Metastatic hepatocellular carcinoma (HCC) can involve the lung parenchyma. However, predominant thoracic lymphadenopathy involvement is less described and there are multiple alternative malignant and non-malignant causes of a similar appearance. Accurate tissue diagnosis is important to determine appropriate management and prognostication. Here, we report two cases of metastatic HCC recurrence causing large thoracic lymphadenopathy, diagnosed adequately and safely by linear endobronchial ultrasound (EBUS) transbronchial needle aspiration.The diagnosis of pneumopericardium can be challenging, as the symptoms are sometimes non-specific and can mimic those of other diseases. Especially, focal pneumopericardium presenting with regional ST-segment elevation on the electrocardiogram can be difficult to diagnose. Here, we present the case of a patient with pneumopericardium secondary to oesophageal cancer that was first diagnosed with community-acquired pneumonia and subsequently classified with acute coronary syndrome after an episode of cardiac arrest. The most prominent indication initially observed in this case was the history of oesophageal cancer and the presence of radiolucent areas in the heart under pleural effusion. When an unknown origin collapse develops in patients with oesophageal cancer, pneumopericardium should always be excluded, especially in cases where the cardiogenic shock is strongly suspected.A case of tracheobronchopathia osteochondroplastica (TO) was diagnosed in a 53-year-old man, who presented with prolonged cough and recurrent respiratory tract infection. Bronchoscopy revealed exostosis over the anterolateral wall of trachea and main bronchi sparing the posterior membranous wall. The endobronchial biopsy subsequently revealed ossification of the cartilage. To date, the aetiology of this condition remains unknown, and treatment is mainly symptomatic, emphasizing on timely management of recurrent respiratory infections. Bronchoscopy or surgical intervention is usually reserved for symptomatic patients with severe airway narrowing and airflow obstruction.Pulmonary lymphomatoid granulomatosis (PLG) is a rare multisystem Epstein-Barr virus (EBV)-associated lymphoproliferative disorder. Exact incidence is unknown and, with its variable clinical presentation, making an accurate diagnosis of PLG can be difficult. We present two distinct cases at our tertiary centre that underline PLG's non-specific clinical presentations. This resulted in the failure of recognizing PLG early with consequently progressive fatal outcomes. The rationale is to enlighten us concisely the knowledge surrounding PLG and consider it as a potential differential diagnosis, particularly in those immunosuppressed patients with radiological evidence of worsening pulmonary infiltrates not responding to customary treatment for common diagnoses. Having a high degree of suspicion for PLG in the right setting and pursuing lung biopsy early if appropriate for histopathology examination would be justified. This is essential to correctly diagnose PLG up-front and subsequently utilize best management approach for a better survival and mortality risk outlook.Pleural effusion secondary to a pancreatico-pleural fistula is a very rare presentation in children, with limited reports in the literature. We describe two differing presentations of pleural effusions resulting from chronic pancreatitis (CP) with successful resolution of the pleural effusion. These cases highlight the need for consideration of this rare paediatric diagnosis, and the variety of investigations, management strategies, and complications that can occur in the setting of CP in children.Granulation tissue formation is one of the late complications of tracheostomy. It can cause stomal stenosis secondary to chondritis because of disproportionate excision of the anterior cartilage. Clinicians should carefully determine the incision point, which is typically located half way between the cricoid cartilage and the sternal notch.Amyloidosis is an uncommon multisystem disease that can affect many organs. However, interstitial lung involvement is very rare. A 68-year-old man presented with long-standing dyspnoea and productive cough. After extensive investigation, including two non-diagnostic bronchoscopies, a surgical lung biopsy demonstrated pulmonary amyloidosis. A bone marrow biopsy confirmed multiple myeloma.

Here, we report our experience of a successful endobronchial occlusion using endobronchial Watanabe spigots (EWSs) for empyema with broncho-pleural fistula secondary to COVID-19 pneumonia. A 62-year-old man was diagnosed with COVID-19 and progressed to empyema with broncho-pleural fistula. Computed tomography (CT) imaging showed cyst formation and the right B5b was presumed to be a branch dependent on the cyst. The effusion and air in the pleural cavity were well drained, although the air leak persisted. Endobronchial occlusion was performed for right B5a and B5b using 7- and 5-mm EWSs (Novatech, France), respectively, and the air leak ceased. This is the first report of successful treatment of empyema with bronchial fistula with endobronchial occlusion. Air leak secondary to COVID-19 pneumonia with a limited number of air cysts may be a good indication for endobronchial occlusion.Rare cases of co-existing sarcoidosis and carcinoid tumour have been previously reported in the literature. Both diseases may have vague and overlapping clinical presentations that can lead to delayed or missed diagnosis. To avoid this diagnostic pitfall, we discuss and compare the clinical presentations of all reported cases in the literature including our case. We also provide hypothesis to explain the relationship between the two diseases.Two male smokers developed small-cell lung cancer (SCLC) as the second primary malignancy (SPM) in the irradiated field after concurrent chemoradiotherapy for locally advanced cancer, which could also be considered as a radiation-induced tumour. A 70-year-old man received cisplatin and S-1 and irradiation at 60 Gy for lung adenocarcinoma eight years previously and an 81-year-old man cisplatin and 5-fluorouracil and at irradiation 60 Gy for oesophageal cancer five years previously. They sequentially received chemotherapy for SCLC, the effects of which were limited, and a refractory course was noted. Chemoradiotherapy is an effective treatment strategy for locally advanced cancer but may be relevant to the onset of SCLC as SPM.
