Figure 03-01. Normal Voided Urine. Most benign voided urine samples show a mixture of urothelial cells and squamous cells. In voided urine, most of the urothelial cells are of “intermediate” type, with an oval or pyramidal shape; they resemble the parabasal cells of the cervix.
120
Figure 03-02. Cytoplasmic Inclusions (Melamed-Wolinska Bodies). Degenerating urothelial cells frequently have round, red (or sometimes green) cytoplasmic inclusions of varying sizes. A normal columnar-shaped urothelial cell is also present.
121
Figure 03-03. Umbrella Cells (Ureteral Washing). These are the largest urothelial cells. They cover the surface of the urothelium and are often binucleated or multinucleated. Normal columnar urothelial cells are also present.
122
Figure 03-04. Benign Urothelial Cells Can Have a Folded and Flattened Nucleus (Catheterized Specimen). The nucleus of benign urothelial cells is not always perfectly round. Some indentation and deformation, including straight edges that give the cells a flat geometric contour, are common. They are recognized as benign because of their normal nuclear-to-cytoplasmic ratio and normochromasia.
123
Figure 03-05. Basal Urothelial Cells (Catheterized Specimen). Basal urothelial cells are rare in voided urine but common in catheterized specimens and usually tightly clustered.
124
Figure 03-06. Seminal Vesicle or Prostatic Epithelial Cells (Voided Urine). These cells are recognized because of their golden-brown pigment. Sometimes they are less well preserved than seen here.
125
Figure 03-07A. Ileal Loop Specimen. (A) Most of the cells in an ileal loop specimen are degenerated intestinal cells and look very much like macrophages. (B) Degenerated intestinal cells can have Melamed-Wolinska bodies (arrows) just like urothelial cells. Lubricant is present (arrowheads).

127
Figure 03-08A. Polyomavirus Infection. (A) In some cases, the nucleus is filled with and expanded by a glassy basophilic inclusion. Nuclear chromatin is pushed to the nuclear membrane, giving it a thickened and beaded appearance. (B) Some of the affected cells have a characteristic tear-drop or comet shape. (C) The inclusions do not always completely fill the nucleus, leaving clumps and threads of visible chromatin. Note the marked nuclear enlargement by comparison with the nuclei of normal squamous cells. (D) Some chromatin texture is visible. Note how round the nucleus is.

Figure 03-09A. Condyloma Acuminatum of Bladder (Catheterized Urine). (A) The sample contains koilocytes. (B) A bladder biopsy confirmed the diagnosis (hematoxylin and eosin stain).
132
Figure 03-10. Chemotherapy Effect (Catheterized Urine). This enormous multinucleated cell has a normal nuclear-to-cytoplasmic ratio. Note that, where the nuclei are not overlapped, one can tell that the chromatin is finely textured. Coarse vacuolization is typical of benign reactive changes, including chemotherapy and radiation effect.
133
Figure 03-11. Benign Stone Atypia (Voided Urine). In some patients with stones, urothelial cells are markedly abnormal, with hyperchromatic and angulated nuclei. A distinction from urothelial carcinoma in such cases is impossible. The patient’s age (27 years old) was the only clue that these cells might not be malignant. A subsequent computed tomography scan demonstrated bilateral renal stones. The exceptional atypia of these cells prompted a suspicious interpretation. Cystoscopic evaluation of the bladder, kidneys, and ureters was normal.
134
Figure 03-12A. Nephrogenic Adenoma (Catheterized Urine). (A) The cells are smaller than intermediate urothelial cells, with granular cytoplasm and a round nucleus. (B) A bladder biopsy demonstrates the resemblance to renal tubular epithelium (hematoxylin and eosin stain). The cells are positive for PAX8 (Inset).
135
Figure 03-13. High-Grade Urothelial Carcinoma (Catheterized Urine). Numerous isolated malignant cells have an enlarged nucleus, coarsely textured chromatin, and a markedly increased nuclear-to-cytoplasmic ratio. An occasional cell has a mucin vacuole, which is not uncommon.
136
Figure 03-14. High-Grade Urothelial Carcinoma With Jet-Black Chromatin (Ileal Loop Specimen). The cells have markedly irregular nuclear outlines, including nuclear points, but in many places the chromatin is smooth and black rather than coarsely granular.
137
Figure 03-15. High-Grade Urothelial Carcinoma With Straight and Curved Nuclei (Voided Urine). The nuclei are elongate and dark, with either a straight or curved edge that imparts a sickle or crescent-moon shape.
138
Figure 03-16A. High-Grade Urothelial Carcinoma With Umbrella-Cell Features (Catheterized Urines). (A) This malignant cell is large, with a markedly enlarged nucleus and prominent nucleoli. In most examples, like this one, the nuclear-to-cytoplasmic ratio is elevated, and there are usually far too many such cells for them to be normal umbrella cells, yet the nuclear membrane is smooth and regular, and the chromatin is finely textured. (B) Some of these “umbrella-cell” variants have obviously malignant nuclei, even though the nuclear-to-cytoplasmic ratio is only mildly increased.

140
Figure 03-17A. High-Grade Urothelial Carcinoma With Pale Chromatin (Catheterized Urine). (A) The malignant cells have markedly enlarged nuclei but relatively pale chromatin, and there is a mitosis (arrow). (B) The marked nuclear enlargement can be appreciated by comparing to adjacent normal urothelial cells on the right.

(B) The marked nuclear enlargement can be appreciated by comparing to adjacent normal urothelial cells on the right.
142
Figure 03-18. High-Grade Urothelial Carcinoma With Smooth Round Nuclei and Granular Chromatin. The nuclear-to-cytoplasmic ratio is very high, and chromatin is coarse and clumpy.
143
Figure 03-19. High-Grade Urothelial Carcinoma With Smooth Round Nuclei and Prominent Nucleoli. The nuclear-to-cytoplasmic ratio is increased, and nucleoli are prominent.
144
Figure 03-20. High-Grade Urothelial Carcinoma With Small Nuclei (Ileal Loop). The nuclear-to-cytoplasmic ratio is very high, the nuclear outline is irregular, and the cells may have one or more nucleoli, but the chromatin is not coarse and clumpy. These cells are smaller than reactive urothelial cells.
145
Figure 03-21. High-Grade Urothelial Carcinoma With Extensive Degeneration (Voided Urine). The sharp angularity (“points”) of degenerated cells helps to identify them as malignant.
146
Figure 03-22A. Urothelial Carcinoma Variants. (A) Some of the malignant cells show squamous differentiation, manifested by cytoplasmic orangeophilia. (B) Some urothelial carcinomas have foci of adenocarcinoma.

148
Figure 03-23. Suspicious for Urothelial Carcinoma. The suspicious cells are few in number and poorly preserved. The irregularity of the nuclear membrane is more typical of malignancy than polyomavirus effect.
149
Figure 03-24. Clear Cell Adenocarcinoma. The cells are large, with abundant clear cytoplasm, large nuclei, and large nucleoli.
150
Figure 03-25. Prostatic Carcinoma (Voided Urine). Many prostate cancers are impossible to distinguish from urothelial carcinoma. Inset, Immunohistochemistry for prostatic markers can be helpful (cell block, prostate specific antigen).
151
Figure 03-26A. Metastatic Colon Cancer to the Bladder Neck (Voided Urine). (A) The majority of the malignant cells are round, with dark, angulated nuclei. Distinction from urothelial carcinoma is not possible by cytomorphology. (B) A cell block preparation contains occasional degenerated malignant cells. (Inset) the malignant cells show nuclear reactivity for CDX-2, commonly seen in colon cancers and usually absent in urothelial cancers. The malignant cells were also positive for cytokeratin 20 and negative for cytokeratin 7, the typical keratin profile of colon cancer.
