Background: lung cancer is the most common cause of cancer mortality worldwide. It is one of the cancers with worse prognosis, since it is usually diagnosed in advanced stages. Early detection, in the pulmonary nodule phase, would allow an earlier therapeutic intervention, improving prognosis and survival. Important diagnostic tools include chest radiography, computed tomography, fine needle aspiration, and a large number of differential diagnoses including benign and malignant lesions. Objective: to describe the clinical, radiological, histopathological and differential diagnoses of the solitary pulmonary nodule of subpleural location. Clinical case: a clinical case with a solitary pulmonary nodule and initial presumptive diagnosis of lung carcinoma is described; after being studied and performed lung lobectomy, diagnosed as an inflammatory cause, pneumonia. Conclusions: 95 % of solitary pulmonary nodules are neoplasias secondary to conditions with which a differential diagnosis can be established. The most frequent cause is granulomas secondary to infectious inflammatory conditions, following in order of frequency the cancer and within them the bronchogenic carcinoma.
