We report a case of IgG4\u2010related disease mimicking lung cancer with pleural dissemination. A 76\u2010year\u2010old male non\u2010smoker was admitted to our hospital because of chest X\u2010ray abnormality. Chest computed tomography scan showed a lung nodule measuring 26\u2009\u00d7\u200914\u2009mm with tiny nodules on the adjacent pleural surface. Wedge resection by video\u2010assisted thoracoscopic surgery (VATS) was performed to aid diagnosis. Pathological findings of the nodule consisted of lymphoid follicular hyperplasia with lymphoplasmacytic infiltrate, fibrosis, and obstructive vasculitis. Focal and scattered thickening of the pleura with lymphoplasmacytic infiltrate was also observed. The IgG4\/IgG ratio in the most prominent area exceeded 80%. Thus, we made a diagnosis of IgG4\u2010related lung and pleural disease. To our knowledge, there has been no report of IgG4\u2010related lung disease mimicking lung cancer with pleural dissemination.<\/jats:p>","DOI":"10.1002\/rcr2.550","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T07:07:22Z","timestamp":1583824042000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["IgG4\u2010related
