[A case of vesical malacoplakia].

A 44-year-old woman was admitted to our hospital, complaining of terminal hematuria. On cystoscopy four yellow and soft nodular masses were observed in the bladder, one of which had central ulceration. TUR was performed for these masses. Histological examination revealed that they were vesical malacoplakia. The masses consisted of aggregates of macrophages with abundant cytoplasma in which typical Michaelis-Gutmann bodies were demonstrated by light and electron microscopies.
