.
