Solitary pulmonary nodules (SPNs) are increasingly detected with the widespread use of chest computed tomography (CT) scans. The management of patients with SPN should begin with estimating the probability of cancer from the patient's clinical risk factors and CT characteristics. ⋯ For patients in the intermediate range of probabilities, either CT-guided fine-needle aspiration biopsy (FNAB) or positron emission tomography (PET), is recommended. For those with a high probability of cancer, surgical diagnosis is warranted.

The recent article entitled "Principles of biopsy in suspected lung cancer: priority still based on invasion in the era of targeted therapy?" published in Journal of Thoracic Disease by Chen et al., concluded the principles of biopsy in suspected lung cancer should be prioritized in sequence based on weight in clinical management, acquisition of tissue, invasion, efficiency and cost. We reported a patient with a 30-year history of pulmonary silicosis, had been found no evidence of tumor after receiving a series of invasive examinations. We conclude that invasive examinations should be limited in patients with suspected lung cancer who had a defined history of underlying disease. Minimal invasion with careful acquisition of the appropriate quantity and quality of tissue should be adequate.

Red cell distribution width (RDW) is a variability of red cell sizes and has been associated with outcomes in many clinical settings. Its prognostic value in intensive care unit (ICU) has been reported but requires confirmation. The study aimed to investigate the role of RDW in predicting hospital mortality in critically ill patients. ⋯ RDW measured on ICU entry is associated with hospital mortality. Patients with higher RDW will have longer LOS in ICU. Repeated measurements of RDW provide no additional prognostic value in critically ill patients.

The vascular structure related compression of esophagus is rather rare. Aberrant right subclavicular artery accounts for the majority of the rare entity, while the thoracic aorta aneurysm is a more dangerous type, called as dysphagia aortica. Delay in diagnosis and treatment of the dysphagia aortica predisposes to rupture and death. ⋯ A quick diagnosis by using chest contrast computed tomography (CT) scan and angiography of heart was made, and followed by emergent surgery. In the process, there was no delay on the diagnosis and treatment. The patient is going on well in the follow up.
