CASALLO BLANCO, S. et al. Lung adenocarcinoma feigning and interstitial lung disease of a 30-year-old man. An. Med. Interna (Madrid) [online]. 2007, vol.24, n.6, pp.289-291. ISSN 0212-7199.

A case of a 30-year-old man is presented. He had a past medical history of asthma and presented with cough, shortness of breath, fever and chest pain. The chest X-ray showed cardiomegaly and a interstitial pattern. The echocardiogram revealed a severe pericardial effusion that required performing a pericardiocentesis. A CT scan showed mediastinal adenopathies and reticulonodular intertitial pattern. A bronchoscopy could not be completed because of non-tolerance. Finally a lung biopsy allowed us to reach a final diagnosis of lung adenocarcinoma. Following, some aspects of lung cancer in young people are commented, especially its incidence, histology, symptoms and a prognosis. A few aspects of the interstitial lung disease are also addressed and the differential diagnosis with lymphangitic carcinomatosis.
