Abstract
Background: Prostate ductal adenocarcinoma, a rare histology observed in 0.4-0.8% of all prostate cancers, is treated similarly to acinar adenocarcinoma but tends to have a higher likelihood of metastasis, recurrence, and poorer prognosis.
Case presentation: A 73-year-old Asian-Japanese male presented with gross hematuria, with investigations revealing a prostate ductal adenocarcinoma. Subsequent radical prostatectomy indicated a Gleason score of 8 with no lymph node metastasis. Despite initial prostate-specific antigen level reductions post-prostatectomy and salvage radiation therapy due to recurring elevated prostate-specific antigen levels, no recurrence was evident until 13 years later. A tumor in the anterior urethra was identified as metastasis of his prostate ductal adenocarcinoma.
Conclusion: This report presents an uncommon case of prostate ductal adenocarcinoma exhibiting a late recurrence in the anterior urethra 13 years post-radical prostatectomy.
期刊介绍：
JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
