Hamartoma of the bladder is quite a rare entity which is composed of a disorderly admixture of mature cellular elements normally present in the urinary bladder. There is a great controversy regarding the pathogenesis of this lesion. Whether it is a true hamartomatous lesion or metaplastic lesion developed secondary to the inflammatory process. Similar or identical lesions has often been given by other names such as florid examples of cystitis glandularis. We prefer to cell florid examples of cystitis glandularis rather than hamartoma when it was occurred in an old age higher then 50th decade. Here we report a case of hamartoma of the urinary bladder in 44 years old man. Cystoscopic examination revealed a papillary polypoid mass which was attached to the fundus of bladder by long stalk. The mass measured 1.5 cm in greatest diameter. It was composed of epithelial nests resembling von Brunn's nest, cystitis glandularis or cystitis cystica dispersed in a stroma rich in smooth muscle and fibrous tissue.
