Fig. 2.

Microscopic photographs of the resected tissues are shown. Hyphae of Candida albicans were observed among degenerated epithelial cells (upper left panel; H&E, hematoxylin and eosin stain). Nuclei of the background urinary bladder epithelial cells were enlarged and irregular; however, structural atypia did not reach the degree seen in cancer cells (upper right panel). Moreover, CK20-positivity was limited in the cytoplasm of umbrella cells (lower left panel) and p53-positivity was weak in the nuclei of basal cells (lower right panel).
