Abstract

A 15-month-old infant who had a history of dysuria, pyuria, fever and suprapubic tumor mass for a period of days was admitted in June in 1966. The bladder was opened suprapubically. It was filled with grape-like, grey, gelatinous masses. Microscopically the surface epithelium has undergone squamous metaplastic, and neoplastic tissue reveals both myxomatous and fibromatous patterns. In the latter a few tumor giant cells with one or more nuclei are very occasionally seen. In a few areas tumor cells simulate epitheloid arrangement. No mitotic figures. No striation was found on phosphotungustic stain.
