Background: Bladder adenocarcinoma (AC) is a rare histological variant and research on the best ways to treat it is scant.
Clinical Case: We present the case of a 70-year-old woman who has had hematuria for the past month with no history of serious illness. She visited a urologist, who performed a cystoscopy on her as a result. A urinary bladder adenocarcinoma was discovered in a biopsy. Complete investigations revealed no metastasis. The patient was considered for a partial cystectomy, according to the results of the MRI. She underwent the surgery, which was followed by concurrent chemo-radiotherapy. She underwent multiple reevaluations, and her case was stable after about a year of follow-up.
Conclusions: With the best surgical outcomes, the choice to perform a partial cystectomy was appropriate given the tumor's location. However, a lengthy follow-up is required.
