A 57\u2010year\u2010old man presented with fever and dyspnoea and was admitted to our hospital. Chest computed tomography revealed a new left lower lung infiltrate, tumour progression in the right upper lung region, metastases to lymph nodes and pleural effusion. The urinary antigen test for <jats:italic>Legionella<\/jats:italic> was positive. The patient's oxygen requirement increased on the day of admission, and he died the day after hospitalization. Legionnaires' disease may manifest with an acute presentation, and patients in Japan with physical risk factors for this disease could get infected despite the absence of environmental risk factors. Early treatment for suspected Legionnaire's disease should be considered.<\/jats:p>","DOI":"10.1002\/rcr2.850","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T05:04:04Z","timestamp":1633842244000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["<i>Legionella
