Abstract
This article provides information on the pathogistology of bladder papilloma.
According to the morphological histotopographical structure of the bladder papilloma studied
by us, it was observed that the composition of the stroma and the number of layers of the
covering multi-layered squamous epithelium, the level of development, and the occurrence
of pathological changes are different. In a papilloma with an angiomatous stroma, the
connective tissue consisting of blood vessels of various sizes appears to be relatively wide
and multi-branched papillomas, and the surface epithelium is elongated and vertically
located.
