Abstract
Various types of human cancer may develop aberrant trophoblastic differentiation, including histological changes and altered expression of β‑human chorionic gonadotropin (β‑hCG). Aberrant trophoblastic differentiation in epithelial cancer is usually associated with poor differentiation, tumor metastasis, unfavorable prognosis and treatment resistance. Since β‑hCG‑targeting vaccines have failed in an early phase II trial, it is crucial to obtain a better understanding of the molecular pathogenesis of trophoblastic differentiation in human cancer. The present review summarizes the clinical and translational research on this topic with the aim of accelerating the development of an effective targeted therapy. Ectopic expression of β‑hCG promotes proliferation, migration, invasion, vasculogenesis and epithelial‑mesenchymal transition (EMT) in vitro, and enhances metastatic and tumorigenic capabilities in vivo. Signaling cascades modulated by β‑hCG include the TGF‑β receptor pathway, EMT‑related pathways, the c‑MET receptor tyrosine kinase and mitogen‑activated protein kinase/ERK pathways, and the SMAD2/4 pathway. Taken together, these findings indicated that TGF‑β receptors, c‑MET and ERK1/2 are potential therapeutic targets. Nevertheless, further investigation on the molecular basis of aberrant trophoblastic differentiation is mandatory to improve the design of precision therapy for this aggressive type of human cancer.

Abstract
Bladder cancer researchers and clinicians have increasingly viewed tumor biology through the lens of genomic and molecular alterations, drastically improving our knowledge of the underlying disease biology. This understanding has led to significant advances in treatment options that allow implementation of a personalized approach to cancer treatment. Large-scale genomic studies initially focused on the most common forms of bladder cancer. However, as genomic and molecular technologies become more widespread and are applied to less common variant histologies, we are gaining additional insight into the unique molecular and genomic characteristics driving the biology of variant histologies of bladder cancer. In this review, we summarize the current state of knowledge of molecular alterations underlying the distinct tumor biology of plasmacytoid urothelial carcinoma and how these alterations may impact treatment options.

Abstract
Trophoblastic differentiation (including choriocarcinoma) arising in urothelial carcinoma has been described in numerous case reports, but never in a single series. We present a series of these tumors, describing the morphologic spectrum, applying traditional and novel immunohistochemical stains, and characterizing clinical follow-up. We identified 16 cases, arising predominantly in the bladder (N=14), but also the ureter (N=1) and prostatic urethra (N=1). Six of our cases (38%) contained invasive urothelial carcinoma with admixed syncytiotrophoblasts, 8 cases (50%) consisted of invasive urothelial carcinoma with choriocarcinoma, 1 case (6%) showed urothelial carcinoma in situ with associated choriocarcinoma, and 1 case (6%) consisted of pure choriocarcinoma. Other subtypes of variant morphology were seen in 5 of our cases (31%) and included squamous, glandular, lipoid, chordoid/myxoid, and sarcomatoid features. Given the limited specificity of human chorionic gonadotropin immunohistochemistry, we also studied the expression of a novel specific trophoblastic marker, hydroxyl-δ-5-steroid dehydrogenase, as well as Sal-like protein 4. Human chorionic gonadotropin expression was seen in nearly all cases (93%) but was often not limited to the trophoblastic component, staining the urothelial component also in 85% of the cases. Expression of hydroxyl-δ-5-steroid dehydrogenase was more sensitive and more specific, staining 100% of the cases and limited to trophoblasts in all but 1 case. Sal-like protein 4 expression was variable, staining trophoblast in only 50% of cases and staining the urothelial carcinoma component in 43% of those positive cases. Most of our tumors presented at a high stage and were associated with poor clinical outcomes, with at least muscle-invasive disease (pT2) in 10 of the 14 bladder tumors (71%), periureteric fat invasion in the ureter tumor (pT3), distant metastases in 7 of 16 cases (44%) and death of disease in 3 of the 15 patients with follow-up (20%). Our study describes a series of urothelial carcinomas with trophoblastic differentiation, demonstrating the morphologic spectrum of this entity, its frequent association with other subtypes of variant morphology, its characteristic immunoprofile, and its aggressive clinical behavior.

Abstract
Background The tumor transformation mechanism of a plasmacytoid urothelial carcinoma remains unexplained. We describe the case of a plasmacytoid urothelial carcinoma of the renal pelvis in which the expression of zinc finger E–box–binding homeobox 1 (ZEB1), a key nuclear transcription factor in an epithelial–mesenchymal transition, is involved in tumor transformation. Case presentation The patient had a left nephrectomy with the clinical diagnosis of left pelvic renal cancer. The resected specimen showed that the tumor surface comprised a noninvasive papillary urothelial carcinoma with the carcinoma in situ, and the invasive area comprised a plasmacytoid urothelial carcinoma characterized by the presence of single dyscohesive malignant cells that resembled plasma cells in a loose myxoid stroma. The noninvasive urothelial carcinoma was positive for cytokeratin and E–cadherin, and negative for vimentin and ZEB1. In contrast, the invasive plasmacytoid urothelial carcinoma was positive for cytokeratin and also vimentin and ZEB1, and negative for E–cadherin. Additionally, this component was immunoreactive for CD138 and CD38 that are immunohistochemical markers for plasma cells. Conclusion We suggest that ZEB1 is involved in the plasmacytoid transformation by repressing the E–cadherin in a plasmacytoid urothelial carcinoma.

Abstract
Urothelial carcinoma is the most common histologic subtype of bladder cancer, accounting for approximately 90%. We herein report a case of a 78-year-old man with an unusual association of bladder stones with an aggressive plasmacytoid variant of urothelial cancer. Initially he presented in 2009 with a very large bladder stone and was treated by an open cystolithotomy. Histology from a bladder biopsy at that time was benign. He failed to attend follow-up appointments but subsequently he attended in 2016 with a recurrent urinary tract infection and an acute kidney injury. A CT scan showed multiple bladder stones. The cause of our patients' multiple bladder stones is unclear and unusual. He then underwent a further open cystolithotomy according to our multidisciplinary team recommendation. Post-operatively he unfortunately developed a non-healing vesicocutaneous fistula for which he was performed cystoscopy and biopsy but ended with transurethral resection due to the extent of abnormal/necrotic tissue. Histology confirmed a plasmacytoid variant of urothelial cancer. To our knowledge, this is the first case of an association of bladder stones with a plasmacytoid variant of urothelial cancer.

Abstract
Background A new molecular marker of carcinoma in the urinary bladder is needed as a diagnostic tool or as a therapeutic target. Potential markers include microRNAs (miRNAs), which are short, low molecular weight RNAs 19–24 nt long that regulate genes associated with cell proliferation, differentiation, and development in various cancers. In this study, we investigated the molecular mechanisms by which miR-145 promotes survival of urothelial carcinoma cells and differentiation into multiple lineages. We found miR-145 to regulate expression of syndecan-1, a heparin sulfate proteoglycan. Methods Cell proliferation in the human urothelial carcinoma cell lines T24 and KU7 was assessed by MTS assay. Cellular senescence and apoptosis were measured by senescence-associated β-galactosidase (SA-β-gal) and TUNEL assay, respectively. Quantitative RT-PCR was used to measure mRNA expression of various genes, including syndecan-1, stem cell factors, and markers of differentiation into squamous, glandular, or neuroendocrine cells. Results Overexpression of miR-145 induced cell senescence, and thus significantly inhibited cell proliferation in T24 and KU7 cells. Syndecan-1 expression diminished, whereas stem cell markers such as SOX2, NANOG, OCT4, and E2F3 increased. miR-145 also up-regulated markers of differentiation into squamous (p63, TP63, and CK5), glandular (MUC-1, MUC-2, and MUC-5 AC), and neuroendocrine cells (NSE and UCHL-1). Finally, expression of miR-145 was down-regulated in high-grade urothelial carcinomas, but not in low-grade tumors. Conclusions Results indicate that miR-145 suppresses syndecan-1 and, by this mechanism, up-regulates stem cell factors and induces cell senescence and differentiation. We propose that miR-145 may confer stem cell-like properties on urothelial carcinoma cells and thus facilitate differentiation into multiple cell types.

Abstract
We report two cases of urinary bladder urothelial carcinoma (UC). In both, histological examination of a transurethral resection specimen of the bladder tumor revealed UC with plasmacytoid and micropapillary differentiations. In Case 1, residual plasmacytoid UC deeply invaded the extravesical fat tissue of the radical cystectomy specimen, and metastatic carcinoma was found in almost all the dissected lymph nodes. Despite adjuvant chemotherapy and radiotherapy, the patient died 25 months postdiagnosis. Elevated serum carbohydrate antigen 19-9 (CA19-9) returned to near normal levels after radical cystectomy, but they increased shortly before death. In Case 2, no residual carcinoma was found in the radical cystectomy specimen or lymph nodes. Postoperative serum CA19-9 was maintained at normal levels, and the patient remains alive without recurrence or metastasis. Although plasmacytoid and micropapillary UC are known aggressive variants of UC, plasmacytoid UC may be more aggressive. Serum CA19-9 could serve as a useful biomarker to monitor progression of plasmacytoid UC.

Abstract
BACKGROUND CD138/Syndecan-1 (Sdc-1) is expressed on the tumor and stromal cells of invasive bladder carcinoma. CD138/Sdc-1 shedding from the cell surface is associated with the invasive phenotype in lung and breast cancers. PATIENTS AND METHODS Soluble CD138/Sdc-1 was measured in the sera of 86 bladder cancer patients and 57 healthy individuals by a commercial ELISA assay. RESULTS Soluble Sdc-1 was increased in the sera of patients with bladder cancer (138.42 ± 81.85 vs. 86.48 ± 82.58 ng/ml, p = 0.0003). Patients aged over 70 years had higher levels of CD138/Sdc-1 in their sera (159.7 ± 15.77 vs. 124.5 ± 9.99 ng/ml, p = 0.025), and soluble Sdc-1 levels were higher in the sera of patients with moderately differentiated tumors compared to poorly differentiated ones (170.47 ± 85.06 vs. 101.79 ± 68.24 ng/ml, p = 0.01). The soluble Sdc-1 level was higher in muscle-invasive (154.45 ± 83.60 vs. 89.9 ± 55.02 ng/ml) but not lymphatic-invasive (106.25 ± 52.10 vs. 123.43 ± 63.76 ng/ml) tumors (p = 0.027 and 0.45, respectively). A non-significant trend of soluble Sdc-1 increase in the sera of male patients compared to female patients was observed (145.38 ± 85.47 vs. 110.20 ± 59.04 ng/ml, p = 0.054). CONCLUSION The elevated levels of soluble CD138/Sdc-1 in older bladder cancer patients and those with muscular invasion sheds some light on the mechanisms of the disease invasion.

Abstract
Loss of E-cadherin expression has been linked to the invasive phenotypes of a variety of neoplasms, including lobular breast cancer. The expression of E-cadherin in variants of urothelial carcinoma relative to usual-type urothelial carcinoma, maximum depth of invasion and angiolymphatic invasion has not been well characterized. A total of eight cases of micropapillary urothelial carcinoma, four cases of plasmacytoid urothelial carcinoma, two cases of urothelial carcinoma with signet ring cell differentiation and two cases of urothelial carcinoma with mixed plasmacytoid and signet ring cell differentiation, all obtained from cystectomy/cystoprostatectomy cases, were identified. In all nine cases of usual-type invasive and noninvasive high-grade urothelial carcinoma were also included in the study. Immunohistochemical staining of E-cadherin was performed in all cases. Pathological parameters including depth of invasion and presence of angiolymphatic invasion were documented. Maximum depth of invasion: In micropapillary urothelial carcinoma, extravesical extension was seen in three of eight cases; muscularis propria invasion in four of eight cases; and lamina propria invasion in one of eight cases. In plasmacytoid urothelial carcinoma, extravesical extension was observed in two of four cases, and muscularis propria invasion and lamina propria invasion in one of four cases each. In urothelial carcinoma with signet ring cell differentiation, extravesical extension and muscularis propria invasion was seen in one of two cases each. In urothelial carcinoma with mixed plasmacytoid and signet ring cell differentiation, muscularis propria invasion and lamina propria invasion was observed in one of two cases each. In usual-type high-grade urothelial carcinoma, extravesical extension was seen in six of nine cases and noninvasive in three of nine cases. In angiolymphatic invasion, micropapillary urothelial carcinoma was observed in eight of eight cases; plasmacytoid urothelial carcinoma in two of four cases; urothelial carcinoma with signet ring cell differentiation in one of two cases; and urothelial carcinoma with mixed plasmacytoid and signet ring cell differentiation in one of two cases. Usual-type high-grade urothelial carcinoma was seen in six of nine cases. E-cadherin expression: All eight cases of micropapillary urothelial carcinoma were positive for E-cadherin in the micropapillary component and adjacent usual-type urothelial carcinoma. The four cases of plasmacytoid urothelial carcinoma, two cases of urothelial carcinoma with signet ring cell differentiation and two cases of urothelial carcinoma with mixed plasmacytoid and signet ring cell differentiation were all negative for E-cadherin. All nine additional cases of usual-type high-grade urothelial carcinoma were diffusely positive for E-cadherin. E-cadherin is diffusely positive in usual-type urothelial carcinoma and micropapillary urothelial carcinoma, irrespective of pathological stage and angiolymphatic invasion. Loss of E-cadherin expression may be a marker of plasmacytoid and signet ring cell differentiation in urothelial carcinoma.

Abstract
Heparan sulfate proteoglycan syndecan-1, CD138, is well known to be associated with cell proliferation, adhesion, and migration in various types of malignancies. In the present study, we focused on the role of syndecan-1 in human urothelial carcinoma of the urinary bladder. Silencing of syndecan-1 by siRNA transfection down-regulated transcriptional factor junB and the long isoform of FLICE-inhibitory protein (FLIP long), resulting in the induction of apoptosis in the urothelial carcinoma cell lines UMUC2 and UMUC3. Knockdown of junB and FLIP long as well as syndecan-1 silencing mediated apoptosis that was inhibited by pan-caspase inhibitors. Transurethral injection of syndecan-1 siRNA into the urinary bladder significantly reduced syndecan-1 gene expression and growth of red fluorescent-labeled KU-7/RFP bladder cancer cells in the mouse orthotopic bladder cancer model. Immunohistochemical examination showed high syndecan-1 protein expression in high-grade, superficial, and deep invasive carcinomas (pT1 and >or=pT2) as well as carcinoma in situ, but not in low-grade and noninvasive phenotypes (pTa). In addition, the percentage of cancer cells positive for syndecan-1 at initial diagnosis was statistically associated with the frequency of bladder cancer recurrence after transurethral resection. In conclusion, syndecan-1 might contribute to urothelial carcinoma cell survival and progression; therefore, this molecule could be a new therapeutic target in human urinary bladder cancer.

Abstract
It is well established that invasive urothelial carcinoma, involving the urinary bladder and renal pelvis, has marked propensity for divergent differentiation. In recent years, several 'variant' morphologies have been described and most have been recognized in the 2004 World Health Organization Classification. These histological variants of urothelial carcinoma have clinical significance at various levels, including diagnostic, that is, awareness of the morphological variant is essential in order to avoid diagnostic misinterpretations; prognostic for patient risk stratification; and therapeutic, where a diagnostic assignment of a particular variant may be associated with the administration of a therapy distinctive from that used in conventional invasive urothelial carcinoma. The diagnoses of micropapillary urothelial carcinoma, small-cell carcinoma, lymphoepithelioma-like carcinoma and sarcomatoid carcinoma are prime examples where treatment protocols may be different than the usual muscle-invasive bladder cancer. This review discusses the variants of urothelial carcinoma, outlining for each the diagnostic features, differential diagnostic considerations and the clinical significance.

Abstract
Plasmacytoid bladder cancer is a rare variant of transitional cell carcinoma. A 57-year-old man was referred to our institution for management of invasive transitional cell carcinoma diagnosed at a peripheral hospital. His complaints were of vague lower abdominal pain with associated urgency and frequency requiring oxybutynin. Metastatic workup was negative and was subsequently scheduled for a radical cystectomy. Routine colonoscopy 3 weeks prior to surgery was negative. Intraoperatively, he was found to have metastatic urothelial cancer involving the cecum and multiple metastatic deposits within the mesentery of the small intestines. He underwent a palliative cystectomy with ileal conduit formation. Final pathology revealed metastatic plasmacytoid variant of urothelial cancer. Histology and immunohistochemistry were compatible with plasmacytoid variant of urothelial cancer. Here we present our case of this rare variant of urothelial cancer with a review of its characteristics.

Abstract
In this report, we present the clinicopathologic features of 11 cases of the plasmacytoid variant of urothelial carcinoma. This is a rare variant of bladder cancer recognized by the current World Health Organization classification of urologic tumors. The plasmacytoid component varied from 30% to 100% of the tumor specimen; in 8 cases, the plasmacytoid component comprised greater than 50% of the tumor with 2 cases showing pure plasmacytoid carcinoma. The architectural pattern of the tumor varied from solid expansile nests with noncohesive cells to mixed solid and alveolar growth; a streaking discohesive architecture was additionally present in 2 cases (18%). At histology, the individual tumor cells had an eccentrically placed nucleus and abundant eosinophilic cytoplasm reminiscent of plasma cells. Most neoplastic cells had nuclei of low to intermediate nuclear grade with occasional nuclear pleomorphism. Seven of 9 mixed cases had concurrent conventional high-grade urothelial carcinoma, and the remaining 2 cases presented features of nested or micropapillary urothelial carcinoma. Small intracytoplasmic vacuoles were variably present in all cases. All patients had advanced stage cancer (>pT3), and 8 (73%) had lymph node metastasis. Immunohistochemical staining demonstrated that both plasmacytoid and associated conventional urothelial carcinoma were positive for cytokeratins 7, 20, and AE1/AE3 and epithelial membrane antigen; CD138 was positive in 3 cases. Follow-up information was available in all cases (range, 2-16 months; mean, 7 months). Nine of the patients died of disease from 2 to 11 months, and 2 patients were alive with disease at 8 and 16 months. In summary, plasmacytoid variant of urothelial carcinoma is an aggressive variant associated with poor prognosis that presents at an advanced clinical stage. In limited samples, it may be misdiagnosed as chronic cystitis or plasmacytoma, a pitfall further compounded by CD138 expression in some cases. Morphological distinction from other malignant neoplasms with plasmacytoid phenotype is critical for its clinical management.

Abstract
Bladder cancer is the ninth most common cancer worldwide, and the most common malignancy affecting the urinary tract, with approximately 330,000 new cases and more than 130,000 deaths per year. Bladder cancer is primarily attributable to smoking, which accounts for 65% of male and 30% of female cases in some developed countries. Other major risk factors include analgesic abuse, some types of chemotherapy, occupational exposure to chemicals, and in Egypt and some Asian regions, endemic infection with Schistosoma haematobium. Approximately 90% of bladder tumors are classified as urothelial carcinoma (UC), also referred to as transitional cell carcinoma (TCC), and are believed to originate from transformation of the normal urothelium. UCs often exhibit elements of squamous or glandular differentiation. The spectrum of microscopic forms of urothelial carcinoma has been expanded recently to include several histologic variants, the recognition of which is important to avoid diagnostic misinterpretation, to predict outcome, and to guide the selection of the most appropriate therapeutic approach. This article reviews characteristic pathologic features and key clinical aspects of UC and its most common variants.

Abstract
Urothelial carcinoma is well known for its divergent differentiation. Several "variant" morphologies have been described in the literature in recent years and have additionally been recognized in the recent World Health Organization classification of urothelial neoplasms. The importance of recognizing these variant histologies lies in the potential diagnostic, prognostic, or therapeutic implications that accompany these diagnoses. The range of variant morphology seen in the urinary bladder may also be seen in urothelial tumors of the renal pelvis. Herein we review select variants of urothelial carcinoma focusing on the relatively recently recognized variants, outlining the diagnostic features, common differential diagnostic dilemmas, and clinical relevance. This review also includes a discussion on variants on which there is recent information available.
