Abstract
A sarcomatoid variant of urothelial carcinoma (SVUC) is an extremely rare variant, which accounts for only 0.1-0.3% of all urothelial carcinomas of the bladder. SVUC is distinguished by the presence of biphasic components; there can be morphological and/or immunohistochemical substantiation of epithelial and mesenchymal differentiation. The patients with this variant have been associated with very poor disease-specific and overall survival rates in comparison with the high-grade pure urothelial carcinoma. Being a rare entity, it usually presents at a higher grade and is related to a dismal prognosis in comparison with conventional urothelial carcinoma. Careful examination, early diagnosis, and effective treatment are the most important steps for good survival. Here, we report a 58-year-old male who presented with complaints of hematuria for one and a half months with histopathology showing features of SVUC.

Abstract
Urothelial cell carcinoma is the most common malignant tumor of the urinary tract, which develops in the renal pelvis, ureter, and bladder, and rarely it develops in the ureter. Histologically, urothelial cell carcinoma is categorized into non-invasive and invasive forms. Non-invasive urothelial cell carcinoma has papillary growth, it is usually well differentiated, and has a favorable outcome, while invasive urothelial cell carcinoma infiltratively spreads the organs of origin, it is typically poorly differentiated, and often associated with a poor prognosis. In the case of invasive urothelial cell carcinoma, the clinical course is primarily determined by the depth of invasion, but according to recent data, morphological variants of urothelial cell carcinoma respond differently to oncological treatments, and their biological behavior is also distinct. These subtypes and variants are significantly underdiagnosed in Hungary and internationally because the criteria for histological diagnosis are not clear for many subsets. The latest 2022 WHO classification of urinary tract tumors significantly clarified the definitions of various subtypes and variants. In this paper, utilizing the current classification, we review and explain these subtypes' morphological, immunohistochemical, differential diagnostic, prognostic, and predictive characteristics intending to make them appear as much as possible in everyday diagnostic practice. Also, the work aims to present the individual urothelial cell carcinoma subtypes and variants to the Hungarian community of pathologists, oncologists, and urologists, so that the previously high level of urological oncology care can become even more personalized.

Abstract
Sarcomatoid urothelial carcinoma (SUC), a rare tumor of the urinary tract epithelium, exhibits a high degree of malignancy and therefore a poor prognosis. Due to the absence of specific clinical presentations and imaging findings, SUC of the renal pelvis masquerades as a renal abscess is frequently under-recognized or misdiagnosed as benign inflammatory disease, resulting in delayed or erroneous treatment. Here, we report a patient with SUC of the renal pelvis who presented with a renal abscess. Repeated anti-inflammatory treatment was ineffective. Unexpectedly, cancerous cells were detected in subsequent exfoliative cytology of nephrostomy drainage fluid. In accordance with this, radical surgery and postoperative chemotherapy were conducted. Fortunately, neither recurrence nor metastasis occurred during a one-year follow-up.

Abstract
Infiltrating urothelial carcinoma sarcomatoid variant is a rare variant of urothelial carcinoma. We report a case of a 68-year-old female with a history of hematuria. CT scan with contrast showed a mass in the 1/3 distal of the right ureter. The biopsy result showed a high-grade infiltrating urothelial carcinoma. A radical nephroureterectomy was performed but at the follow-up after 3 months, there was a recurrent mass and gemcitabine-cisplatin chemotherapy was given. Since a high-grade infiltrating urothelial carcinoma sarcomatoid variant was an aggressive tumor, we need to give more attention to evaluating this tumor.

Abstract
Sarcomatoid urothelial carcinoma (UC) of the renal pelvis is rare. It is a high-grade malignant tumor that contains both epithelial and mesenchymal elements. Brain metastases from renal pelvis UC are infrequent and represented in few cases. We report a 68-year-old female with a right renal mass diagnosed as a UC with a sarcomatoid variant. The patient underwent a right radical nephroureterectomy and received chemotherapy. She developed brain metastasis in the left temporal area two months later. Therefore, metastasectomy and palliative brain radiotherapy were performed for her. Sadly, her general condition worsened, and she passed away after one month. Brain metastasis in patients with UC is rare and poorly understood. Therefore, we describe the clinico pathological characteristics, including the clinical follow-up of our case with a focus on the treatment and outcome.

Abstract
Invasive urothelial carcinoma has a propensity for disparate differentiation and presentation of morphological variants. Sarcomatoid carcinoma (SaC) of the bladder is an extremely uncommon and aggressive variant of bladder cancer. An accurate diagnosis for this variant is necessary, but at times difficult. Immunohistochemistry can increase the diagnostic accuracy for SaC. The therapeutic approaches currently adopted for the treatment of SaC are similar to those used for the urothelial variant: Surgery, chemotherapy and radiation therapy. To date, however, there exists no standard treatment due to the lack of knowledge regarding the pathogenesis of SaC. Future research is required to focus on this rare histological tumor subtype in order to identify more effective treatment strategies. The present study reported an unusual case of bladder SaC in a woman aged 48 years, who was a non-smoker with a long history of benzodiazepine abuse. Although saving the patient's life was a priority, it was also essential to consider her subsequent quality of life. For that reason, the patient underwent a cystectomy with orthotopic neobladder reconstruction using ileum, followed by chemotherapy. At the 7 month follow-up, the patient was still alive, in complete remission and had normal bladder function. The present case report shows the potential contribution of benzodiazepine abuse in the development of a bladder sarcomatoid carcinoma, a rare variant of BC, whose early detection and accurate diagnosis are key to attaining satisfactory treatment outcomes and a favorable prognosis for patients.

Abstract
Carcinosarcoma of the urinary bladder is a very rare and aggressive subtype of bladder cancer with poor prognosis. Characteristically carcinosarcomas exhibit biphasic nature with both epithelial and mesenchymal differentiation. Limited information is available regarding its clinical features and appropriate treatments due to its rarity. Development of tumour models can further our understanding of bladder carcinosarcoma. We report establishment and characterization of the first-ever bladder carcinosarcoma cell line MaS-3. It is established by the outgrow method from 86 year-old caucasian male who underwent a radical pelvic resection after neoadjuvant radiotherapy. MaS-3 showed carcinosarcoma profile with high conformity with to the original tumour in terms of immunocytochemistry. Proteome analysis also aligned the MaS-3 cell line with the carcinosarcoma specimen rather than corresponding non-malignant tissue. Chemotherapy sensitivity testing revealed a great sensitivity of MaS-3 growth to 5-Fluorouracil, Gemcitabine and Cisplatin, with almost no impact of Irinotecan. Additionally, the suitability of MaS-3 for 3D in vitro experiments was also demonstrated. The newly established cell line MaS-3 shows typical characteristics of the tumour and may thus be a useful in vitro model system for studying the tumour biology and developing future of treatments of this rare but very aggressive entity.

Abstract
BACKGROUND Histology is one of the most important factors determining the prognosis of bladder cancers and rare variants are generally associated with decreased disease specific survival compared to pure transitional cell carcinomas. We believe that rare bladder cancer variants are likely underdiagnosed in the absence of a dedicated uro-pathologist in many centers. The objective of this study is to evaluate the contribution of a dedicated uro-pathologist on the identification of rare bladder cancer variants. METHODS We retrospectively analyzed the clinical and histological records of all patients which underwent a radical cystectomy and lymph node dissection between January 2000 and September 2015. The sample was divided in two groups: Group A, consists of patients who underwent radical cystectomy in the absence of a dedicated uro-pathologist at our institution, whereas the Group B consists of patients who underwent surgery when a dedicated uro-pathology service was available. We then evaluated the impact of a dedicated uro-pathologist on rare variants detection. RESULTS One hundred thirty-seven out of 551 (24.9%) of patients who underwent RC had at least one rare variant. In Group A 38/238 (16%) of patients showed a rare variant, while 99/313 (31.6%; P<0.001) in group B. Furthermore, the diagnosis of sarcomatoid variant was statistically significantly less common in group A (P=0.0026). The concordance between final radical cystectomy histology and previous transurethral resection of bladder tumor (TURBT) histology was poor in both groups (overall 50.4%). CONCLUSIONS The presence of a dedicated urological anatomical pathologist is of paramount importance and significantly increases the detection rate of non-transitional cell carcinoma bladder cancer types, but it does not increase the concordance rate between histological diagnoses in TURBT and radical cystectomy specimens.

Abstract
Background Sarcomatoid urothelial carcinoma is a very dangerous malignant tumour derived from the epithelium. Primary sarcomatoid carcinoma of the ureter is extremely rare in clinical practice. The prognosis of this kind of disease is really poor, and there is still not a diagnosis standard in the world. Case presentation An 82-year-old female patient who had intermittent waist pain without any other symptoms, had diagnosed as urothelial cancer on computerised tomography urography. Considering the patient’s age and quality of life, we made a preserving kidneys resection of the local tumour. The tumour was composed of sarcomatous and carcinomatous elements, and immunohistochemical examination showed that tumour cells were positive for cytokeratin, epithelial membrane antigen, vimentin, and GATA3 markers. There were no complications after 1-hour surgery. After 3 months, there was no signs of recurrence and metastasis. Conclusion This case was a patient with sacomatoid urothelial carcinoma. Through a transurethral resection with laser, the patient recovered well, and there was no sign of any recurrence of the tumour after 3 months. With the development of technology and science, more and more cancerous patients’ living quality and survival rate were improved. Maybe it is essential for urologists and scientists to entirely understand the characteristics of the sarcomatoid urothelial carcinoma and make a better clinical guideline.

Abstract
Sarcomatoid variant of urothelial carcinoma (SVUC) of the renal pelvis is a rare entity. To the best of our knowledge, around 25 cases of this neoplasm have been reported in the literature to date, most of which were of high stage. The inferior vena cava tumour thrombus, which is a hallmark of renal cell carcinoma (RCC), may rarely be found in urothelial carcinoma of renal pelvis. In this report, a case of SVUC associated with tumour extension to inferior vena cava is documented. This association has been encountered in only one previously reported case. The possibility of urothelial carcinoma of the renal pelvis should therefore be included in the differential diagnosis of tumour thrombus of the inferior vena cava.

Abstract
In Brazil, without considering the non-melanoma skin tumors, bladder cancer in
men is the eighth most common, and the urothelial carcinoma or transitional cell
carcinoma is the most common among these. Cutaneous metastases from urothelial
neoplasms appear as single or multiple erythematous, infiltrated nodules or
plaques, and like other cases of distant disease, it is indicative of poor
prognosis. The invasive urothelial carcinoma is recognized for its ability to
present divergent differentiation and morphological variants. The sarcomatoid
urothelial carcinoma is a rare cancer that consists of two different components:
one composed of epithelial tissue and the other with sarcomatoid features of
mesenchymal origin. The authors describe a case of cutaneous metastasis of
sarcomatoid urothelial carcinoma in a 63-year-old male patient.
