A 49-year-old male was referred to our hospital with the chief complaint of gross hematuria. We performed cystoscopy, and found a solid tumor at the dome of the bladder. Sagittal magnetic resonance imaging revealed an extravesical tumor at the position of the urachus. Transurethral resection of bladder tumor was performed. A solid tumor at the dome and two papillary tumors at the right lateral region of the bladder were observed. A pathological examination revealed adenocarcinoma from the solid tumor and urothelial carcinoma from the papillary tumors. Under a diagnosis of double cancer, adenocarcinoma of the urachus and urothelial carcinoma of bladder, we performed a total cystectomy, neobladder and total resection of the urachus.
