ABSTRACT
Bladder reconstruction using bowel segments, especially the ileum, has become a realistic option for urinary diversion. There is only one prior case of squamous cell carcinoma of the ileal neobladder that has been reported in the clinical literature. Here we report a patient with a spectrum of squamous cell lesions, including squamous cell carcinoma, sarcomatoid carcinoma, squamous papilloma and squamous metaplasia that developed in the ileal neobladder. A 46-year-old woman underwent a hysterectomy, cystectomy and ileocystoplasty for tuberculosis 25 years previously complained of urinary frequency and gross hematuria for one week. A pelvic CT revealed a 6.3 cm mass in the neobladder. The histopathological examination showed an 11x8 cm polypoid fragile mass with a microscopically well-differentiated squamous cell carcinoma, squamous papilloma and non-tumor squamous metaplasia.
