Abstract
Infectious susceptibility is a component of many inborn errors of immunity. Nevertheless, antibiotic use is often used as a surrogate in history taking for infectious susceptibility, thereby disadvantaging patients who present with viral infections as their phenotype. Further complicating clinical evaluations are unusual manifestations of viral infections which may be less familiar that the typical respiratory viral infections. This review covers several unusual viral phenotypes arising in patients with inborn errors of immunity and other settings of immune compromise. In some cases, chronic infections lead to oncogenesis or tumor-like growths and the conditions and mechanisms of viral-induced oncogenesis will be described. This review covers enterovirus, rubella, measles, papillomavirus, and parvovirus B19. It does not cover EBV and hemophagocytic lymphohistiocytosis nor lymphomagenesis related to EBV. EBV susceptibility has been recently reviewed. Our goal is to increase awareness of the unusual manifestations of viral infections in patients with IEI and to describe treatment modalities utilized in this setting. Coincidentally, each of the discussed viral infections can have a cutaneous component and figures will serve as a reminder of the physical features of these viruses. Given the high morbidity and mortality, early recognition can only improve outcomes.

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
Merkel cell polyomavirus (MCPyV or MCV) is a novel human polyomavirus that has been discovered in Merkel cell carcinoma (MCC), a highly aggressive skin cancer. MCPyV infection is widespread in the general population. MCPyV-associated MCC is one of the most aggressive skin cancers, killing more patients than other well-known cancers such as cutaneous T-cell lymphoma and chronic myelogenous leukemia (CML). Currently, however, there is no effective drug for curing this cancer. The incidence of MCC has tripled over the past two decades. With the widespread infection of MCPyV and the increase in MCC diagnoses, it is critical to better understand the biology of MCPyV and its oncogenic potential. In this chapter, we summarize recent discoveries regarding MCPyV molecular virology, host cellular tropism, mechanisms of MCPyV oncoprotein-mediated oncogenesis, and current therapeutic strategies for MCPyV-associated MCC. We also present epidemiological evidence for MCPyV infection in HIV patients and links between MCPyV and non-MCC human cancers.

Abstract
BACKGROUND Epidermodysplasia verruciformis (EV) is a genodermatosis leading to infections with cutaneous HPV, persistent plane warts and a high rate of non-melanoma skin cancer (NMSC). Biallelic loss-of-function mutations in TMC6 and TMC8 are known to be causative. OBJECTIVE The aim of this study was to report EV-causing mutations in four patients with EV and to give an overview of all described patients with EV. PATIENTS AND METHODS We investigated four patients with classical features of EV from two families. All patients were affected by plane warts with typical EV histology since early childhood, and β-HPVs were detected on their skin. One patient had recurring cutaneous squamous cell carcinomas (cSCC) and carcinomas in situ (Bowen type). We sequenced both TMC6/8 for disease-causing mutations and quantified levels of gene expression. We also performed a systematic literature review to discuss these patients in the context of previously reported cases, mutations already identified, as well as HPV types. RESULTS Three patients of one family carried a homozygous splice site mutation in TMC8 resulting in aberrantly spliced transcripts that were not degraded. By contrast, no TMC6/8 mutation was detected in the patient from the other family. A systematic literature review revealed 501 described patients with EV. Around 40% of patients with EV analysed for genetic alterations carried no mutation in TMC6/8. While β-HPVs were identified in the majority of cases, α-HPVs were detected in several individuals. CONCLUSION The relatively high proportion of EV patients without mutation in TMC6/8 indicates the existence of EV-causing mutations in additional, presently unknown gene(s). However, a homozygous TMC8 splice site mutation in our patients resulted in aberrant transcripts which cannot retain the healthy phenotype. The literature review revealed that HPV-5 is the most commonly identified HPV in patients with EV, but HPV-3, HPV-14 and HPV-20 were unexpectedly identified more frequently than HPV-8.

Re-evaluation of epidermodysplasia verruciformis: Reconciling more than 90 years of debate. J Am Acad Dermatol 2017; 76:1161-1175.

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 Studies of Merkel cell polyomavirus (MCPyV) in nonmelanoma skin cancers (NMSC) other than Merkel cell carcinoma (MCC) produced controversial results. Therefore, we studied the prevalence of MCPyV in basal cell carcinoma (BCC) and in squamous cell carcinoma (SCC). METHODS Tissue specimens were analyzed for the presence of MCPyV DNA by conventional polymerase chain reaction (PCR). Expression of MCPyV large T protein was determined by immunohistochemistry. RESULTS MCPyV DNA was frequently detected in skin cancers by PCR, in 36 of 88 BCCs, in 21 of 75 SCCs and in 10 of 47 normal skin samples. In BCC, a significant difference in the detection rate compared to normal skin was observed. In contrast, weak reactivity for MCPyV large T antigen was detected only sporadically in immunosuppressed patients (2 of 88 BCCs, 1 of 75 SCCs). Mutations of the large T antigen of MCPyV were more frequently observed in MCC than in BCC/SCC. CONCLUSIONS Our results suggest that the frequent detection of the MCPyV genome in NMSC by PCR reflects ubiquitous spread of the virus. However, the low immunohistochemical detection rate of MCPyV and the lack of MCC-specific MCPyV mutations argue against an essential role of MCPyV in the development of skin cancers other than MCC.

Abstract
Merkel cell polyomavirus (MCPyV) is associated to Merkel cell carcinoma (MCC). We studied 113 MCC tumoral skin lesions originating from 97 patients. MCPyV detection was higher in fresh-frozen (FF) biopsies (94%) than in formalin-fixed paraffin-embedded biopsies (39-47%). Mean viral load in FF tumor was of 7.5 copies per cell with a very wide range (0.01-95.4). Nineteen complete sequences of LTAg were obtained, mainly from FF biopsies when the viral load was high. Seventeen showed stop codons, all localized downstream of the pRb protein binding domain. Sequence comparison and phylogenetic analysis showed that all sequences clustered in the large C clade of MCPyV strains. MCPyV integration was demonstrated in 19 out of 27 FF MCC DNA biopsies without evidence of specific host cellular genome integration site. In 13/19 cases, the viral junction was located within the second exon of the LTAg, after the pRB binding domain.

Abstract
Most Merkel cell carcinomas display pure neuroendocrine differentiation (pure Merkel cell carcinoma), whereas a minority show combined neuroendocrine and nonneuroendocrine elements (combined Merkel cell carcinoma). Recent identification of Merkel cell polyomavirus DNA and Merkel cell polyomavirus large T antigen expression in a proportion of Merkel cell carcinomas has suggested viral-induced oncogenesis. To date, Merkel cell polyomavirus immunohistochemistry has shown an absence of viral large T antigen expression in combined Merkel cell carcinoma as well as select non-Merkel cell carcinoma cutaneous lesions and visceral neuroendocrine tumors. In our series, we aimed to further characterize the frequency and pattern of Merkel cell polyomavirus large T antigen expression by CM2B4 immunohistochemistry in primary and metastatic Merkel cell carcinoma (pure Merkel cell carcinoma and combined Merkel cell carcinoma) and various non-Merkel cell carcinoma lesions from patients with Merkel cell carcinoma, patients without Merkel cell carcinoma, and individuals with altered immune function. Merkel cell polyomavirus large T antigen was detected in 17 (63%) of 27 pure Merkel cell carcinomas and absent in all 15 (0%) combined Merkel cell carcinomas. Furthermore, complete concordance (100%) of Merkel cell polyomavirus large T antigen expression was observed in 10 cases of primary Merkel cell carcinoma and subsequent tumor metastases. We also evaluated 70 non-Merkel cell carcinoma lesions including 15 cases each of pulmonary and gastrointestinal neuroendocrine tumors. All 70 non-Merkel cell carcinoma lesions were negative for Merkel cell polyomavirus by CM2B4 immunohistochemistry, irrespective of any known Merkel cell carcinoma diagnosis and immune status. In summary, our identification of Merkel cell polyomavirus large T antigen expression in a subset of Merkel cell carcinoma and lack of findings in combined Merkel cell carcinomas and non-Merkel cell carcinoma lesions concur with earlier findings and implicate Merkel cell polyomavirus-independent pathogenesis in these cases. Overall, CM2B4 immunohistochemistry appears to be a specific method for Merkel cell polyomavirus detection and has the potential to play an important role in the diagnosis and classification of Merkel cell carcinoma in the future.
