Rare benign lung tumours presenting with high clinical suspicion for malignancy: a case series and review of the literature.

Clinical suspicion for malignancy in the presented cases arose from previous and current medical history of malignancy, family history of malignancy, and/or specific radiographic findings. This paper highlights the need for a multidisciplinary approach in the management of incidentally discovered pulmonary nodules. Excisional biopsy and pathohistological analysis remain the gold standard in confirming the presence of a pathologic process and determining the nature of the disease. Common features of the diagnostic algorithm utilized among the three cases include multi-slice computerized tomography, excisional biopsy via atypical wedge resection (if the nodule is peripherally located), and lastly, pathomorphological analysis using haematoxylin and eosin staining and immunohistochemistry.
