a Cytological features of a case NHGUC demonstrated benign intermediate urothelial cells. These cells exhibited round-oval, centrally located nuclei, smooth nuclear membrane, evenly distributed fine chromatin, and low N/C ratio (Papanicolaou stain, ×400). b Histology of the subsequent surgical specimen showed polypoid urothelial mucosa, edematous stroma, and chronic inflammation in laminar propria. The pathologic diagnosis in the case pictured was polypoid cystitis (H&E stain, ×100).
