The size, morphology, and number of nodules are helpful parameters for differential diagnoses in many cases, whereas more interventional methods are required to clarify the etiology of progression at follow-up. Benign lesions such as atypical pneumonia, tuberculosis, atypical mycobacteria, inflammatory granuloma, rheumatoid nodules, and atypical bronchoalveolar hyperplasia are also common in immunocompromised patients who underwent multiple cycles of chemotherapy.MedicineCancerBook Chapterhttps://www.scopus.com/inward/record.uri?eid=2-s2.0-85025440220&doi=10.1007%2f978-3-319-26012-9_40&partnerID=40&md5=9fffbdc98b8a43a892d0e7bf8cd5fc2b2150
