This article describes a rare case of primary urothelial carcinoma in the prostate (UCP) and reviews the literature. The case involves a 67-year-old widowed male with symptoms of frequent and urgent dysuria. After imaging and biopsy, the patient was diagnosed with prostatic high-grade urothelial carcinoma and underwent radical prostatectomy. Four months after surgery, further examinations revealed thickening of the bladder wall and the presence of malignant tumor.
Background: Primary urothelial carcinoma in the prostate (UCP) is extremely rare and occurs most frequently in the bladder. There are only dozens of primary cases reported in the literature. Here, we describe a rare case of primary UCP and review the literature.Case presentation: A 67-year-old widowed male, was referred to our hospital due to the frequency, and urgency of dysuria. Magnetic resonance imaging (MRI) examination revealed prostate size was about 57 mm x 50 mm x 54 mm, increased prostatic transitional zone, and surrounding of prostatic duct indicate bar isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 3); posterior of peripheral zone indicate patchy isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 5). Subsequently, the patient underwent a transrectal prostate biopsy. Histopathological and immunohistochemical (IHC) assessments showed prostatic high-grade urothelial carcinoma with benign prostatic hyperplasia. Finally, the patient underwent laparoscopic radical prostatectomy. Four months after surgery, CT plain and enhanced scan revealed thickening of the bladder wall. On further workup, cystoscopy revealed lymphoid follicular changes in the cut edge of the radical prostatectomy, and cystoscopic biopsies showed the malignant tumor.Conclusions: Prostatic urothelial carcinoma should always be considered if the patient with severe lower urinary tract symptoms or hematuria, PSA, and digital rectal examination without abnormalities, without a personal history of urothelial cancer, but contrast-enhanced MRI showed the lesion located in the prostate. As of right now, radical surgical resections remain the most effective treatment. The effectiveness of neoadjuvant or adjuvant chemotherapy is still controversial.
