URINARY BLADDER PARAGANGLIOMA Figure 9-18 URINARY BLADDER PARAGANGLIOMA This paraganglioma shows extensive superficial growth beneath the mucosa. The tumor is a potential mimic of urothelial carcinoma because of its growth pattern and pale eosinophilic to clear cytoplasm.

URINARY BLADDER PARAGANGLIOMA Figure 9-35 URINARY BLADDER PARAGANGLIOMA A: This extensively invasive urinary bladder paraganglioma deep within the bladder wall is a potential mimic of prostatic or urothelial carcinoma. B: Diffuse expression of tyrosine hydroxylase confirms the identity More about this image found in URINARY BLADDER PARAGANGLIOMA A: This extensively invasive urinary bladder...

METASTASIS BY RETROGRADE LYMPHATIC SPREAD Figure 52-2 METASTASIS BY RETROGRADE LYMPHATIC SPREAD Left: Metastatic high-grade urothelial carcinoma forms a microscopic metastasis that cannot be seen grossly, but the intense fibrinous pericarditis is a direct consequence of the lymphatic involvement More about this image found in METASTASIS BY RETROGRADE LYMPHATIC SPREAD Left: Metastatic high-grade urot...

OVARIAN SURFACE IMPLANTATION OF HIGH-GRADE UROTHELIAL CARCINOMA Figure 9-13 OVARIAN SURFACE IMPLANTATION OF HIGH-GRADE UROTHELIAL CARCINOMA The patient had an ipsilateral high-grade noninvasive urothelial carcinoma of ureter. No Brenner components are present. More about this image found in OVARIAN SURFACE IMPLANTATION OF HIGH-GRADE UROTHELIAL CARCINOMA The patien...

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 More about this image found in BORDERLINE BRENNER TUMOR Blunt intracystic papillae (A,B) and bland nuclea...

SECONDARY PAGET DISEASE OF UROTHELIAL ORIGIN Figure 5-48 SECONDARY PAGET DISEASE OF UROTHELIAL ORIGIN The presence of acantholysis and clefting between malignant cells and squamous epithelium is more often seen with spread of a urothelial primary (left). Nonetheless, the lesion may bear close More about this image found in SECONDARY PAGET DISEASE OF UROTHELIAL ORIGIN The presence of acantholysis ...

UROTHELIAL CARCINOMA METASTATIC TO THE CERVIX Figure 3-77 UROTHELIAL CARCINOMA METASTATIC TO THE CERVIX Left: In this case, spread occurred in a pagetoid fashion, and was initially interpreted as an HSIL of the cervix. Right: The primary lesion in the bladder, depicted here, shows identical More about this image found in UROTHELIAL CARCINOMA METASTATIC TO THE CERVIX Left: In this case, spread o...
