[Primary carcinoma in diverticulum of the bladder: a report of three cases].
The first case was in a 48-year-old man admitted with a chief complaint of macroscopic hematuria and sense of residual urine. A tumor in the diverticulum of the bladder was detected by cystoscopy, computed tomography (CT) and magnetic resonance imaging (MRI). We made the diagnosis of an invasive tumor in the diverticulum of the bladder. Total cystourethrectomy and ileal conduit diversion was performed. Histopathological finding was transitional cell carcinoma including squamous cell carcinoma. Adjuvant chemotherapy was performed. No recurrence and metastasis has been recognized for 12 months. The second case was a 56-year-old man having an intradiverticular tumor diagnosed by cystoscopy, CT, and MRI. Total cystectomy and ileal conduit diversion was performed. Histopathological findings was squamous cell carcinoma. No recurrence has been recognized for 8 months. The last case was an 81-year-old man. The patient had the complication of a primary progressive squamous cell carcinoma of the skin. Transurethral resection of diverticular tumor was performed under the diagnosis of superficial tumor. Histopathological findings revealed transitional cell carcinoma. One hundred and sixty one cases of tumor in the diverticulum of the bladder were reviewed. Importance of aggressive treatment including total cystectomy was emphasized.
