Primary sarcomatoid urothelial carcinoma of the ureter with heterologous elements is rare and carries a poor prognosis. Although there is some literature on primary bladder sarcomatoid urothelial carcinoma, ureteric involvement has been reported infrequently, and this case report describes this unusual histological finding with concurrent divergent squamous differentiation. Despite laparoscopic radical nephroureterectomy, our patient died within six months of diagnosis with local recurrence and metastatic spread. A more thorough understanding of this disease process and consideration of standardised guidelines for treatment are needed to improve patient outcomes.

Urothelial carcinoma (UC) is the most common histological subtype of bladder tumors; however, bladder cancer represents a heterogeneous group of diseases with at least 40 distinct histological subtypes. Among these, the 2022 World Health Organization classification of urinary tract tumors identifies a range of less common subtypes of invasive UC, formerly known as variants, which are considered high-grade tumors, including squamous cell, small-cell, sarcomatoid urothelial, micropapillary, plasmacytoid, and urachal carcinomas, and adenocarcinoma. Their accurate histological diagnosis is critical for risk stratification and therapeutic decision-making, as most subtype histologies are associated with poorer outcomes than conventional UC.

Objective: To investigate the expression patterns of Nectin-4, the target molecule of the antibody-drug conjugate enfortumab vedotin (EV), in relation to histological and molecular subtypes of urothelial bladder cancer (UBC).
Patients And Methods: We assessed the protein expression patterns of Nectin-4 in a spatially organised tissue microarray containing 1386 tissue cores from 314 consecutive patients with UBC who underwent radical cystectomy (2005-2018). Results were correlated with clinicopathological and follow-up data, as well as with different spatial locations (tumour central vs tumour-normal interface and primary tumour vs lymph node [LN] metastases).

Purpose: Most bladder cancers are pure urothelial carcinomas, but a small portion, approximately 5-10%, have variant histology or are non-urothelial in nature. This research sought to examine the features of and treatment strategies for different types of urothelial carcinoma with variant histologies and non-urothelial bladder cancer.
Methods: The study cohort comprised individuals with non-urothelial and variant urothelial bladder cancers treated at two medical centres in Ankara, Turkey, between 2005 and 2024.

Bladder cancer is one of the main causes of urogenital cancer (30-35% of the total urological cancers). Although metastases from urologic tumors are rare, it is associated with a high mortality rate. The location and pattern of metastasis are random and unpredictable.

A 68-year-old male was referred to our hospital because plain computed tomography (CT) showed right hydronephrosis. Contrast-enhanced CT revealed a mass with an irregular margin and poor contrast effect in the lower pole of the right kidney, which invaded the perirenal fat tissues and the area around the inferior vena cava (IVC). Moreover, a thrombus extending from the right renal vein to the IVC was detected, some of which was suggestive of tumor components on contrast-enhanced magnetic resonance imaging (MRI).
