Abstract
Background Condyloma acuminatum is a squamous epithelial lesion which uncommonly involves the urinary tract. In this location, non-invasive papillary urothelial carcinoma constitutes one of the main differential diagnoses with significant prognostic and therapeutic implications. To date, no ancillary immunohistochemical stain has been described to differentiate these two entities. We assess the utility of cytokeratin 5/6 (CK5/6) and GATA-3 immunohistochemistry in distinguishing condyloma acuminatum from non-invasive papillary urothelial carcinoma. Design We reviewed 9 condylomata acuminata involving the urinary tract, 12 low-grade and 8 high-grade non-invasive papillary urothelial carcinomas. CK5/6 immunostaining was performed in all cases. GATA-3 immunostaining and low-risk human papilloma virus (HPV) chromogenic in situ hybridization was performed in all condyloma cases and 2 urothelial carcinomas with squamous differentiation. Results 8/9 condylomata acuminata were positive for low-risk HPV. All condylomata acuminata exhibited strong full-thickness cytoplasmic staining for CK5/6. In 10 of 12 low-grade non-invasive papillary urothelial carcinomas, CK5/6 expression was continuous and limited to the basal cell layer, while it was patchy and limited to the basal cell layer in all 8 high-grade non-invasive papillary urothelial carcinomas. Two low-grade non-invasive papillary urothelial carcinomas showed focal full-thickness CK5/6 expression in the areas of squamous differentiation. These 2 cases were negative for low-risk HPV. GATA-3 immunostaining was positive in all condylomata acuminata. Conclusions CK5/6 immunostaining is a useful and simple tool that can help separate low-grade and high-grade non-invasive papillary urothelial carcinomas from condyloma acuminatum involving the urothelium-lined organs. GATA-3 has no discriminatory role between condyloma acuminatum and papillary urothelial carcinomas.

Abstract
Condyloma acuminatum rarely occurs in the urinary bladder and is considered to be a risk factor for squamous cell carcinoma, although there are only a few publications with limited cases. We studied 51 cases of condyloma acuminatum of the urinary bladder from transurethral resections of the urinary bladder of 38 patients from the consult files of one of the authors. Transurethral resections of the urinary bladder were obtained from 25 males with a median age of 73 years (range: 41 to 87 y) and 13 females with a median age of 68 years (range: 30 to 86 y). The follow-up period ranged from 15 months to 20 years (median: 6 y). Bladder lesions were accompanied by urethral lesions in 4 men. Eight patients (8/38; 21.0%) had a history of immunosuppression. Seven patients (7/8; 87.5%) from this group had multiple and/or recurrent condylomas. One patient (1/38; 2.6%) with renal transplantation had 10 separate bladder condylomas over time. One patient (1/38; 2.6%) had extensive anogenital condylomas and anal intraepithelial neoplasia grade 3. One patient (1/8; 12.5%) with renal transplantation presented with a solitary condyloma with synchronous squamous cell carcinoma in situ. Three female patients (3/38; 7.9%) had a history of premalignant vagina/cervix lesions. In total, 17 patients (17/38; 44.7%) had squamous cell carcinoma of the bladder, either invasive or in situ. In all cases, the squamous cell carcinoma (either in situ or invasive) was diagnosed either concurrent with the diagnosis of bladder condyloma or within 1 year of the condyloma diagnosis). In total, 9 of 38 (23.7%) patients had invasive squamous cell carcinoma with or without in situ squamous cell carcinoma. Eight of 38 (21.0%) patients had squamous cell carcinoma in situ only (without a definitive invasive component-in 3 cases invasive squamous cell carcinoma could not be excluded with certainty). In total, 19 patients (19/38; 50%) were positive for either low-risk human papillomavirus (LR-HPV) or high-risk human papillomavirus (HR-HPV) or both (3 were positive for both LR-HPV and HR-HPV, 12 patients for only LR-HPV, and 4 for only HR-HPV). Of the 19 patients that were negative for both LR-HPV and HR-HPV, 9 of 19 (47.4%) patients had associated squamous cell carcinoma. Of the 12 patients with only LR-HPV, 4 (33.3%) had associated squamous cell carcinoma (either invasive or in situ). Of the 7 patients with HR-HPV (with or without LR-HPV), 4 (57.1%) has associated squamous cell carcinoma. In summary, condyloma acuminatum of the urinary bladder shows a strong association with squamous cell carcinoma of the bladder, regardless of the condyloma's HPV in situ hybridization results. Immunosuppression is associated with condylomas of the bladder. It is important to distinguish bladder condylomas from papillary urothelial carcinoma, given their different risks for panurothelial disease and risk of squamous cell carcinoma. Recognition of bladder condylomas histologically is often challenging given their rarity, and that they can be negative for both LR-HPV and HR-HPV. The lack of a history of other anogenital human papillomavirus-related lesions further increases the difficulty in establishing the correct diagnosis.

Abstract
Condyloma acuminatum is an anogenital lesion caused by the human papillomavirus infection. It is a common, sexually transmitted disease. It usually affects the external genitalia, while urethral and bladder involvement is uncommon. Human papillomavirus types are classified into three categories depending on their oncogenic potential: low risk (type 6, 11, 42, 43, 44, 59, 66, 68, and 70), intermediate-risk (type 30, 31, 33, 34, 35, 39, 40, 49, 51, 52, 53, 57, 58, 63, and 64) and high risk (type 16, 18, 45, and 56). High-risk and intermediate-risk human papillomavirus DNA types, together with other co-factors still to be defined, account for over 90% of anogenital pre-malignant and malignant tumours. Herein, we report a unique case of condyloma acuminatum positive for human papillomavirus -6 involving the penile urethra, presents as the primary and only site of the disease in a diabetic type-2 patient.

Abstract
The discovery of bacteria in the female urinary bladder has fundamentally changed current dogma regarding the urinary tract and related urinary disorders. Previous research characterized many of the bacterial components of the female urinary tract, but the viral fraction of this community is largely unknown. Viruses within the human microbiota far outnumber bacterial cells, with the most abundant viruses being those that infect bacteria (bacteriophages). Similar to observations within the microbiota of the gut and oral cavity, preliminary surveys of the urinary tract and bladder microbiota indicate a rich diversity of uncharacterized bacteriophage (phage) species. Phages are vital members of the microbiota, having critical roles in shaping bacterial metabolism and community structure. Although phages have been discovered in the urinary tract, such as phages that infect Escherichia coli, sampling them is challenging owing to low biomass, possible contamination when using non-invasive methods and the invasiveness of methods that reduce the potential for contamination. Phages could influence bladder health, but an understanding of the association between phage communities, bacterial populations and bladder health is in its infancy. However, evidence suggests that phages can defend the host against pathogenic bacteria and, therefore, modulation of the microbiome using phages has therapeutic potential for lower urinary tract symptoms. Furthermore, as natural predators of bacteria, phages have garnered renewed interest for their use as antimicrobial agents, for instance, in the treatment of urinary tract infections.

Abstract
BACKGROUND The increasing availability of high-throughput sequencing data provides researchers with unprecedented opportunities to investigate viral genetic elements in host genomes that contribute to virus-linked cancers. Almost all of the available computational tools for secondary analysis of sequencing data detect viral infection or genome integration events. However, viral oncogenes expression is likely of importance in carcinoma. We therefore developed a new software, DisV-HPV16, for the evaluation of HPV16 oncogenes expression. RESULTS HPV16 virus and viral oncogenes expression was detected more rapidly using DisV-HPV16 compared to other software. DisV-HPV16 was proved highly convenient for detecting candidate virus after modification of the reference file. The accuracy of DisV-HPV16 was empirically confirmed in laboratory experiments. DisV-HPV16 exhibited greater reliability than other software. CONCLUSIONS DisV-HPV16 is a new, dependable software to detect virus and viral oncogenes expression through analysis of RNA sequencing data. Use of DisV-HPV16 can yield deeper, more comprehensive insights into virus infection status and viral and host cell gene expression.

Abstract
Condyloma acuminata (CA) are warty lesions caused by human papilloma virus (HPV) that generally affect the external genitalia and mucocutaneous junctions. Involvement of the urinary tract is rare, and involvement of the urinary bladder is thought to be due to immunosuppression. A 30-year-old woman was diagnosed with urethral CA 12 months after renal transplantation. She underwent transurethral resection (TUR) of the urethral lesions. During the operation, multiple sessile warty lesions were found incidentally inside the bladder and were also removed by TUR. The patient's postoperative course was uneventful. Pathological examination confirmed that the lesions were CA. Multiplex real-time polymerase chain reaction was performed to confirm the HPV genotype and revealed type 45 HPV DNA. CA of the urethra are uncommon, and bladder involvement is extremely rare. This case is the first reported, to our knowledge, to involve HPV type 45 in bladder condyloma. TUR may be the preferred option for the management of CA in the urinary bladder.

Abstract
Condyloma acuminata (CA) is a warty lesion caused by the sexually transmitted human papillomavirus that most commonly affects external genitalia and mucocutaneous junctions. Involvement of the urinary tract (UT) is rare. Anogenital CA is considered a predisposition for urethral and subsequently bladder involvement. Isolated urinary bladder involvement is thought to be due to immunosuppression. A 60-year-old man presented with progressively worsening lower UT symptoms, which culminated in acute urinary retention due to histologically proven benign prostatic obstruction (BPO). He had neither cutaneous nor anogenital CA, and viral markers were unremarkable. He had failed a trial of voiding without catheter and had simple prostatectomy 2 years later. Findings at surgery included an enlarged prostate with prominent median lobe and a sessile, warty lesion of 1.2 cm in the widest diameter found incidentally at the dome of the bladder, which turned out to be CA after histopathological analysis of excisional biopsy specimen. CA of the urethra is uncommon while that of the bladder is rare. CA of the bladder without preceding anorectal CA or immunosuppression is uncommon. There is no report of CA of the bladder in BPO till date. Complete surgical excision is the preferred option of management except when not practicable.

Human papillomavirus E6 triggers upregulation of the antiviral and cancer genomic DNA deaminase APOBEC3B. mBio 2014; 5:mBio.02234-14.

Abstract
Several recent studies have converged upon the innate immune DNA cytosine deaminase APOBEC3B (A3B) as a significant source of genomic uracil lesions and mutagenesis in multiple human cancers, including those of the breast, head/neck, cervix, bladder, lung, ovary, and other tissues. A3B is upregulated in these tumor types relative to normal tissues, but the mechanism is unclear. Because A3B also has antiviral activity in multiple systems and is a member of the broader innate immune response, we tested the hypothesis that human papillomavirus (HPV) infection causes A3B upregulation. We found that A3B mRNA expression and enzymatic activity were upregulated following transfection of a high-risk HPV genome and that this effect was abrogated by inactivation of E6. Transduction experiments showed that the E6 oncoprotein alone was sufficient to cause A3B upregulation, and a panel of high-risk E6 proteins triggered higher A3B levels than did a panel of low-risk or noncancer E6 proteins. Knockdown experiments in HPV-positive cell lines showed that endogenous E6 is required for A3B upregulation. Analyses of publicly available head/neck cancer data further support this relationship, as A3B levels are higher in HPV-positive cancers than in HPV-negative cancers. Taken together with the established role for high-risk E6 in functional inactivation of TP53 and published positive correlations in breast cancer between A3B upregulation and genetic inactivation of TP53, our studies suggest a model in which high-risk HPV E6, possibly through functional inactivation of TP53, causes derepression of A3B gene transcription. This would lead to a mutator phenotype that explains the observed cytosine mutation biases in HPV-positive head/neck and cervical cancers. The innate immune DNA cytosine deaminase APOBEC3B (A3B) accounts for a large proportion of somatic mutations in cervical and head/neck cancers, but nothing is known about the mechanism responsible for its upregulation in these tumor types. Almost all cervical carcinomas and large proportions of head/neck tumors are caused by human papillomavirus (HPV) infection. Here, we establish a mechanistic link between HPV infection and A3B upregulation. The E6 oncoprotein of high-risk, but not low-risk, HPV types triggers A3B upregulation, supporting a model in which TP53 inactivation causes a derepression of A3B gene transcription and elevated A3B enzyme levels. This virus-induced mutator phenotype provides a mechanistic explanation for A3B signature mutations observed in HPV-positive head/neck and cervical carcinomas and may also help to account for the preferential cancer predisposition caused by high-risk HPV isolates.

Abstract
Several recent studies described that high-risk human papillomavirus (HPV) infection could have a potential role in the development of malignancies other than cervical cancer, such as laryngeal carcinoma, penile carcinoma, and anal carcinoma. However, the etiological role of HPV infection in the pathogenesis of urinary tract has not been clarified. Many epidemiological studies demonstrated that HPV infections frequently occur in the external genitalia through sexual contact; however, it was reported that HPV infection could also occur in the urinary tract, including the urethra and urinary bladder. Some morphological changes of cells associated with HPV infection and mild atypical cells, suspected to be intraneoplasia, were seen in HPV-positive samples obtained from the urinary tract. Some clinical studies and meta-analysis have indicated that HPV infection is likely to have a certain etiological correlation with the development of bladder carcinoma, although its prevalence may vary according to HPV type, study population, region, histological type, detection methods, and other variables. According to the results of previous studies, the prevalence of HPV greatly widely varies in cases of bladder carcinoma. Further research by case-control or large-scales studies is thus required to reach a more definite conclusion.

Abstract
Squamous cell carcinomas of the urinary bladder are rare in the Western world; the majority of cases are reported in countries endemic to Schistosoma parasitic infections. Unlike squamous tumors of the uterine cervix or oropharynx, the human papillomavirus (HPV) is not commonly associated with bladder squamous cell carcinomas. We report on two cases of HPV-positive urothelial carcinomas of the urinary bladder with extensive squamous differentiation showing the typical basaloid, poorly differentiated morphology of HPV-associated tumors. These occurred in patients with neurogenic bladders who had long-standing histories of self-catheterization with tumors that tested positive for HPV by in situ hybridization. A retrospective review of our institutional database revealed four additional patients with bladder tumors showing squamous differentiation arising in the setting of neurogenic bladder. Review of these cases showed the more common well-differentiated keratinizing appearance of squamous cell carcinomas of the bladder. These tumors showed only patchy positivity for p16 immunohistochemical stain (not the diffuse strong staining seen in HPV-positive tumors), and the one tested case was negative for HPV by in situ hybridization. HPV infection and neurogenic bladder have been independently associated with increased risk of developing carcinoma in the urinary bladder; however, this is the first report of squamous tumors arising in the setting of concurrent neurogenic bladder and HPV infection. The morphology of these tumors is similar to that of other high-risk HPV-associated squamous carcinomas with a basaloid, poorly differentiated appearance and little to no keratin formation.
