Abstract
BACKGROUND Epidermodysplasia verruciformis (EDV) is a rare cutaneous manifestation of human papilloma virus infection, which has a potential for malignant transformation. The characteristic histologic features of EDV may not always be present and may often be overlooked. The use of a panel of novel biomarkers may aid in differentiating EDV from their clinical and pathologic mimics. MATERIAL AND METHODS We reviewed 20 cases histologically diagnosed as EDV from 2013 to 2022. Sections were reviewed for histopathologic features, and immunohistochemistry for p16 and Ki67 was performed. RESULTS There were 20 cases, ranging in age from 6 to 52 years with a male predominance. Four patients were immunosuppressed, and 4 patients had a positive family history. The most common presentation was hypopigmented papules and macules. In all the cases, epidermal keratinocytes showed dysmaturation, enlargement, and a blue-gray cytoplasm. These changes were very focal and superficial in 15 cases (75%). Associated malignancies included carcinoma in situ (1), trichilemmoma (2), and trichilemmal carcinoma (1). The trichilemmal tumors were seen in 2 siblings. p16 was expressed in the parabasal and basal layers in 7 of 17 cases (41%), in keratinocytes with and without inclusions. Ki67 was increased and localized to suprabasal and parabasal keratinocytes in 15 of 17 cases (88%). CONCLUSION Although striking and characteristic, the keratinocyte changes are often focal and superficial, requiring multiple step-sections. Association of EDV with familial trichilemmal neoplasms is a novel finding requiring further genetic testing. In cases of clinically suspected EDV with negative histopathologic findings, p16 and Ki67 seem useful as adjunct biomarkers and could serve as cost-effective alternatives to genotyping.

Abstract
ABSTRACT Human papilloma virus (HPV) is the causative agent for a variety of cutaneous lesions including verruca vulgaris (VV) and epidermodysplasia verruciformis (EDV). There are more than 200 known genotypes of HPV, and specific HPV types are associated with different clinical manifestations and malignant potentials. Herein, we describe a case of a 43-year-old immunocompetent woman who presented with morphologically distinct lesions that were most consistent with EDV on clinical examination. However, further histopathological and viral analysis confirmed the lesions as HPV-57-positive VV. The risk of malignant transformation, and therefore treatment and surveillance, is dramatically different in VV versus EDV. Therefore, this case highlights the importance of a proper histopathological diagnosis with HPV viral testing when clinical presentations may vary or mimic other diseases.

Abstract
Acquired epidermodysplasia verruciformis (AEV) is a form of epidermodysplasia verruciformis (EV) that is most commonly found in immunocompromised or immunosuppressed patients. EV is commonly associated with human papillomavirus (HPV), which is often found in EV and AEV lesions. Clinical presentation of AEV in patients with organ transplantation, HIV+, congenital HIV+, hematological diseases, and other iatrogenic immunosuppression are reviewed. Treatment options include topical cidofovir, topical retinoids, topical imiquimod, topical glycolic acid, HPV 9-valent vaccine, acitretin, improving cellular immunity, and changing transplant medication to mycophenolate mofetil.

Abstract
ABSTRACT Epidermodysplasia verruciformis (EV) is a rare dermatologic condition that is clinically characterized by flat, cutaneous, verrucous papules, pityriasis versicolor-like lesions, and similar lichenoid papules. There are 2 forms of EV: a classic inherited genodermatosis and a secondary acquired form. EV predisposes individuals to infections with certain types of human papillomavirus virus and subsequently increases the risk of cutaneous squamous cell carcinoma. The acquired form occurs in immunosuppressed patients, particularly in patients infected with HIV; however, it has also been described in patients who have undergone stem cell and solid organ transplantation. We report an additional case of renal transplantation and immunosuppressive therapy-associated acquired EV (AEV) in a 78-year-old man with multiple flesh-colored to violaceous, flat-topped papules distributed on the face and trunk clinically mimicking lichen planus. Biopsy was typical for that of EV, demonstrating enlarged keratinocytes with a blue-gray cytoplasm, a thickened granular layer, acanthosis, and hyperkeratosis. Herein, we discuss an unusual presentation of an AEV-mimicking lichen planus with review of the literature.

Abstract
Antiretroviral therapy (ART) has revolutionized the treatment and prognosis of people living with HIV (PLHIV). With increased survival and improved overall health, PLHIV are experiencing dermatologic issues both specific to HIV and common to the general population. In this new era of ART, it is crucial for dermatologists to have a strong understanding of the broad range of cutaneous disease and treatment options in this unique population. In this review, we outline the most common skin diseases in PLHIV, including HIV-associated malignancies, inflammatory conditions, and infections, and focus on the role of ART in altering epidemiology, clinical features, diagnosis, and treatment of cutaneous conditions.

A comparison of the detection of biomarkers in infections due to low risk versus high-risk human papillomavirus types. Ann Diagn Pathol 2019; 41:57-61.

Abstract
Adjunctive immunohistochemistry tests for human papillomavirus (HPV) infection include p16 and Ki67 as well as the more recently discovered biomarkers importin-β, exportin-5, Mcl1, and PDL1. The purpose of this study was to compare the expression of these biomarkers in HPV infection due to the high-risk types such as HPVs 16, 18, 31, 33, 35, and 51 versus lesions that contain the low risk types HPV 2, 6 or 11. We studied 35 lesions with low risk HPV types (verruca vulgaris = 10 cases, condyloma acuminatum = 15 cases, CIN 1 with HPV 6/11 = 10 cases) and 25 CIN 1 or 2 lesions with a high-risk HPV type. The 25 high-risk positive CIN 1-2 cases had strong expression of the panel p16, Ki67, importin-β, exportin-5, Mcl1, and PDL1 where each protein localized to the cells in the parabasal aspect of the lesion. In comparison, neither p16, importin-β, exportin-5, Mcl1, nor PDL1 were increased in the epithelia of the lesions with the low risk HPV types; Ki67 showed variable expression. HPV viral capsid L1 protein and viral DNA were excellent markers of infection in the lesions with low risk types. Thus, p16, importin-β, exportin-5, Mcl1, and PDL1 are not only biomarkers of high-risk HPV infection but can also differentiate such lesions from those that contain low risk HPV types. Low risk HPV infections can be best differentiated from their mimics by viral L1 capsid detection and/or HPV DNA by in situ hybridization.

Abstract
The cause of epidermodysplasia verruciformis is infection by human papillomavirus, usually types 5 or 8, and it exhibits a high potential for malignant transformation. The diagnostic histologic features of epidermodysplasia verruciformis are not always present and can be mimicked by non-viral diseases. The purpose of this study was to interrogate such lesions for new potential biomarkers to aid in the diagnostic accuracy. HPV DNA was high copy and localized to the upper half of the lesion in cells with cytologic features that included perinuclear halos, blue-grey cytoplasm, and hyper/parakeratosis. Serial section analyses demonstrated that there was increased expression of importin-β, exportin-5, Mcl1, p16, Ki67 and PDL1 in 13/13 epidermodysplasia verruciformis lesions. Each of these proteins localized primarily to the less differentiated cells in the parabasal aspect of the lesion. Only Ki67 and exportin-5 were expressed in the normal epithelia, though much less so, in 13/13 aged matched controls. It is concluded that the host response to HPV 5/8 infection in epidermodysplasia verruciformis includes the up regulation of several proteins including p16, Ki67, importin-β, exportin-5, Mcl1, and PDL1. Thus, these proteins may serve as new biomarkers of this disease that can aid in cases that are equivocal for epidermodysplasia verruciformis on histologic examination.

Abstract
Epidermodysplasia verruciformis (EV) is a rare skin disease characterized by the development of multiple flat warts with the potential for malignant transformation. Patients are susceptible to human papillomavirus (HPV) infection that develops in a background of either a genetic or acquired immunodeficiency predisposing patients to infection with specific HPV types that are ubiquitous but generally non-pathogenic in healthy individuals. There is no standard clinical methodology for determining the causative HPV from patients with suspected EV. Here, we report the diagnostic workup of two EV cases and describe the use of L1 gene Sanger sequencing as a specific method to accurately identify the causative HPV genotype and confirm the diagnosis of EV.

Abstract
The vast majority of vulvar human papilloma virus infections are produced by α human papilloma viruses and consist of exophytic or flat warts and classic or "usual" vulvar intraepithelial neoplasia. This report details 2 examples of epidermodysplasia verruciformis-like lesions of the vulva in women who were immunosuppressed. The most consistent morphologic feature was the presence of abnormal mature keratinocytes with large pale open nuclei with small nucleoli and eosinophilic cytoplasm, situated in the upper epithelial layers. In addition to these features, which are commonly seen in epidermodysplasia verruciformis-associated lesions, 1 case displayed in addition more extensively distributed abnormal nuclei, including involvement of both the upper epithelial strata and the epithelial/stromal interface. Both lesions were associated with β-papilloma virus type 5. The unique aspects of epidermodysplasia verruciformis-like lesions relative to the more common human papilloma virus infections of the vulva are highlighted and these cases illustrate the range of epithelial distribution that might be encountered in lesions involving the vulvar mucosa.

Abstract
A 75-year-old man with human immunodeficiency virus infection and numerous biopsy-proven warts for 10 years, refractory to cryosurgery, cimetidine, and topical imiquimod, presented with numerous pink to hypopigmented verrucous papules and plaques involving the face, trunk, buttocks, and groin. Laboratory evaluation revealed a CD4 T-cell count of 62 cells per microliter and human immunodeficiency virus viral load of <117 copies per milliliter. Biopsy of a plaque groin lesion was performed. Histopathology revealed vertically oriented anastomosing strands of basaloid epithelium arising from multiple points along the epidermis in a background fibrovascular stroma. Ductal differentiation was identified. Areas of epidermis showed compact orthokeratosis, coarse hypergranulosis, and keratinocytes with abundant steel-blue-gray cytoplasm, indicative of viral cytopathic changes. Cytologic atypia was not identified. Human papillomavirus (HPV) genotyping of this lesion was positive for types 5 and 14. Overall, the findings were consistent with epidermodysplasia verruciformis in association with eccrine syringofibroadenoma (ESFA). The patient was subsequently treated with acitretin and showed clinical improvement. ESFA is an uncommon benign adnexal tumor with unknown pathogenesis. Although its association with HPV has rarely been reported, ESFA in the setting of acquired epidermodysplasia verruciformis has not been described. The development of ESFA in this case may be the result of HPV-induced cellular transformation.

Abstract
Elephantiasis is considered a cutaneous region of immune deficiency with cobblestone-like surface caused by a wart-like eruption. Verrucosis is a diffuse human papillomavirus (HPV) infection linked to immunodeficiency disorders. The objective of this study was to examine the prevalence of HPV infection in lymphedema and its pathogenic role in elephantiasis. A retrospective case-control study was performed examining lymphedematous skin and controls of peritumoral normal skin. HPV infection was evaluated at the DNA, protein, and histopathologic levels by polymerase chain reaction, immunohistochemistry, and light microscopy, respectively. Overall, 540 HPV DNAs were detected in 120 of 122 cutaneous samples (median 4 HPV DNAs per sample, range 0-9). Compared with controls, no differences existed in type or number of HPVs identified. Instead, a diverse spectrum of HPV-related histopathologies were evident, likely reflecting the multiplicity of HPV genotypes detected. Most notably, increasing histopathologic lymphedema stage significantly correlated with markers of productive HPV infection such as altered keratohyaline granules and HPV L1 capsid expression. Limitations of this study are the absence of normal skin controls not associated with neoplasia or subclinical lymphedema, and lack of assessment of HPV copy number per keratinocyte infected. In conclusion, productive HPV infection, not HPV type or numbers detected, distinguished lymphedematous skin from controls. These findings support the theory that lymphedema creates a region of depressed immunity that permits productive HPV infection, manifested clinically by diffuse papillomatosis, characteristic of elephantiasis.

Abstract
Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by abnormal susceptibility to cutaneous human beta-papillomavirus infections causing persistent flat warts or pityriasis versicolor-like lesions. This generalized verrucous skin disorder resembles generalized verrucosis, but these 2 conditions are distinguished by differences in clinical manifestation and the human papillomavirus types involved. A breakthrough in our understanding of EV was the discovery that homozygous inactivating mutations in TMC6 (EVER1) and TMC8 (EVER2) determine susceptibility to this disorder; however, they have not solved all EV cases fully. These deficiencies account for 75% of affected individuals, leaving a substantial number of patients without an underlying genetic cause. Recently, it has been revealed that mutations in additional genes (RHOH, MST-1, CORO1A, and IL-7) result in extensive human beta-papillomavirus replication and therefore manifest with an EV-like phenotype. The term "acquired EV" is used to describe an EV-like phenotype that develops in immunocompromised hosts, and the introduction of this entity further aggravates the confusion. Reevaluation of these entities is warranted. Here, we review the available data on this issue, provide up to date information on the major characteristics that differentiate between these seemingly clinically similar disorders, and highlight the different mechanisms involved in each disorder.

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
Epidermodysplasia verruciformis (EV) is an uncommon inherited skin condition with increased vulnerability to widespread infection by certain human papillomavirus types, resulting in extensive verruca plana-like papules coalescing to large confluent plaques. Since the AIDS epidemic starting in the 1980s, an acquired type of EV has been described in patients infected with human immunodeficiency virus. The histopathologic features of EV consist of papillated epidermal hyperplasia with hypergranulosis and a distinct bluish-gray color in the large human papillomavirus-infected keratinocytes in the stratum granulosum. The authors present a case of HIV-associated EV with a unique histopathologic finding of multiple cornoid lamella-like structures. To the authors' knowledge, this finding has not been previously described in the literature.

Abstract
Herein, we report the case of a 12-year-old female who noted the recent onset of an oval, circumscribed, 10-cm papillomatous plaque affecting the thigh and vulva that showed histologic signs of lymphedema without evidence of secondary lymphedema. The sequencing of genes associated with a delayed onset of lymphedema or epidermal nevi (EN) - GATA2 and GJC2, and HRAS and KRAS, respectively - showed wild-type alleles. Polymerase chain reaction for human papillomavirus (HPV) DNA demonstrated infections with 15 HPV genotypes. Evidence of productive HPV infection, HPV capsid expression, and cytopathic changes was detected. At the 6-month follow-up, no evidence of recurrence was found after complete excision. The analysis of a consecutive series of 91 EN excision specimens revealed that 76% exhibited histologic evidence of lymphostasis. Notably, multiple acrochordon-like EN, which most closely resembled this case, showed similar signs of localized lymphedema. The late onset and evidence of lymphedema favors the diagnosis of congenital unisegmental lymphedema. However, the clinical findings and epidermal changes point to the diagnosis of EN. Moreover, localized verrucosis also accurately describes this patient's cutaneous findings. Based on the above evidence, we postulate that an abnormal development of lymphatics may play a primary role in the pathogenesis of some types of EN and facilitate productive HPV infection.

Persistent toenail onycholysis associated with Beta-papillomavirus infection of the nail bed. Am J Dermatopathol 2014; 37:329-33.

Abstract
Onycholysis, separation of the nail plate from the nail bed, is etiologically classified as primary (idiopathic) or secondary (eg, caused by psoriasis, squamous cell carcinoma). Repetitive microtrauma plays a role in idiopathic onycholysis and also facilitates human papillomavirus (HPV) infection. Herein, we report a case of persistent primary onycholysis associated with repetitive trauma and infection by a multiplicity of Beta-papillomavirus (Beta-PV) genotypes. An otherwise healthy 27-year-old woman presented with a 6-year history of onycholysis of the halluces and right second toe. Her occupation required wearing steel-toed boots. Fungal cultures were negative and antifungal therapy was ineffective. Punch biopsy of the hallux nail bed revealed epidermal hyperplasia, acanthosis, hypergranulosis, hyperkeratosis, and regions of koilocytosis without significant inflammation. This histopathology implicated chronic irritation and HPV infection. Immunohistochemistry demonstrated productive HPV infection. Nested PCR using degenerate consensus primers revealed infection with 5 known and 1 novel Beta-PV genotypes (HPV 5, HPV 8, HPV 20, HPV 23, HPV 37, and FA25). The histopathology of primary onycholysis is unknown. Based on the aforementioned, we propose that repetitive microtrauma caused by wearing steel-toed boots promoted onycholysis and HPV infection, the latter of which, altered the differentiation of nail bed epithelium, preventing adhesion of nail plate to the nail bed. Lastly, the presence of oncogenic Beta-PV genotypes (ie, HPV 5, 8, and 20) implicates a risk for subungual squamous cell carcinoma, particularly if the nail remains symptomatic and persistently irritated.

Abstract
Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by increased sensitivity to infection by the β-subtype of human papillomaviruses (β-HPVs), causing persistent, tinea versicolor-like dermal lesions. In a majority of affected individuals, these macular lesions progress to invasive cutaneous squamous cell carcinoma (CSCC) in sun-exposed areas. While mutations in transmembrane channel-like 6 (TMC6 / EVER1) and 8 (TMC8 / EVER2) have been causally linked to EV, their molecular functions are unclear. It is likely that their protective effects involve regulation of the β-HPV life cycle, host keratinocyte apoptosis vs. survival balance and/or T-cell interaction with infected host cells.

Abstract
Epidermodysplasia verruciformis (EDV) is a rare genodermatosis characterized by susceptibility to human papilloma virus (HPV) infection. An acquired form of EDV has been described in the setting of immunosuppression, including in patients with the human immunodeficiency virus (HIV). We present the case of an HIV-positive, adopted Haitian boy who presented with EDV. Few cases of chidren with HIV and acquired EDV have been reported and are likely underrecognized.

Abstract
For humans, strong evidence indicates that some mucosal papillomavirus (PV) types cause genital and oral neoplasia, and weaker evidence suggests that some cutaneous PVs may cause cutaneous squamous cell carcinomas (SCC). For nonhuman species, strong evidence supports a causal role of PVs in the development of feline and equine sarcoids. Likewise, PVs are believed to cause cutaneous SCCs in rabbits, western barred bandicoots, and some rodents. Furthermore, some evidence suggests that PVs may influence the development of both feline and canine cutaneous SCCs. This review discusses the evidence that PVs cause human cutaneous SCCs and the proposed mechanisms for this action. It then reviews preneoplastic and neoplastic skin diseases that are associated with PV infection in nonhuman mammals.

Abstract
BACKGROUND The hamartoma nevus sebaceus (NS) presents at birth or early childhood as a yellowish plaque characterized histologically by variable acanthosis, papillomatosis, sebaceus hyperplasia, and proliferations of adnexal structures. Clinically apparent human papillomavirus (HPV) infection is also recognized by acanthosis and papillomatosis. OBJECTIVE We sought to determine the prevalence and physical state of HPV DNA in NS. METHODS DNA was retrieved from 44 formalin-fixed, paraffin-embedded samples of NS (22 with secondary tumors [eg, trichoblastoma, verruca, syringocystadenoma papilliferum] and two epidermal nevi [EN]). Nested polymerase chain reaction with multiple degenerate consensus and type-specific primers and direct sequencing of polymerase chain reaction products was performed. For selected cases, in situ hybridization using probes specific for HPV 5 and 8 and for high-risk genital-mucosal HPV types was performed. RESULTS HPV DNA was detected in 82% of NS and both EN, and consisted of genital-mucosal HPV types in 52% (HPV 6, 16, and 33) and a diverse variety of epidermodysplasia verruciformis-associated HPV types in 61%, including well-known epidermodysplasia verruciformis HPV types (5, 8, 15, 20, 22, 24, 36, 37, 38, and 80) and putatively novel epidermodysplasia verruciformis HPV types (DL285, DL287, DL436, and alb-1, -2, -3, -5, -6, -7, -8, -10, -11, -12, and -13). HPV coinfection was frequent, found in 48% (two HPV genotypes in 35% and 3 in 13%). Of NS and EN, 42% had HPV genotypes associated with cancer (ie, HPV 5, 8, 16, 20, 33, and 38); the two most commonly identified HPV types where HPV 16 (39%) and HPV 38 (18%). No differences were detected comparing frequency of HPV DNA detected with respect to age or presence of a secondary tumor. Histologically, all NS and EN showed HPV-associated cytopathic effects (ie, perinuclear halos, altered keratohyaline granules). By in situ hybridization, 64% (18/28) were positive, showing a low-intensity, punctate nuclear signal in epidermal and adnexal keratinocytes, indicating viral integration and low viral genome copy number. LIMITATIONS Absence of adjacent, uninvolved normal-appearing skin control samples. CONCLUSION HPV DNA is prevalent in NS, and HPV 16, the most frequently detected genotype, appears to be integrated into the host genome. Whether HPV represents a commensal infection caused by localized cutaneous predisposition, or is an essential factor in the pathogenesis of NS is unknown. The high frequency of oncogenic HPV types implicates maternal transmission of HPV and infection of an ectodermal stem cell leading to an epigenetic mosaic and altered skin development manifested along Blaschko's lines.

Abstract
Vulvovaginal melanomas are rare and their etiology is unknown. Genital mucosal human papillomavirus (HPV) 16 has been identified in both cutaneous and mucosal melanoma, suggesting that it might play a role in the pathogenesis or progression of melanoma. In this study, we investigated the prevalence of HPV DNA by using a broad spectrum of degenerate and type-specific primers for genital-mucosal, epidermodysplasia verruciformis-associated (EV), and cutaneous HPV types in 6 vulvar and 3 vaginal melanomas. The patients were mostly postmenopausal women (8/9), had a mean age of 67 years (range, 44-85 years), and had mucosal lentiginous (7) or nodular (2) melanomas. In the adjacent skin/mucosa, mucosal melanosis was found in 5, lichen sclerosus or a lichenoid mucositis in 4, and blue nevi in 2 women. With nested polymerase chain reaction techniques followed by direct sequencing, HPV DNA was identified in 6 of 9 (67%) melanomas; these were either cutaneous (HPV 3) (4/9) or epidermodysplasia verruciformis-associated types (HPV 38, Z95969, AJ00151) (4/9). Epidermodysplasia verruciformis-associated HPV (type 15) was found solely in 1/10 (10%) normal vulvar controls. Genital-mucosal HPV types were not detected either by degenerate nested polymerase chain reaction or type-specific probes for HPV 16. We propose that the above findings are not coincidental but may represent a molecular record of HPV involvement in pathogenesis or progression of melanoma, which is consistent with the strong but poorly defined association of cutaneous HPV types with nonmelanoma skin cancers. The theory that HPV may act as a cofactor in melanoma development deserves further clinical and experimental investigations.

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
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
In a woman with cervical cancer and a distant lesion, the histologic distinction of metastatic cervical cancer versus another primary tumor or metastases from another cancer can be difficult and has important clinical implications. Criteria for inclusion in the study were a history of primary cervical cancer and a new lesion in which the pathologic differential diagnosis was metastatic cervical cancer versus new primary versus metastatic ovarian carcinoma. Ten cases were identified. The cervical cancers and the other lesion(s) were tested for human papillomavirus DNA by in situ hybridization and human papillomavirus RNA (E6/E7) by reverse transcriptase in situ polymerase chain reaction. Human papillomavirus DNA was detected in the primary cervical cancer by in situ hybridization in five of nine cases; viral RNA was detected by reverse transcriptase in situ polymerase chain reaction in nine of nine cases (one case was not available for viral testing). In six cases, human papillomavirus was detected in the subsequent lesion (three lung, one cervical lymph node, two retroperitoneum), documenting the latter was metastatic cervical cancer. Human papillomavirus was not detected in the other four cases (two lung, two retroperitoneum in women with ovarian cancer), documenting that they were either primary lung cancers or metastatic ovarian cancers, respectively. Reverse transcriptase in situ polymerase chain reaction for human papillomavirus RNA is a reliable method to differentiate metastatic cervical carcinoma from either a new primary tumor or a metastasis from another cancer.
