The results of hematoxylin-eosin staining: (A) Microscopic pathological nuclear fission image, keratin pearls and intercellular bridges are present in many cases of well-differentiated carcinoma. No components of transitional epithelial carcinoma were seen. Immunohistochemically: the cell membranes and cytoplasm were positive for (B) CK5/6. The nucleus were positive for (C) p40 and (D) p63.

H&E staining ( Figure 1 ) microscopically showed heterogeneous proliferating squamous epithelial cells with infiltrative growth. Immunohistochemically (IHC), the tumor cells were positive for CK5/6 ( Figure 1B ), P40 ( Figure 1C ), and P63 ( Figure 1D ).
Cystoscopy showed good bladder filling and no new organisms were seen. The left ureteral opening was higher than the right, and scarring changes were seen after surgery.

A repeat cystoscopy ( Figure 2 ) and pelvic CT ( Figure 3 ) showed no signs of recurrence or metastasis.
Pelvic CT did not show tumor recurrence and metastasis.
