Abstract
We report a case of a cervical intraepithelial neoplasia associated with epidermodysplasia verruciformis human papillomavirus (HPV) type 5 and HPV type 16 in a human immunodeficiency virus-infected patient. Furthermore, epidermodysplasia verruciformis-like cutaneous eruptions after initiation of highly active antiretroviral therapy has never been described as a manifestation of an immune restoration syndrome.

Abstract
A 25-year-old black man had a 20-year history of disseminated plaques on his body. Two years before consultation he noticed several tumors on the genitalia. Physical examination revealed generalized, coalescing, hypopigmented plaques with a very defined and keratotic border that resembled actinic porokeratosis. (Fig. 1). Multiple verrucous and moist tumors were observed on the scrotum (Fig. 2). His past medical history was unremarkable, and no family member had the disease. Histology of the body lesions revealed hyperkeratosis with a horny-layer, basket-weave appearance, large and clear blue-gray keratinocytes with finely granular cytoplasm and vacuolized nuclei, and abundant keratohyaline granules located in the upper epidermal layer (Fig. 3). Scrotum biopsy showed hyperkeratosis, irregular acanthosis with papillomatosis, and koilocytic figures. The genital lesions were treated with monthly cryotherapy plus surgical excision with complete disappearance of the lesions. A decrease in ultraviolet exposure and daily sun-block were encouraged for epidermodysplasia verruciformis lesions. After genital wart clearance, follow-ups are being scheduled every 4 months, with no new lesions to date.

Abstract
Foci of histological changes of epidermodysplasia verruciformis (EV) were noted in five benign skin lesions. These skin lesions included an intradermal nevus, a pigmented seborrheic keratosis, an isolated papule on the forearm, a perianal lesion, and an acantholytic acanthoma. Because the changes resembled true EV so strongly despite the absence of clinical EV in these patients, we searched for EV-human papilloma virus (HPV) types in these skin lesions. Polymerase chain reaction (PCR) analysis on the formalin-fixed, paraffin-embedded blocks was performed. As a positive control, we included tissue from two HIV-positive patients with clinical EV proven by biopsy. Studies were also performed on five other archived biopsies that did not show changes of EV on multiple tissue sections. A nested PCR method detected EV-HPV types in three of the five benign skin lesions showing EV changes as well as in the positive controls. EV changes and EV-HPV can be found incidentally on biopsy in the absence of clinical EV; when such changes are the major histopathological finding in an isolated skin lesion, the lesion should be termed an EV acanthoma.

Abstract
Epidermodysplasia verruciformis (EV) is a rare human genetic predisposition to develop flat warts, some of which subsequently undergo cancer transformation. Some human papillomaviruses (HPVs), i.e. HPV 5 and 8, have been associated with cancer development as a sequela of EV. As similar diseases have been observed in dogs, it was hypothesized that unknown canine papillomaviruses (CPVs) may exist and that they may be present in cases of canine EV. Consequently, DNA was extracted from a malignant lesion of a dog with EV and circular DNA was amplified by multiple-primed rolling-circle amplification (RCA). Indeed, sequence determination and analysis of the RCA-amplified and cloned DNA from a malignant canine EV lesion resulted in the detection and primary description of a third CPV (CPV3). Typical papillomavirus genes were identified, with deduced amino acid similarities ranging from 20 to 57 % for E1, E2, E6, E7, L1 and L2, respectively. According to the sequence of the L1 gene, which is used for papillomavirus classification, the new isolate meets the majority of criteria needed to declare detection of a novel genus among the papillomaviruses. Thus, CPV3 may represent the prototype of this novel genus. As the novel virus was found in a dog in association with lesions reminiscent of human EV, it should be interesting to test in the future whether this condition can be reproduced in experimental animals. If such were the case, a new model for EV could be established.

Abstract
Human papillomavirus type 8 (HPV8) poses a high risk for malignant conversion of skin lesions in patients with Epidermodysplasia verruciformis (Ev). Its oncogene promoter P(175) contains the conserved sequence motifs CCAAC, M29, and an A/T-rich region, which are common in many Ev-associated viruses. In human keratinocytes P(175) shows very weak activity. We used the M29 sequence as bait in a yeast-one-hybrid screen of a HaCaT cDNA library to identify interacting proteins regulating P(175). We report the identification of a cDNA encoding the interferon regulatory factor IRF5.2. In band shift assays the physical interaction of IRF5.2 and M29 was confirmed, and also its binding to the negative regulatory element (NRE) of HPV8 could be demonstrated. In transient reporter gene assays, overexpressed IRF5.2 acts as a transcriptional repressor of HPV8 and the Ev-associated HPV types 5, 14, and 25. These results indicate that the cellular transcription factor IRF5.2 is a general transcription repressor of Ev-associated HPV.

Abstract
We report a patient with epidermodysplasia verruciformis (EV) who had severe generalized verrucous skin lesions for 50 years without any immunological abnormality. Microscopic examination showed two histopathological features, including seborrhoeic keratosis and common warts. The detected human papilloma virus (HPV) types were found to be HPV 3, 50, 5, and 76, using a degenerate PCR method. EV and generalized verrucosis are distinguished by slight differences in clinical symptoms or HPV types, so there should be no apparent differential points common to both diseases. Therefore, we propose that an abnormal susceptibility specific to HPV, which is the most characteristic feature in EV, should be regarded as a differential point in these two diseases.

Abstract
Human papillomaviruses (HPVs) are DNA tumour viruses that induce hyperproliferative lesions in cutaneous and mucosal epithelia. The relationship between HPV and non-melanoma skin cancer (NMSC) is important clinically since NMSC is the most common form of malignancy among fair-skinned populations. It is well established that solar ultraviolet (UV) irradiation is the major risk factor for developing NMSC, but a pathogenic role for HPV in the development of NMSC has also been proposed. Recent molecular studies reveal a likely role for HPV infection in skin carcinogenesis as a co-factor in association with UV. This review summarizes the literature describing these data, highlights some of the important findings derived from these studies, and speculates on future perspectives.

Abstract
Epidermodysplasia verruciformis (EV)-type human papillomavirus (HPV) DNA have been detected by PCR in squamous cell carcinomas (SCC) from both organ transplant recipients (OTR) and immunocompetent individuals. Their role in skin cancer remains unclear, and previous studies have not addressed whether the viruses are transcriptionally active. We have used in situ hybridization to investigate the transcriptional activity and DNA localization of HPV. EV-HPV gene transcripts were demonstrated in four of 11 (36%) OTR SCC, one of two (50%) IC SCC, and one of five (20%) OTR warts positive by PCR. Viral DNA co-localized with E2/E4 early region gene transcripts in the middle or upper epidermal layers. Non-EV cutaneous HPV gene transcripts were demonstrated in one of five (20%) OTR SCC and four of 10 (40%) OTR warts. In mixed infections transcripts for both types were detected in two of six (33%) cases. Our results provide evidence of EV-HPV gene expression in SCC; although only a proportion of tumors were positive, the similarly low transcriptional activity in warts suggests this is an underestimate. These observations, together with emerging epidemiological and functional data, provide further reason to focus on the contribution of EV-HPV types to the pathogenesis of cutaneous SCC.

Abstract
BACKGROUND Epidermodysplasia verruciformis (EV) is a rare disorder characterized by widespread flat and common verrucae. From 25% to 50% of EV cases are inherited, usually with an autosomal recessive pattern. An X-linked inheritance has also been reported. Many EV patients have a cellular immunity defect. HIV-associated lesions have been found to contain HPV-5, HPV-8, and HPV-20. OBJECTIVE We describe two HIV-positive Hispanic maternal half brothers who presented with asymptomatic polyangular papules and plaques on the face, trunk, and extremities and which first appeared 4-5 years prior. The histopathology is consistent with EV. HPV-8 was detected by in situ hybridization. The patients were treated with topical imiquimod for two months without improvement. CONCLUSION To our knowledge, this is the first reported case of epidermodysplasia verruciformis in HIV-positive pediatric patients.

Abstract
BACKGROUND DNA of epidermodysplasia verruciformis (EV)-associated human papillomaviruses (HPVs) has been widely detected in lesions of malignant skin tumours, benign tumours and other proliferative diseases of epithelial origin. OBJECTIVES To investigate the presence of EV-associated HPV DNA in nongenital seborrhoeic keratosis (SK) and to elucidate the prevalence of distinct HPV genotypes. METHODS We investigated HPV DNA in 55 nongenital SK biopsies, which were compared with 48 normal skin biopsies (healthy controls) using a nested polymerase chain reaction (PCR) using consensus primers CP65/CP70 and CP66/CP69. The positive PCR products were retracted and used to prepare recombination clones with T-vector. Distinct clones were analysed with endonucleases, and HPV genotypes were identified by direct sequencing. RESULTS EV-associated HPV DNA was detected in 42 of 55 (76%) nongenital SK biopsies vs. only 13 of 48 (27%) healthy controls (chi2 = 22.087; P < 0.005). The prevalence was higher in patients with more than five lesions than in those with only one lesion (P < 0.05). Ten distinct HPV genotypes were detected in the nongenital SK biopsies: HPV 20, 23, 5, renal transplant recipient (RTR) X7, HPV 17, 37, 17b, RTRX4, RTRX4b and strain SK3. HPV 20 was found in 26 of 42 (62%) positive specimens, followed by HPV 23 (11 of 42, 26%) and HPV 5 (six of 42, 14%). Existence of multiple HPV genotypes was observed in 12 of 42 (29%) positive specimens. In healthy controls, five genotypes of EV-associated HPV (HPV 20, 23, 5, 17 and RTRX4) were detected, with the same predominant genotype of HPV 20 (five of 13, 38%). Several distinct HPV genotypes were found to coexist in four of 13 (31%) positive specimens. CONCLUSIONS This study provides some evidence that EV-associated HPVs might play a part in the pathogenesis of nongenital SK.

Abstract
BACKGROUND Mucosal high-risk human papillomaviruses (HPVs), such as type 16, are detectable in oral cancers, especially of the oropharynx and tonsils, and there is evidence that they play a pathogenetic role in some cases. However, information is limited about their significance for cancers of the vermilion of the lip. OBJECTIVE To determine the detection rate, types and localization of HPVs in squamous cell carcinomas (SCCs) of the lip. METHODS Nested PCR for cutaneous HPVs, including epidermodysplasia verruciformis-related HPV (EV-HPV), and single PCR for mucosal HPVs, were conducted for a total of 27 SCCs and normal samples from 30 individuals. Tyramide-based in situ hybridization (ISH) was also applied. RESULTS Various types of HPVs were detected, particularly from normal individuals. Among the kinds of the HPV types detected in this study, half were found by PCR using a primer pair, which we newly designed. The prevalence of HPV was 5 out of 27 SCCs (ca. 18%) and 10 out of 30 normal individuals (ca. 33%). They were the entire cutaneous-group except for two, from one SCC and one normal individual. CONCLUSION On the surface of the normal lip various types of mainly cutaneous-group HPVs may be present, but there does not appear to be any obvious association with SCCs developing in this site.

Abstract
Cutaneous epidermodysplasia verruciformis (EV)-associated human papillomaviruses (HPVs) are found frequently in skin cancers especially in immunosuppressed people. They are also detectable in the normal skin and hair follicles of a proportion of individuals who have no immune defect. The available evidence to link HPVs causally with skin carcinogenesis is not conclusive, but includes epidemiological, molecular and immunological studies.

Abstract
Ultraviolet radiation (UVR) is associated with an increased risk of squamous cell carcinoma (SCC), which is in part due to immunomodulation. In addition, human papilloma virus (HPV), especially the epidermodysplasia verruciformis (EV)-associated types, may be involved. In view of the capacity of UVR to impair host resistance to infections, we investigated the relationship between solar exposure and the prevalence of cutaneous HPV. In a case-control study on skin cancer (320 controls and 156 patients) a lifetime-retrospective questionnaire on sun exposure was administered. The presence of DNA of HPV types 5, 8, 15, 20, 24, and 38 in plucked eyebrow hair and type-specific seroreactivity were assessed and analyzed in relation to estimated exposure. Sunburn episodes in the past, especially at age 13-20 y, appeared to be associated with an enhanced risk of EV-HPV DNA positivity. In contrast, a higher lifetime sun exposure was associated with a lower risk of HPV infection. These results indicate that UVR at erythematogenic doses increases the risk of EV-HPV infection, possibly due to impaired host resistance to HPV and/or a direct effect of UVR on viral replication. The favorable association between lifetime sun exposure and HPV prevalence, however, underscores the enigmatic role of HPV in skin carcinogenesis.

Abstract
BACKGROUND Epidermodysplasia verruciformis is a rare genetic disorder characterized by development of lesions associated with HPV#5 or HPV#8 in early childhood; malignant transformation occurs in approximately half of individuals during adulthood. OBJECTIVE Our goal was to study the presence and spectrum of EV-HPV types in Brazilian EV patients, a population that had never been studied in this regard. PATIENTS AND METHODS Forty-one biopsies from different lesions (benign and skin tumors) and one biopsy from clinically normal skin from each of 20 Brazilian patients with EV were studied for HPV typing using nested PCR. RESULTS EV-HPV DNA was detected in all 41 skin lesions of the patients and was also identified in specimens considered as normal skin from 8 patients (40%). In this study HPV-EV 25 was the most prevalent (70%), and HPV 14d (67%) was highly associated with malignant lesions. CONCLUSION EV-HPV 25 was the most prevalent in our study. The noteworthy association of EV-HPV type 14d with skin cancers suggests its possible oncogenic role in malignant transformation in this population.

Abstract
BACKGROUND Human papillomaviruses (HPVs) are found in normal skin and in benign and malignant skin conditions. Epidermodysplasia verruciformis (EV) HPV types are those most plausibly linked to the development of squamous cell carcinomas of the skin. OBJECTIVES To assess the risk of nonmelanoma skin cancer (NMSC) associated with the presence of EV HPV in normal skin in immunocompetent (IC) individuals and renal transplant recipients (RTRs). METHODS Using a degenerate and nested polymerase chain reaction technique, HPV DNA was sought in 124 normal skin samples from sun-exposed and nonsun-exposed sites, from 39 IC individuals and 38 RTRs, both with and without NMSC. Data were analysed using the Mantel-Haenszel test and by logistic regression analysis. RESULTS HPV DNA was detected in 58/67 (87%) and 20/57 (35%) samples from renal transplant and IC patients, respectively. There was no difference in either the prevalence or spectrum of HPV types found in sun-exposed and nonsun-exposed normal skin. However, there was significant association between NMSC and the presence of EV HPV DNA. Multivariate analysis provided an odds ratio of 6.41 (95% confidence interval 1.79-22.9) for the association of EV HPV DNA in normal skin (irrespective of site) and NMSC status, even after stratifying for patient group and adjusting for the clustering effect of multiple sampling. Conversely, there was no association between skin cancer status and the presence of cutaneous or mucosal HPV types in either sun-exposed or nonsun-exposed skin. CONCLUSIONS HPV DNA is widespread in normal adult skin, particularly in transplant patients. In our study, the presence of EV but not cutaneous HPV DNA in normal skin was significantly associated with NMSC status and may prove to be of predictive value for skin cancer risk. These data provide reason to focus on EV HPV types as causal agents in skin cancer.

Abstract
The aim of the present study was to characterise natural cell-mediated cytotoxicity against COS-7 cells transfected with potentially oncogenic HPV-8 L1 DNA sequences cloned in sense and antisense orientation and to evaluate their lysis by peripheral blood lymphocytes (PBL) from patients with epidermodysplasia verruciformis (EV), a rare disease associated with life-long infection by specific HPV types. COS-7 cells were transfected with HPV-8 Hinc II restriction fragment (nucleotide positions 5434-7654) cloned in sense (COS-L1S) and antisense (COS-L1A) orientation into pCB6 expression vector. Cytotoxic activity of isolated PBL against COS cell lines as well as K562 erythroleukaemic cells was evaluated by 51Cr-release assay. We found that lymphocytes responsible for natural lysis of COS and K562 cells are CD3-negative CD56-positive natural killer (NK) cells. Analysis of NK cell cytotoxic activity against different COS cell lines has revealed that lymphocytes from healthy subjects killed COS-L1S cells significantly more efficiently than wild COS-7 and COS-L1A cells. Significantly more efficient lysis of COS-L1S cells was also observed in EV patients. Thus, expression of HPV L1 renders target cells more susceptible to NK-mediated cytotoxicity that may enable more effective elimination of transformed cells.

Abstract
BACKGROUND Psoriasis is a T-cell-mediated immunological disease characterized by epidermal proliferation. The nature of the antigen(s) responsible for T-cell activation is still unknown. It has been suggested that the human papillomaviruses (HPVs) associated with epidermodysplasia verruciformis (EV), including the oncogenic HPV5, may contribute to the pathogenesis of psoriasis. OBJECTIVES To determine whether EV-HPVs may play a role early in the disease, we searched for these viruses in children with psoriasis. The influence of clinical data on EV-HPV infection was investigated. METHODS We studied scrapings of involved skin from 26 children aged 1.5-13 years with psoriasis. As controls, we analysed scrapings from 28 adults with psoriasis and 15 children with atopic dermatitis, as well as scrapings from normal skin of 28 adults with no known history of HPV infection. We searched for EV-HPV DNA sequences with a nested polymerase chain reaction method using degenerate primers specific for EV-HPVs and primers specific for HPV5 and HPV36, two EV-HPVs frequently detected in adults with psoriasis. RESULTS Similar high prevalences were observed in children and adults with psoriasis for EV-HPVs (38.5% vs. 35.7%), HPV5 (46.2% vs. 46.4%) and HPV36 (15.4% vs. 25.0%). As in adults, we found several EV-HPV genotypes and HPV5 and HPV36 variants. A novel HPV36 subtype, HPV36b, was identified. Lower prevalences were observed in children with atopic dermatitis and in adults from the general population (6.7-10.1%). No correlation was observed between frequency of detection of HPVs and clinical data. It is noteworthy that HPV5 was identified in an 18-month-old girl and in a boy with psoriasis developing for only 1 week. CONCLUSIONS The early detection of several EV-HPV genotypes in children further supports the link between psoriasis and EV-HPVs and suggests a putative role for these viruses in the pathogenesis of psoriasis.

Abstract
Skin cancers in both immunosuppressed and immunocompetent populations are associated with epidermodysplasia verruciformis human papillomavirus (EV-HPV) DNA. However, little is known about the prevalence of EV-HPVs in actinic keratoses in immunocompetent individuals. Actinic keratoses from 114 patients were classified as low-grade ( n=76) or high-grade ( n=38) according to the extent of histological atypia. HPV DNA was amplified from 54 frozen and 60 paraffin-embedded biopsy specimens by nested polymerase chain reaction (PCR) with several consensus and type-specific primers. PCR products were sequenced for typing. These results were compared with HPV detection in skin cancers ( n=20) and Bowen's disease ( n=18). A broad spectrum of EV-HPV types including oncogenic HPV5 and HPV8 and partially characterized sequences were detected in actinic keratoses and cutaneous cancers. In actinic keratoses a higher prevalence of EV-HPV DNA was found in frozen tissues than in formalin-fixed tissues (85% vs 67%). There was no difference between the low- and high-grade actinic keratoses either in terms of EV-HPV DNA prevalence or the results of serological study using HPV8 virus-like particles. The detection rate of EV-HPVs was lower in skin cancers and Bowen's disease. This would suggest involvement of EV-HPVs in the early stages of cutaneous oncogenesis.
