Computed tomography suggested bladder cancer with pulmonary metastases. However, due to the extent of the bladder tumor, complete resection was not feasible, and only a limited transurethral resection was performed for diagnostic purposes. Pathological examination revealed bladder amyloid \u03bb amyloidosis. Remarkably, five months post\u2010surgery, both bladder and pulmonary lesions resolved spontaneously. No recurrence was observed during six years of follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This case highlights a rare instance of spontaneous remission in bladder amyloidosis. However, such occurrences were exceedingly uncommon, and systemic amyloidosis can progress to a life\u2010threatening condition. Therefore, careful follow\u2010up, surgical removal, or systemic therapy is essential for bladder amyloidosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/iju5.70123","type":"journal-article","created":{"date-parts":[[2025,12,28]],"date-time":"2025-12-28T18:34:02Z","timestamp":1766946842000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Bladder Amyloidosis With Pulmonary Lesions: A Case of Spontaneous Remission After Transurethral Resection"],"prefix":"10.1002","volume":"9","author":[{"given":"Suguru","family":"Ito","sequence":"first","affiliation":[{"name":"Department of Urology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"},{"name":"Department of Urology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuma","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Hematology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Hematology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"},{"name":"Department of Hematology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunihiko","family":"Maeda","sequence":"additional","affiliation":[{"name":"Department of Pathology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinta","family":"Suenaga","sequence":"additional","affiliation":[{"name":"Department of Urology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"},{"name":"Department of Urology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidenori","family":"Kanno","sequence":"additional","affiliation":[{"name":"Department of Urology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sadanobu","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Urology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigemitsu","family":"Horie","sequence":"additional","affiliation":[{"name":"Department of Urology Okitama General Hospital  Kawanishi, Higashiokitama Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sei","family":"Naito","sequence":"additional","affiliation":[{"name":"Department of Urology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norihiko","family":"Tsuchiya","sequence":"additional","affiliation":[{"name":"Department of Urology Yamagata University Faculty of Medicine  Yamagata City Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,28]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1159\/000506617"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.14797\/mdcj\u20108\u20103\u20103"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rdc.2013.02.012"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1155\/ah\/7280805"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11926\u2010024\u201001147\u20108"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hfc.2024.03.007"},{"key":"e_1_2_9_8_1","first-page":"8868","article-title":"Primary Amyloidosis of the Bladder;
