We describe three cases who presented with haemoptysis, which on further evaluation were diagnosed as isolated tracheobronchial amyloidosis, and a review of literature.

Melioidosis is an emerging disease in India. Mediastinal abscess is rare in melioidosis. We have reported three such cases. Endobronchial ultrasound helped in diagnosis.

We described three patients with complex pleural effusions who received intrapleural fibrinolysis therapy with different bleeding risks.

Thunderstorm asthma had previously been considered unlikely to occur in New Zealand (NZ), given its local weather patterns. Storm events on 2 December 2017 led to increased asthma presentations at Waikato Hospital in Hamilton. Analyses of patient presentations led us to conclude that these presentations were similar to international descriptions of thunderstorm asthma. This is the first time such presentations have been reported in NZ.

Here, we present an extremely rare case of coexistence of lung squamous cell carcinoma with mucosa‐associated lymphoid tissue (MALT) lymphoma presenting as progressive lung ground‐glass nodules.

Tracheal and bronchial varices are rare, especially in children. We report the first presentation of bronchial varices and haemoptysis in a child, six years after a Fontan procedure for tricuspid atresia. She had tortuous mediastinal and transpleural arterial collaterals on imaging and subsequently underwent embolization of these collaterals with haemoptysis settling after this.

Indwelling pleural catheter (IPC) is a useful tool for refractory malignant pleural effusions (MPEs). Its use in benign pleural effusions comes mainly from retrospective studies, case series, and case reports. Lupus effusion is common, causes minimal symptoms, and usually responds to either steroid therapy or immunosuppressants. We describe a 52‐year‐old woman whose first presentation of systemic lupus erythematosus (SLE) was a pleural effusion refractory to steroids and immunosuppressants. She successfully achieved spontaneous pleurodesis with intermittent IPC drainage at three months.

Here, we report a case of non‐severe coronavirus disease 2019 (COVID‐19) complicated by pulmonary embolism (PE), which indicates that the possibility of PE should consistently be considered, even in non‐severe cases of COVID‐19 without any risk of thrombosis.

We describe a 69‐year‐old woman with underlying diffuse large B‐cell lymphoma of the colon 16 years ago in remission, who presented with a new problem of refractory chylothorax. It was successfully treated with continuous positive airway pressure (CPAP) ventilation in tandem with talc pleurodesis.

Here, we report a patient with non‐small cell lung cancer‐not otherwise specified (NSCLC‐NOS) with high PD‐L1 expression and aberrant granulocyte colony‐stimulating factor (G‐CSF) production, in whom monotherapy with the anti‐PD‐1 antibody pembrolizumab was effective as an initial treatment.

Here, we report the case of a 37‐year‐old pregnant Japanese woman with bronchial mucoepidermoid carcinoma, recurrent asthmatic symptoms, and pneumonia that we treated successfully via interventional bronchoscopy and surgery. At one‐year follow‐up, the patient was disease‐free and her baby was growing well.

We report the first case of incomplete metalloptysis linger pneumonia after the wedge resection of organizing pneumonia, with complete recovery by removal of residual clips, where clips from the staple cartridges had been applied on the periphery of the lung migrated and been incompletely expectorated.

We present a rare case of symptomatic thrombocytopaenia associated with nintedanib treatment in a patient with idiopathic pulmonary fibrosis (IPF).

Synchronous triple thymic carcinomas and thymoma have not been reported. The finding of this case report supports the hypothesis of malignant transformation of thymoma to thymic carcinoma.

We describe the surprise finding of haemorrhagic endobronchial casts causing complete ventilation failure in the first patient placed on extracorporeal membrane oxygenation (ECMO) for coronavirus disease 2019 (COVID‐19) in Australia. Removal of casts with international bronchoscopy procedures leads to the restoration of ventilation.

We report a case of large cell carcinoma identified during differential diagnosis of diffuse alveolar haemorrhage in a patient with haemoptysis.

We describe the clinical progress of siblings who initially presented with an undifferentiated paediatric interstitial lung disease at birth which was eventually diagnosed in adulthood as pulmonary surfactant dysfunction due to ATP‐binding cassette subfamily A member 3 (ABCA3) mutations. Clinical deterioration was due to progressive pulmonary hypertension and a moderate decline in forced expiratory volume in 1 sec (FEV₁), rather than progression of the interstitial lung disease.

Solitary fibrous tumour of the pleura (SFTP) is a rare neoplasm. Moreover, cavity formation associated with SFTP is extremely rare. To our knowledge, only one such case has been previously reported.

The incidence of immune checkpoint inhibitor (ICI)‐induced gastritis is relatively rare, compared with colitis, but a massive immunoreaction caused by ICIs can induce severe gastritis. Thus, gastritis should be considered when patients taking ICIs complain of any gastrointestinal symptoms.
