Abstract
|
|
|
Primary carcinoma arising in the diverticular wall of the urinary bladder is the most serious complication. The clinical importance is that the carcinoma is difficult to diagnose early, widespread at diagnosis and has poor prognosis. Recently, vigilant studies including bladder mapping reveal premalignant changes and carcinoma in situ adjacent to carcinoma and suggest these premalignant changes evolve to flank carcinoma. For early detection and improving the prognosis, be required through cystoscopic examination including diverticular wall and multiple punch biopsies as well as consecutive urine cytologic examination.
Author report two cases of primary carcinoma arising in bladder diverticulum. One revealed carcinoma in situ accompanied with adjacent atypical hyperplasia in diverticula mucosa incidentally found at the pathologic examination on the divertiuclectomy specimen. The other case showed invasive transitional cell carcinoma(Grade IV, Stage D) of diverticulum.
The two cases described suggest that vesical diverticulum should be removed into to with a good amount of surrounding bladder wall.
