Aspergillus Bronchitis at Localised Mucus Plug in an Immunocompetent Patient. [PDF]

Respirol Case Rep
We report a case of Aspergillus bronchitis in an immunocompetent 55‐year‐old woman with a mucus plug at the site of localised bronchiectasis. The mucus plug gradually enlarged over 9 years, when the patient exhibited submissive haemoptysis. Bronchial artery embolization, followed by partial lung resection was performed.

Clinical significance of chronic pulmonary aspergillosis in lung cancer patients undergoing anticancer drug therapy. [PDF]

Thorac Cancer
We investigated the clinical impact of chronic pulmonary aspergillosis (CPA) in patients with lung cancer (LC) receiving anticancer drug treatment in a real‐world setting. The cause of death in LC patients with concomitant CPA who received anticancer drug treatments and effective antifungal treatment was LC progression.
