Abstract
PURPOSE This scoping review aimed to identify factors associated with the recurrence of ameloblastoma. METHODS Systematic searches were conducted in PubMed, Scopus, and EMBASE, based on the board research question: "What factors are related to the recurrence of ameloblastoma?". English-language observational studies addressing the risk and preventive factors associated with recurrent ameloblastoma were included and data were extracted. RESULTS Eighty-three retrospective observational studies met the inclusion criteria. The identified prognostic factors for recurrence included: (1) Tumor size/diameter/volume, (2) cortical bone perforation/ soft tissue invasion, (3) multilocular radiolucency, (4) impacted tooth-involving lesions, (5) root resorption, (6) WHO classification - conventional (solid/multicystic) ameloblastoma, (7) histological subtype - mural invasion of unicystic ameloblastoma, (8) conservative treatment modalities - simple enucleation, curettage, and marsupialization, and (9) non-extraction/preservation of involved teeth. No strong evidence linked immunohistochemical expression to recurrence. Interestingly, BRAF p.V600E remained controversial in terms of recurrence, despite being a frequent finding in ameloblastoma. CONCLUSION Certain clinical characteristics, radiographic findings, histological subtypes, and treatment choices of ameloblastoma can help identify patients at high risk of recurrence. Further prospective studies to evaluate the prognostic factor model and research on immunohistochemistry are required.

Abstract
BACKGROUND Ameloblastoma is a benign but aggressive epithelial odontogenic neoplasm of unknown etiology. The role of human papilloma virus (HPV) in the etiology of oral squamous cell carcinoma has prompted the investigation of HPV as an etiologic factor in ameloblastoma. This study aimed to determine the frequency of high-risk (HR) HPV in conventional ameloblastoma and the clinical parameters associated with infection. MATERIALS AND METHODS The study was approved by the ethical review boards of the institution. DNA was extracted from fresh tissue collected 750 μL of DNA/RNA Shield (Zymo Research, United States) using Invitrogen PureLink Viral RNA/DNA Mini Kit (Invitrogen, USA). The extracted DNA was assayed for the detection of 14 HR HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) using Anyplex™ II HPV HR Detection kit (Cat. No. HP7E00X) (Seegene Inc., Republic of Korea) on CFX-96TM Real-Time Polymerase Chain Reaction (PCR) System (Bio-Rad). Data on gender, age of patient, site of lesion, clinicohistological types of ameloblastoma and history of smoking, alcohol consumption, and practice of oral sex were collected. Data analysis was performed using analysis program SPSS version 25 and statistical significance was set at P < 0.05. RESULTS Two cases of conventional ameloblastoma were positive with HPV and none of the ameloblastic carcinoma cases were positive. The HPV 16 serotype was observed in both cases. While 5 of the cases had a history of alcohol consumption, none of these cases were positive for HPV serotype. CONCLUSIONS HPV 16 positivity was detected in two cases of conventional ameloblastomas and none in ameloblastic carcinoma using real-time PCR. There was no effect of exposure to smoking, alcohol consumption, and practice of oral sex and HPV in the etiology of ameloblastoma. Data available are suggestive of a limited role of HPV in the etiology of ameloblastoma.

Abstract
Introduction head and neck cancers have essentially been a disease of the elderly but recent studies are beginning to demonstrate their increasing incidence in young people with infections such as human papilloma virus (HPV). This study was carried out to determine the prevalence of high risk Human papilloma virus (hrHPV) related oropharyngeal carcinoma and its prevalent genotypes as well as their strength of association with HIV in adult Nigerian subjects. Methods this was a cross-sectional study of 41 patients with oropharyngeal carcinomas seen over a 2-year period. Patients had incisional and/or excisional biopsy done under anesthesia. A portion of the specimen from which the DNA was extracted was placed in Digene HC2 DNA collection device while the 2nd portion for histopathological analysis was fixed using 10% Neutral Buffered Formalin (NBF) and embedded in paraffin blocks. Oropharyngeal cancer HPV genotyping was done using HPV genotypes 14 real-tm quant kit (SACACE, Italy). The data was analyzed using SPSS version 23. Results prevalence of HPV was 17.1% with a male to female ratio of 2.7: 1. The identified genotypes were 16, 33, 35 and 52 with 28.6% of patients having more than one genotype. Most of the age groups studied were affected. Squamous cell carcinoma and ameloblastic carcinoma were the cancers associated with HPV. HPV was not identified in the HIV positive patients. Conclusion high-risk human papilloma virus genotypes 16, 33, 35 and 52 are associated with oropharyngeal carcinoma in Nigeria but were not found in HIV patients. This finding provides a strong evidence for the use of the 9-valent prophylactic vaccine for the prevention of oropharyngeal cancer in Nigeria. Public awareness and HPV prevention strategies should reduce significantly the incidence of oropharyngeal carcinomas in our environment.

Abstract
Objective: To study the clinocopathological factors and presence of Human Pappiloma Virus in ameloblastoma by immnohistochemistry. Methods: It was a cross sectional study on 50 surgical specimens of ameloblastoma, completed in six months. These were selected and processed for initial screening by H&E and then by immunohistochemistry (IHC) for detection of Human Papilloma Virus (HPV). The questionnaire was designed to study the clinicopathological factors associated in these patients. Sections of 4µm were cut, placed on special positive charged glass slides in the Department of Pathology, King Edward Medical University. It was then examined by the histopathologists for grading and scoring of these lesions. Chi Square test was used to assess the differences found in types of ameloblastomas. The p-value was smaller than 0.05 (p < 0.05). Results: The mean age of the patients (12-80 years old) was 38.6±15.1 years, with male-female ratio 2.84: 1. HPV was positive in 9 (18%), whereas negative in of 41 (82%) patients. Among the positive, reactive HPV with score-1 was 8 and score-2 was 1. According to histological variant, follicular was present in 78%, Plexiform pattern in 8%, Conventional and Desmoplastic variants in one patient each; and Cystic and Acanthomatous were seen in two and three patients respectively. The mandible was involved in 39 patients, maxilla and right maxilla involved in 4 patients each, right retromolar, cheek and angle of mandible was seen in one patient each. About 16% patients had anterior, 66% had posterior and 18% had both anterior and posterior regions involved. Among the HPV positive reactive statistically, no significant difference was found with smoking, Paan and exposure to pesticides, factory or mine (p-value > 0.05). Among HPV positive reactive patients, eight had ameloblastoma whereas, 1 had ameloblastomic fibroma. There was no statistical significance of type, location and region of tumor in HPV positivity. Conclusion: Mandible and posterior region was more commonly involved. Follicular pattern was most common. There was no effect of exposure to pesticides, factory or mine, smoke and human papilloma virus in the etiology of ameloblastoma because only 18% of patients showed the association of HPV16

Abstract
BACKGROUND Ameloblastoma (AM) and odontogenic Keratocyst (OKC) are destructive odontogenic lesions of the gnathion. Although their exact pathogeneses are not yet totally understood, the viral etiopathogenesis in AM and KCOT has been proposed. True to syndromic keratocystic odontogenic tumor (sKCOT) and non-syndromic OKC is the high recurrence rate. OBJECTIVES Given that shared pathways trailed by AM and by sKCOT/OKC have been suggested, this study, however, contrasts the expression of AM and OKC for viral antibodies. METHOD A total of archival 80 paraffin blocks of cases of parakeratinized odontogenic keratocyst (non-syndromic KCOTs) and of ameloblastomas (n = 40 for each) were included in this study to be sectioned and stained for two immunohistochemical markers: anti-human papillomavirus and Epstein-Barr virus-encoded latent membrane protein. RESULTS All the submitted cases of AM and parakeratinized OKC were negative for both markers: anti-HPV and anti-LMP-1. CONCLUSIONS Although results could have been biased, given the same ethnic group and territory examined in this study, all cases were negative for both markers. Therefore, the viral contribution to the etiopathogenesis in AM and OKC could not be established in this study.

Abstract
OBJECTIVE The role of human papillomavirus (HPV) in keratinizing odontogenic cysts (OC) has only rarely been studied. We describe the clinicopathologic findings in a series of OCs that had unusual keratinization patterns and were investigated for a possible HPV etiology. STUDY DESIGN Tissue samples from 29 patients with keratinizing OCs were studied for light microscopic features suggestive of HPV infection and by an HPV DNA polymerase chain reaction assay. RESULTS The mean age at presentation was 31.1 years; 79.3% of the OCs occurred in the mandible and 46.4% were associated with an impacted tooth. The phenotypic characteristics koilocytes, hypergranulosis, and a verrucous pattern of the cyst-lining epithelium were observed in 69%, 62.1%, and 17.2% of cases, respectively. These histomorphologic features did not, however, correlate with HPV infection. CONCLUSIONS HPV does not appear to play a role in keratinizing OCs and is not responsible for the wart-like histomorphologic features that may be seen in these lesions.

Abstract
Human papillomavirus (HPV) has been associated with a variety of head and neck neoplasms, including squamous cell carcinomas and Schneiderian papillomas. Ameloblastomas can arise from either the gnathic bones or peripheral soft tissues. Peripheral sinonasal ameloblastomas share clinical features with Schneiderian papillomas. A small number of reports have described detection of HPV DNA within ameloblastomas. However, Most of these cases was reported in the 1990s, used the polymerase chain reaction technique, and only examined gnathic tumors. The current study was designed to determine whether low- or high-risk HPV DNA could be detected in gnathic or peripheral ameloblastomas using in situ hybridization. Twenty-nine examples of gnathic osseous and peripheral head and neck ameloblastomas were obtained from the authors' archives (University of Virginia and the Johns Hopkins Hospital). High-risk HPV DNA was not detected in any of the 29 tumors analyzed. Low-risk HPV DNA was identified in only 1 tumor, which was peripheral in origin, and from an immunocompromised patient. We believe that the HPV in this case represents a background "passenger" infection. This study demonstrates that HPV of either high- or low-risk subtypes is unlikely to play a role in the pathogenesis of sinonasal ameloblastomas.

A retrospective investigation on canine papillomavirus 1 (CPV1) in oral oncogenesis reveals dogs are not a suitable animal model for high-risk HPV-induced oral cancer. PLoS One 2014; 9:e112833.

Abstract
CPV1 (also called COPV) is a papillomavirus responsible for oral papillomatosis in young dogs. The involvement of this viral type in oral oncogenesis has been hypothesized in oral squamous cell carcinomas (SCCs), but has never been investigated in other neoplastic and hyperplastic oral lesions of dogs. Aim of this study was to investigate the presence of CPV1 in different neoplastic and hyperplastic lesions in order to assess its role in canine oral oncogenesis; according to the results obtained, a second aim of the study was to define if the dog can be considered a valid animal model for oral high risk HPV-induced tumors. Eighty-eight formalin-fixed, paraffin-embedded (FFPE) canine oral lesions including 78 oral tumors (papillomas, SCCs, melanomas, ameloblastomas, oral adenocarcinomas) and 10 hyperplastic lesions (gingival hyperplasia) were investigated with immunohistochemistry for the presence of papillomavirus L1 protein and with Real-Time PCR for CPV1 DNA. RT-PCR for RNA was performed on selected samples. All viral papillomas tested were positive for immunohistochemistry and Real-time PCR. In 3/33 (10%) SCCs, viral DNA was demonstrated but no viral RNA could be found. No positivity was observed both with immunohistochemistry and Real-Time PCR in the other hyperplastic and neoplastic lesions of the oral cavity of dogs. Even though the finding of CPV1 DNA in few SCCs in face of a negative immunohistochemistry could support the hypothesis of an abortive infection in the development of these lesions, the absence of viral RNA points out that CPV1 more likely represents an innocent bystander in SCC oncogenesis. The study demonstrates a strong association between CPV1 and oral viral papillomas whereas viral contribution to the pathogenesis of other oral lesions seems unlikely. Moreover, it suggests that a canine model of CPV1 infection for HPV-induced oncogenesis could be inappropriate.

Abstract
Verrucous odontogenic cysts (OCs) are extremely rare. Here, we report the clinicopathologic features of this unusual entity and investigate the role of human papillomavirus (HPV) by p16INK4A immunohistochemistry and HPV-DNA polymerase chain reaction (PCR). A 32-year-old male presented with a 8.3 × 4.0 cm, multilocular radiolucency of the left ascending ramus of the mandible. Microscopically, the cystic cavity was lined by hyperplastic stratified squamous epithelium demonstrating marked verrucous morphology with multiple sharp or blunt projections. Mild dysplastic features were also identified. A final diagnosis of keratinizing OC with verrucous hyperplasia and epithelial dysplasia was rendered. Immunohistochemically, the verrucous OC showed foci of moderate-to-intense and diffuse, nuclear, and cytoplasmic p16INK4A positivity as well as weak or absent p53 immunopositivity in the p16INK4A labeled areas. The Ki-67 expression was increased. Interestingly, HPV-DNA PCR failed to reveal transcriptionally active HPV genotypes. Complete surgical excision was performed, with no recurrences seen during a 66-month follow-up.

Abstract
The aim of the current study was to investigate the presence of human papillomavirus (HPV) and evaluate its association with Ki-67 and cyclooxygenase-2 (COX-2) expressions in keratocystic odontogenic tumor (KCOT). Nineteen cases were included in the present study. Conventional PCR method and immunohistochemical analysis were performed for the detection of HPV-DNA and HPV-L1 capsid protein. Moreover, the expressions of Ki-67 and COX-2 proteins were analyzed immunohistochemically. HPV-DNA was detected in 36.8% (7/19) of tumor samples, whilst HPV-L1 protein was identified in 68.4% (13/19) of them. The Kappa coefficient statistical test showed a moderate agreement (κ 0.424) between PCR and IHC assays for HPV detection. Expression of HPV-DNA was positively correlated with Ki-67 and COX-2 expressions (p < 0.05), whereas HPV-L1 positive staining was positively correlated with COX-2 (p < 0.05) and highly associated with those of Ki-67 (p < 0.01). There was no significant correlation between the presence of HPV and the recurrence of the studied lesions. The results of the current study showed that active HPV infection was present in the odontogenic epithelium of KCOT, and it was associated with increased proliferation rate and COX-2 expression. These findings suggest that HPV may have a role in the pathogenesis and aggressiveness of KCOT. Based on these conclusions, we recommend further investigations of HPV vaccine or antiviral therapy and COX-2 inhibitors as nonsurgical options in the prevention and management of KCOT.
