Organizing pneumonia (OP) promptly responds to corticosteroids. However, a minority of patients demonstrate corticosteroid resistance or relapse on corticosteroid tapering. The following case reports describe post COVID-19 OP patients pre-vaccination era with clinically inadequate response to corticosteroids but who improved after the addition of mycophenolate mofetil (MMF, Mycofit®).

We describe infective pneumonia secondary to disruption of the bronchial epithelium from a severe case of Toxic Epidermal Necrolysis Syndrome (TENS). This syndrome was due to Ciprofloxacin which is a very rare cause. Our patient recovered well with conventional treatment of TENS and pneumonia.

Liposuction is one potential cause of fat embolism syndrome (FES). Liposuction-induced FES is a rare, but life-threatening condition. Here we report the case of a 29-year-old woman who developed FES suddenly during a liposuction operation in a cosmetic medical clinic and achieved complete recovery within 11 days by comprehensive therapeutic strategies

We present the first case of a huge racemose hemangioma of the bronchial artery (RHBA) with multiple arterial supply, and the clinical findings indicated the possibility of coronary steal phenomenon due to the arterial supply from the right coronary artery (RCA) to the hemangioma.

Most published management strategies of tracheocutaneous fistulas typically focus on surgical approaches. However, in certain scenarios such as patients with respiratory insufficiency or chronic respiratory failure, surgical management poses an unacceptable perioperative risk. This case highlights a non-surgical approach to TCF management that is not well-described in the literature and presents an alternative management option for cohorts of patients in which the risk associated with surgical interventions may be undesirable.

Here we report a case of a patient who was negative on thoracentesis and underwent cryobiopsy from the visceral pleura by thoracoscopy under local anaesthesia. The technique was performed safely and led to a diagnosis.

We report an extremely rare case of cervical thymoma with 99mTcMIBI scintigraphic accumulation associated with myasthenia gravis that was difficult to diagnose and treat.

Osimertinib re-challenge could be an optional treatment for the end-stage EGFR-mutated NSLCs. The combination therapy of the driver EGFR mutation TKI and the NTRK fusion inhibitors could provide clinical benefit and could be considered as a therapeutic option for patients with NTRK fusion being acquired as a resistance mechanism.

Indwelling pleural and peritoneal catheters improve quality of life in patients with malignant pleural effusions and ascites. However, they are associated with catheter-related infections, traditionally managed with systemic antibiotics. We present a patient with peritoneal mesothelioma who developed Staphylococcus aureus peritonitis three weeks after indwelling catheter insertion and successfully treated with intraperitoneal vancomycin directly to the site of infection.

SCHs are benign vascular tumor that occurs in young adults and typically arises in the subcutis of the distal extremities, particularly the hand. So far only two cases of pulmonary SCH were reported in the literature. Our case is instructive by its different clinical (hemoptysis) and radiological presentation (cavitary lesion) compared to the previous two cases.

In our report, we present the case of a career welder who consulted with vocal cord palsy and an atypical anterior mediastinal lesion. An EBUS-TBNA-guided biopsy and a thorough cytological assessment led to an unexpected diagnosis of epithelioid malignant pleural mesothelioma (MPM). A localized anterior mediastinal lesion is an extremely infrequent presentation of MPM that deserves clinical recognition.

This case reports a patient diagnosed with Birt-Hogg-Dubé syndrome (BHDS), a rare disease, with an increased risk of fibrofolliculomas in the skin, multiple lung cysts predisposing to recurrent pneumothorax and increased risk of renal cancer. Its clinical expression is variable, which makes the diagnosis and management difficult.

Tension pneumomediastinum is a rare complication of interstitial pneumonia. This case shows computed tomography findings of the Macklin effect, in which air dissection along the bronchovascular interstitium caused by alveolar rupture leads to pneumomediastinum.

Here we report a rare case of acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) after coronavirus disease 2019 (COVID-19) vaccination. Although, it is difficult to differentiate idiopathic AE from COVID-19 vaccination-induced AE, we suppose that vaccination can trigger AE of IPF characterized by a steroid-responsive episode.
