A Rare Case of Malignant Lung Cancer in a 20-Year-Old Patient: Possible Diagnostic Pitfalls

We present a case of a 20-year-old male with a rare form of malignant lung cancer. The patient had a long history of respiratory symptoms that have been repeatedly treated as a pulmonary infection. Despite several hints of the ineffectiveness of the therapy, the diagnosis and definitive surgical treatment were made 4 months after the onset of symptoms. Our aim is to highlight the importance of an efficient diagnostic process within multidisciplinary discussion and to warn clinicians on potential pitfalls related to unusual clinical presentation.
