Background: We report very rare subtype of prostate cancer, prostate ductal adenocarcinoma, found in the urinary sediment. Case: The patient was a man in his 80s. He had a history of low-grade urothelial carcinoma (LGUC) 5 years ago and is continuing follow-up. Urinalysis showed atypical cells. Subsequent examination revealed that the atypical cells were prostate ductal adenocarcinoma cells. Conclusion: Urinary sediment examination revealed a rare case of adenocarcinoma. In this case, LGUC could not be ruled out, and it was difficult to distinguish prostate ductal adenocarcinoma and LGUC. However, we were able to report it as an unusual finding and proceeded to a closer examination. It is important to improve the accuracy of testing by carefully reviewing the test results.
