Case ReportsLate presentation of lung adenocarcinoma in a stable solitary pulmonary nodule: A case presentation and review of the literature.
A 67-year-old patient has been followed by our pulmonary clinic for Chronic obstructive pulmonary disease (COPD) and a stable pulmonary nodule. Solitary pulmonary nodule (SPN) was detected on the lung cancer screening by low dose computed tomography (CT) scan of the chest. It remained stable on repeat CT scan at 6, 12 and 24-months interval. ⋯ The patient then underwent right upper lobectomy followed by chemoradiation therapy. Current guidelines do not recommend follow up for a solitary pulmonary nodules less than 6 mm nodule if it remains stable for 12-24 months. Our case report of the late presentation of lung adenocarcinoma in a stable solitary pulmonary nodule suggests the need to exercise increased caution in the management of incidental pulmonary nodules.

Case ReportsA case of lymphocytic interstitial pneumonia presenting with a ground glass nodule as an initial finding.
A 65-year-old woman had a ground glass nodule, which was suspicious for lung cancer, in her right lung S6 by chest computed tomography. For diagnosis, video-assisted thoracoscopic surgery was performed, and the specimen showed a pathological pattern of lymphocytic interstitial pneumonia (LIP). ⋯ Subsequently, no other underlying diseases associated with LIP developed. The ground glass nodule was the initial lesion of LIP.

Case ReportsRecurrence of emphysema post-lung transplantation in a patient with alpha 1 antitrypsin deficiency (AATD).
The genetic disorder alpha 1 antitrypsin deficiency (AATD) results in reduced levels of alpha 1 antitrypsin (AAT) in the lung and an imbalance between AAT anti-protease activity and the activity of proteases that degrade elastin and connective tissues. This imbalance commonly leads to the excessive proteolysis of structural tissue of the alveoli, causing chronic obstructive pulmonary disease (COPD)/emphysema. ⋯ Recurrence of COPD/emphysema was observed in a patient with AATD 2 years after initial successful lung transplantation and cessation of AAT therapy who recommenced smoking after no signs of disease at the 1-year assessment. This case demonstrates that smoking cessation is critical in patients with AATD, even after lung transplant, and it highlights that patients with AATD may benefit from AAT therapy post-lung transplant.

Case ReportsSuccessful recovery from COVID-19 pneumonia after receiving baricitinib, tocilizumab, and remdesivir. A case report: Review of treatments and clinical role of computed tomography analysis.
The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic, threatening global public health. In the current paper, we describe our successful treatment of one COVID-19 pneumonia patient case with high mortality risk factors. Our experience underlines the importance of the use of a multidisciplinary therapeutic approach in order to achieve a favorable clinical outcome. Further, enhancing the capability of the COVID-19 diagnosis with the use of the chest imaging modalities is discussed.

Case ReportsRapidly progressive organizing pneumonia associated with COVID-19.
We report a case of clinically diagnosed secondary organizing pneumonia (SOP) associated with coronavirus disease 2019 (COVID-19). A 70-year-old woman who had been diagnosed with COVID-19 was admitted to Hokkaido University Hospital. Although her fever, cough, dyspnea, and serum C-reactive protein levels improved, she developed rapidly progressive respiratory failure and computed tomography revealed the development of bilateral lung consolidation. ⋯ Blood biomarkers for interstitial lung disease, Krebs von den Lungen-6 (KL-6) and surfactant protein D (SP-D), showed different responses during the clinical course of her disease. Evaluation of serial changes in levels of KL-6 and SP-D may help diagnose and monitor COVID-19-associated organizing pneumonia (OP). Clinicians should be aware that SOP can develop in response to COVID-19 and that these patients may benefit from the use of steroids.
