For example, what are the connotations/nuances behind a diagnosis of “nested variant of urothelial carcinoma There is evidence that multifocal urothelial carcinoma can arise through independent concurrent genetic events at multiple locations in the lower urinary tract. 138, 139 Other studies, however Urothelial neoplasms with squamous morphology raise the differential diagnosis between pure primary squamous cell carcinoma, urothelial carcinoma with squamous differentiation and secondary involvement by squamous cell carcinoma, for example, from uterine cervix. Accurate identification between thes … (b) High-grade urothelial carcinoma reveals expression of CK20 in all layers of urothelium except for the basal layer which contains CK5/6. This may represent an intermediate stage of dedifferentiation of the tumor.

Abstract. Urothelial carcinomas of the renal pelvis are relatively rare tumors, and large series that include clinicopathologic and outcome data are few. We reviewed 130 consecutive nephroureterectomies performed for urothelial carcinoma of the renal pelvis at our institution. Tumors were graded using the World Health Organization/International Society of Urologic Pathologists (WHO/ISUP) grading system and were staged according to the 2002 TNM classification; 83 (63.6%) of the patients were

The WHO/International Society of Urological Pathology 1998 classification system In 1997, a new multidisciplinary consensus meeting was held to revisit terminology and provide updated recom-mendations to the WHO on the pathology of urothelial carcinomas. The WHO/International Society of Urological Pathology (ISUP) Nested variant of urothelial carcinoma is a deceptively benign-appearing neoplasm with potential of deep invasion and metastases. Immunohistochemically, nested variant of urothelial carcinoma shares some features with high-risk conventional urothelial carcinomas, such as loss of p27 expression and high proliferation index. Adenocarcinoma of the urinary bladder arising from the urothelial lining is an uncommon malignant neoplasm, accounting for 0.5% to 2.0% of all malignant vesical tumors.1 The histologic variants show a predominant colonic (enteric) type glandular morphology with varied histologic patterns.

By Bahram Robert Oliai, M.D. Although most of us are familiar with the features, behavior and treatment of the “usual” type urothelial (so-called transitional cell)carcinoma, what do we do when the pathology report comes back with an unexpected and unusual diagnosis? For example, what are the connotations/nuances behind a diagnosis of “nested variant of urothelial carcinoma
