We report the case of a 68-year-old man previously treated for high-grade pT1 urothelial carcinoma with transurethral resection and intravesical Bacillus Calmette\u2013Gu\u00e9rin therapy, who subsequently developed recurrent gross hematuria and bladder wall thickening suspicious for tumor recurrence. Histopathological examination revealed marked eosinophilic infiltration without evidence of malignancy, confirming eosinophilic cystitis. Bacillus Calmette\u2013Gu\u00e9rin therapy was discontinued and conservative treatment led to complete clinical resolution, with no recurrence detected during follow-up. This case emphasizes the importance of histological confirmation before escalating oncological treatment in patients with suspected bladder cancer recurrence.<\/jats:p>","DOI":"10.1093\/jscr\/rjag855","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T11:18:57Z","timestamp":1789384737000},"source":"Crossref","is-referenced-by-count":0,"title":["A
