BORDERLINE BRENNER TUMOR Figure 5-13 BORDERLINE BRENNER TUMOR This borderline Brenner tumor resembles transitional-like growth of high grade serous carcinoma at low-power (left), but at higher magnification it has bland uniform nuclei, unlike those of high-grade serous carcinoma.

COMPOSITE BRENNER AND MUCINOUS TUMORS Figure 9-6 COMPOSITE BRENNER AND MUCINOUS TUMORS A: Composite Brenner tumor with mucinous cystadenoma. B: High molecular weight keratin antibody decorates squamotransitional cells, but not the mucinous cystadenoma. C: Stromal-invasive mucinous carcinoma ari...

MALIGNANT BRENNER TUMOR Figure 9-11 MALIGNANT BRENNER TUMOR Left: Irregularly shaped nests of malignant squamoid cells in desmoplastic stroma is typical. A benign or borderline Brenner component should be present (not shown) to confirm Brenner lineage. Otherwise, squamous cell carcinoma is a diag...

BORDERLINE BRENNER TUMOR Figure 9-8 BORDERLINE BRENNER TUMOR A large cystic space with exophytic papillae is situated adjacent to a benign Brenner tumor (left). Complicated, inverted papillae of a borderline Brenner tumor (right). More about this image found in BORDERLINE BRENNER TUMOR A large cystic space with exophytic papillae is s...

BRENNER TUMOR WITH CROWDED NESTS Figure 9-7 BRENNER TUMOR WITH CROWDED NESTS Although the nests are closely spaced, they do not merge and do not form cystic spaces containing exophytic papillae (features of border line Brenner tumor). Low nuclear grade and absence of a stromal reaction exclude ma... More about this image found in BRENNER TUMOR WITH CROWDED NESTS Although the nests are closely spaced, th...

BORDERLINE BRENNER TUMOR WITH INTRAEPITHELIAL CARCINOMA AND MICROINVASION Figure 9-10 BORDERLINE BRENNER TUMOR WITH INTRAEPITHELIAL CARCINOMA AND MICROINVASION A,B: The general architecture of borderline Brenner tumor is retained, but tumor cells are cytologically malignant. No stromal invasion i... More about this image found in BORDERLINE BRENNER TUMOR WITH INTRAEPITHELIAL CARCINOMA AND MICROINVASION ...

BRENNER TUMOR Figure 9-4 BRENNER TUMOR Large nests with lumen formation (left) are seen as well as peripheral palisading of transitional cells (right). More about this image found in BRENNER TUMOR Large nests with lumen formation (left) are seen as well as ...

BENIGN BRENNER TUMOR Figure 9-2 BENIGN BRENNER TUMOR The cut surface of this 6-cm tumor is predominantly solid, with small cystic spaces present (arrows). More about this image found in BENIGN BRENNER TUMOR The cut surface of this 6-cm tumor is predominantly s...

BRENNER TUMOR Figure 9-3 BRENNER TUMOR Left: Low-power magnification shows an adenofibromatous growth pattern, small basaloid nests, some with central lumens, and dystrophic stromal calcification. Right: Nests of transitional cells lacking atypia are in a fibromatous background. More about this image found in BRENNER TUMOR Left: Low-power magnification shows an adenofibromatous grow...

BRENNER TUMOR WITH EXTENSIVE MUCINOUS DIFFERENTIATION Figure 9-5 BRENNER TUMOR WITH EXTENSIVE MUCINOUS DIFFERENTIATION A–C: The nests contain two cell types: basal squamotransitional cells and luminal mucinous cells.

BORDERLINE BRENNER TUMOR Figure 9-9 BORDERLINE BRENNER TUMOR Blunt intracystic papillae (A,B) and bland nuclear features with maturation from base to lumen (B,C) are seen. These features are similar to noninvasive low-grade papillary urothelial carcinoma or urothelial papillary neoplasm of low ma...
