Primary squamous cell carcinoma of the urethral diverticulum mimicking prostate cancer: Case report and review of the literature
Keywords:urethral diverticular cancer, squamous cell carcinoma, primary urethral tumor, urethral diverticulum
AbstractPrimary urethral carcinomas are uncommon, with urothelial carcinoma as the most common subtype. Urethral diverticulum is also rarely seen in men. A 44-year-old male presented with voiding symptoms. Abdominoperineal resection, prostatectomy, bladder neck excision, and proximal urethral excision were performed. A pathological examination revealed a well-differentiated squamous cell carcinoma (SCC) located inside an urethral diverticulum. We report this unusual case because primary SCC of the male urethral diverticulum is extremely rare. To our knowledge, our patient is only the second reported case.
