title: [Recurrence of bladder cancer in fossa navicularis 17 months after cystourethrectomy: a case report].
abstract: We report a case of bladder cancer recurrence in fossa navicularis of urethra 17 months after cystourethrectomy for bladder cancer. A 75-year-old man had undergone cystourethrectomy preserving between fossa navicularis and external meatus, and ileal conduit urinary diversion for advanced bladder cancer on June 24, 2002. Histopathological findings showed urothelial carcinoma, G2>G3, pT1N0. The patient had been followed regularly for 17 months without evidence of recurrence until he suffered the onset of hemorrhagic urethral discharge. Endoscopic examination of the residual urethra showed multiple, papillary sessile tumors which almost filled the fossa navicularis. He was admitted to our hospital on December 15, 2003. The urethral wash cytology revealed urothelial carcinoma. Since computed tomography, magnetic resonance imaging, and bone scintigraphy showed no evidence of lymph node and distant metastasis, partial penectomy was performed. Histopathological findings showed urothelial carcinoma pTa, G2>G3, which was identical to primary tumor. Tumor had not invaded the corpus cavernosum. Careful follow-up of the patients with preservation of fossa navicularis is important.
