Many questions on the clinical management of coronavirus disease (COVID-19) remain unanswered, and data on corticosteroid therapy as a choice of treatment are mixed. We present the clinical course of seven patients, review the previous evidence, and discuss management.

We present the case of a 43-year-old man with suspected tuberculous pleurisy (TP). Thoracoscopy under local anaesthesia showed the entire pleura with scattered nodules. Nodules were biopsied by conventional biopsy forceps, but the tissue sample was small, so a cryobiopsy was performed. Histological analysis of the conventional biopsy forceps and cryobiopsy specimen showed inflammation with lymphocytes and caseating granulomas. Tissue culture of conventional biopsy forceps was positive for Mycobacterium tuberculosis , and all sensitivity tests were positive. But, the tissue culture of the cryobiopsy sample was negative. There is a possibility that cryobiopsy is not useful for tissue culture for TP.

We present a patient with endobronchial tuberculosis (TB) polyps for which initial acid-fast bacilli staining and TB complex DNA polymerase chain reaction yielded negative results. Histopathology showed non-caseating granulomatous inflammation and the diagnosis was ultimately achieved four weeks later when bronchial washing cultures yielded Mycobacterium tuberculosis , thus highlighting the challenges in achieving a timely diagnosis.

Adenocarcinoma (ADC) is the most common form of lung cancer; however, some other types of lung cancer, such as pulmonary pleomorphic carcinoma (PC), can sometimes mimic ADC. Here, we present a patient with initial diagnosis of pulmonary ADC later diagnosed with PC.

Multisystem Langerhans cell histiocytosis in an adult non-smoker treated with steroid therapy for a subacute exacerbation: a case report and review of the literature.

We herein report a case of a patient who developed massive atelectasis by mucoid impaction during treatment with anti-interleukin (IL)-5 receptor antibody.

We report a case of chylothorax due to tuberculosis lymphadenitis with distinct evidence of enlarged lymphatic duct macroscopically.

A mediastinal mass in patients with a history of asbestos exposure should raise the suspicion of malignant mesothelioma.

Here, we describe a case of complete occlusion of right pulmonary artery seen in a patient with Behçet disease.

We report a rare case of post-operative pulmonary artery pseudoaneurysm. In such instance a prompt diagnosis and adequate treatment are essential to avoid catastrophic complications.

We report a patient in whom a supernumerary venous branch draining the superior segment of the right lower lobe into the left atrium (accessory V6) was accidentally discovered near the level 7 nodal packet thus avoiding complications during surgery. The anomalous vessel was retrospectively identified on chest computed tomography (CT) scan.
