[Pseudo-tumoral colic metaplasia of the urinary bladder]

Colic metaplasia of the urinary bladder is a rare disease, secondary to a chronic irritative factor. In its minor form, it has the same clinical features as simple cystitis, but its major pseudoneoplastic form may be mistaken for bladder tumor. The diagnosis is essentially histological. Treatment is based on eradication of the irritative factor and of the resection of pseudoneoplastic form. Surgery is performed in the case of complications of this disease. The clinical course is unclear, requiring long-term surveillance. We report one case of colic-type glandular metaplasia of the urinary bladder in a 50 years-old patient. The clinical symptomatology was dominated by hematuria and pollakuria. A bladder neoplasm was highly suspected in ultrasound and endoscopic findings. The patient underwent a transurethral resection of the bladder tumor. Histological examination of of resection shavings revealed a colic-type glandular metaplasia.
