Abstract
A 35-year-old male presented with recurrent respiratory papillomatosis. Human papillomavirus type 11 was detected from all sites of tumor tissue DNA by PCR. The pre-surgery cell-free DNA (cfDNA) viral load (3.33 × 103 copies/ng DNA) fell below the post-surgical detection limits on achieving remission, suggesting cfDNA's potential as a biomarker.

Abstract
Human papillomavirus (HPV) infection has emerged as an etiologic factor of squamous papilloma (SP). The oropharynx and larynx are common sites of SP, but studies on the prevalence of HPV infection in these sites are lacking. This study aimed to evaluate and compare the prevalence and characteristics of HPV infection in oropharyngeal SP (OPSP) and laryngeal SP (LSP). HPV detection and genotyping data of patients with pathologically confirmed OPSP and LSP were retrospectively analyzed. A total of 119 patients were enrolled, consisting of 93 patients with OPSP and 26 patients with LSP. Of those patients, 13 patients with OPSP and 14 patients with LSP were positive for HPV infection, accounting for a prevalence of 14.0% and 53.8%, respectively (p < 0.001). The most prevalent genotype was HPV16 in OPSP and HPV6 in LSP. Over two-thirds (69.2%) of HPV(+)-OPSP infections were high-risk types compared with 14.3% of HPV(+)-LSP infections (p = 0.004). The prevalence of HPV infection in patients with OPSP and LSP demonstrated no differences in terms of age, sex, and smoking status. These results could provide a better understanding of HPV infection in OPSP and LSP and serve as a background for the epidemiology of HPV-related tumorigenesis of the oropharynx and larynx.

Abstract
Squamous papillomas (SPs) of the head and neck are usually benign lesions associated with human papilloma virus (HPV) infection. However, the reported HPV detection rates vary widely, especially with respect to anatomical distribution. The etiology of SPs in the head and neck remains unclear; analyzing HPV genotypes of SPs based on anatomical sites could assist in clarifying the pathogenesis of SPs in the head and neck. Therefore, the aim of this study was to review the prevalence, subtypes, and anatomical distribution of HPV in head and neck SPs at a hospital in China; we also investigated whether p16, a marker of HPV infection in oropharyngeal carcinoma, could serve as a surrogate marker for HPV in head and neck SPs. The presence of HPV DNA of 23 types (5 low-risk HPV and 18 high-risk HPV types) was detected via real-time PCR. p16 immunohistochemistry was performed using SP sections. Age, sex, anatomical location, and HPV subtype were recorded for each case. In total, 105 SPs were identified, including 47 in the larynx, 42 in the pharynx, 6 in the external auditory canal (EAC), 5 in the oral cavity, and 5 in the nasal cavity. HPV was found in 57 (54.3%) cases, with the highest positivity rate in the larynx (46/47; 97.9%). Only 5/42 (11.9%) patients showed HPV positivity in the pharynx. HPV incidence was highly dependent on the anatomical site. SPs in the larynx and EAC were more likely to carry HPV than those in other anatomical sites. High-risk HPV infections were rarely associated with SPs in the head and neck region. The sensitivity and specificity of p16 immunohistochemistry for HPV infection were 88% and 96%, respectively. There may be an association between p16 and HPV infection in head and neck SPs, but further studies are needed to validate this assertion.

Abstract
Recurrent respiratory papillomatosis (RRP) has a wide range of severity. We investigate the relationship between human papillomavirus (HPV) particle production and severity of RRP. From September 2005 to June 2021, 68 RRP samples (from 29 patients) were included. HPV type was determined. HPV viral load, physical status, and demographic and clinical characteristics were assessed. Immunohistochemistry (IHC) was performed for p16, Ki-67, L1, and E4. We used NanoSuit-CLEM (correlative light and electron microscopy) and transmission electron microscopy (TEM) to examine the samples. The total number of surgeries in HPV-positive and HPV-negative cases were 3.78 (n = 55/68, range: 1-16) and 1.30 (n = 13/68, range: 1-3), respectively (p = 0.02). IHC showed that L1 and E4 were correlated and expressed on the tumour surface. NanoSuit-CLEM and TEM revealed HPV particles in L1-positive nuclei. L1 IHC-positive cases had a shorter surgical interval (p < 0.01) and more frequent surgeries (p = 0.04). P16 IHC, viral load, and physical status were not associated with disease severity. This study visualised HPV particle production in RRP for the first time. Persistent HPV particle infection was associated with severity. We suggest L1 IHC for evaluating RRP severity in addition to the Derkay score.

Abstract
INTRODUCTION Herein we describe a series of rare peripheral pulmonary neoplasms temporarily termed "peripheral type squamous cell neoplasm of uncertain malignant potential (PSCN-UMP)" and investigate their relationship to bronchiolar adenoma (BA) and squamous cell carcinoma (SCC). MATERIALS AND METHODS The histologic and immunohistochemical features of 10 PSCN-UMPs and six BAs were compared. Whole exome sequencing (WES) and bioinformatics analysis were performed to further compare the genetic features of PSCN-UMPs, BAs, and NSCLCs. RESULTS All PSCN-UMPs were peripherally located and histologically characterised by the lepidic, nested, and papillary proliferation of relatively bland squamous cells, accompanied by entrapped hyperplastic reactive pneumocytes. The basal squamous cells coexpressed TTF1 and squamous markers. Both cellular components exhibited bland morphology and a low proliferative activity. The six BAs met the morphologic and immunophenotypic features of proximal-type BA. Genetically, driver mutations, including frequent EGFR exon 20 insertions, were found in PSCN-UMPs, while the KRAS mutation, BRAF mutation, and ERC1::RET fusion were detected in BAs. PSCN-UMPs also shared some alterations with BAs in mutational signatures, while copy number variants (CNV) were enriched in MET and NKX2-1 in PSCN-UMP and MCL1, MECOM, SGK1, and PRKAR1A in BA. CONCLUSION PSCN-UMPs exhibited the proliferation of bland squamous cells accompanied by entrapped pneumocytes and frequent EGFR exon 20 insertions, which showed distinct features from BAs and SCCs. Recognition of this specific entity will help to expand the morphologic and molecular spectrum of peripheral lung squamous neoplasms.

Abstract
Studies on human papillomavirus (HPV) infection in oropharyngeal squamous papilloma (OPSP) are lacking, although HPV infection has been recognized as the primary cause of oropharyngeal cancer for several decades. This study aimed to evaluate the prevalence and characteristics of HPV infections in patients with OPSP. We retrospectively enrolled patients with histologically confirmed OPSP in whom the presence of HPV infections and p16 expression were evaluated. The results of HPV infection in OPSP were analyzed according to the clinicodemographic profiles. Of the 83 patients included in this study, HPV test results were positive in 12 patients, with an overall prevalence of 14.5%. HPV genotypes involved low-risk and high-risk HPV types in three (3.6%) and nine (10.8%) patients, respectively. The most prevalent genotype was HPV16, accounting for 58.3% of all HPV infections. None of the OPSPs showed p16 IHC positivity. There were trends toward a higher prevalence of high-risk HPV infection in patients with OPSP aged ≤45 years, never-smokers, and those with multifocal diseases. These findings could enhance our understanding of HPV infection in OPSP and be used as valuable epidemiological data for the management of HPV-associated OPSP and regarding the possible efficacy of HPV vaccinations in OPSP.

Abstract
Highlights Abstract Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is better than white-light endoscopy in detecting LSCC and LP. They also reported that LP is frequently mistaken for LSCC, resulting in high rates of false positives using NBI. This is the first review that emphasized this NBI limitation in distinguishing between LP and LSCC in cases of a type V pattern of intraepithelial papillary capillary loop. Although NBI application increased the rate of early cancer detection, LP reduces NBI accuracy. This drawback may lead to misdiagnosis and improper treatment. Our advice is to be careful in cases of type V pattern on NBI and to research LP epithelial and clinical features because it could be a pitfall.

Abstract
Sinonasal inverted papilloma (SNIP) can recur; however, the factors related to tumor recurrence remain unclear. This study aimed to analyze risk factors, including human papillomavirus (HPV) infection, as well as other factors associated with SNIP recurrence. Thirty-two patients who were diagnosed with SNIP and underwent surgery between 2010 and 2019 were enrolled: 24 men and 8 women, with a mean age of 59.2 years. The mean follow-up was 57.3 months. Demographics and information about history of smoking, diabetes mellitus (DM), hypertension, allergic rhinitis, alcohol consumption, tumor stage, surgical approach, and recurrence were reviewed retrospectively. Specimens were investigated using polymerase chain reaction to detect HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11). Seven patients (21.9%) experienced recurrence. HPV DNA was detected in five (15.6%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 3). Patients with recurrence of SNIP had a higher proportion of young adults and displayed higher rates of HPV infection, DM, and advanced tumor stage than those without recurrence. HPV infection, young adulthood, DM, and advanced tumor stage could be associated with a high recurrence rate, which suggests that patients with these risk factors could require close follow-up after surgery.

Abstract
Objective: The aim of our retrospective study is to compare the long-term recurrence rate of the benign oral squamous papilloma (OSP) with different laser-assisted treatments and conventional procedures (use of scalpels) aiming to suggest the most suitable surgical protocol showing the lowest recurrence rate. Background: A retrospective multicenter DATA collection between 1985 and 2019 covering 781 OSP cases concerning different surgical protocols used for the treatment of OSP was done and included the use of different laser wavelengths [neodymium-doped yttrium-aluminum-garnet (Nd:YAG), carbon dioxide (CO2), and Diode 980 nm] and the conventional surgeries using the scalpel. The age, sex, and the oral location of the OSP were noted. Methods: Three different surgical protocols were selected in our study: protocol 1 regrouped surgical procedures performing the excision of OSP with an in-depth safety margin of 1 mm and just at the base of the tumor with reduced excision of the grossly normal marginal mucosa around the tumor (0-1 mm). Protocol 2 and 3 were similar to protocol 1, but with an additional excision of 1-2 mm and ≥3 mm of the grossly normal marginal mucosa, respectively, for group 2 and 3. All laser-treated OSP wounds were left without sutures. In the conventionally treated OSP, sutures were regularly performed. Follow-up was done after 15 days and at 1, 6, and 18 months. The three included wavelengths were Nd:YAG (1064 nm), CO2 laser (10,600 nm), and diode laser (980 nm). Results: After 18 months of follow-up, the highest success rate was obtained with protocol 3 (100% with Nd:YAG, 99% with CO2, 98.4% with diode, and 99% with the scalpel), which was significantly higher than the values of protocol 2 (96.6% with Nd:YAG, 91% with CO2, 96% with diode, and 95% with the scalpel) and the protocol 1 (38% with Nd:YAG, 29% with CO2, 33% with diode, and 30% with the scalpel). The oral locations of OSP were 30% on palates, 30% on the tongue, 16% on cheek, 14% on lips, and 10% on other locations. Conclusions: The lowest recurrence rate was observed when a minimum of three millimeters (≥3 mm) of grossly normal aspect mucosa around the OSP was included in the excisions. The laser wavelengths and the use of scalpel did not show any significant difference in terms of recurrence.

Abstract
Squamous papilloma is a benign mass lesion of the oral mucosa. For papillomas of the tongue, surgery is recommended owing to their malignant potential; however, certain complications may be associated with surgery. A traditional Japanese (Kampo) herbal medicine, Keishibukuryogan-ka-yokuinin (KBGY), has been used to treat viral warts and various skin diseases in Japan. Therefore, the effect of KBGY on papillomas is promising. A 49-year-old Japanese man presented with a wart on his tongue that was about 3 months old. He smoked 5 cigarettes per day. He did not drink alcohol. He had no history of malignant illnesses. He was taking alprazolam for panic disorder. The patient was diagnosed with a suspected papilloma of the tongue at the Department of Otolaryngology and was advised to undergo an excision biopsy to exclude malignancy. However, he refused owing to the fear of an invasive procedure. After informed consent was obtained from the patient, KBGY was prescribed. Three months later, the wart on his tongue spontaneously prolapsed. The histopathological diagnosis was squamous papilloma. There was no indication of malignancy, and the patient discontinued Kampo treatment. He has had no recurrence in the past 3 years. KBGY is a combination of Keishibukuryogan and yokuinin (adlay seeds). Keishibukuryogan may be beneficial for skin or oral mucosal remodeling, and yokuinin may have antiviral properties. The present case report suggests the use of KBGY as an appropriate complementary therapy for squamous papilloma.

Abstract
Introduction: P16 overexpression is considered as a good prognostic marker for oropharyngeal squamous cell carcinoma. However, there are very few literatures on the prevalence and outcomes of p16 overexpression in non-oropharyngeal squamous cell carcinoma and benign head and neck tumors. The aim of our study was to estimate the hospital based prevalence of p16 positive laryngeal and pharyngeal tumors and to compare it with the prevalence of p16 expression in the non tumor tissue (tonsils). Methods: This was a descriptive cross-sectional study. Cases of all genders >15 years presenting with malignant or benign tumors of larynx and all the subsites of pharynx were included in the study for evaluation of p16 expression by immunohistochemistry. Tonsillar tissue of cases undergoing tonsillectomy for recurrent acute tonsillitis were taken as non-tumorous tissue to evaluate for p16 expression. Results: A total of 48 cases were included in our study with 24 cases having different tumors of head and neck region and 24 cases having recurrent acute tonsillitis who were kept under non-tumor group. Eight cases (33.3%) in the tumor group showed positive stain for p16 in IHC. In non tumor group, 7 cases (29.1%) showed positive IHC staining for p16. Conclusions: P16 expression can be present in both benign and malignant tumors of various subsites of head and neck region and also in tonsillar tissue affected by inflammation.

Abstract
Squamous cell papilloma (SCP) is generally a human papillomavirus (HPV) induced exophytic or endophytic proliferation on the surface of the skin, oral cavity, larynx, esophagus, cervix, vagina, and anal canal. The endophytic type SCP can cause differential diagnostic difficulties with keratoacanthoma, inverted follicular keratosis, and squamous cell carcinoma; however, these lesions are not associated with HPV infection. The authors present a female patient who noticed an extremely rapidly growing tumor destructing the left lower eyelid. The histological analysis of the biopsy sample revealed a virus-induced squamoproliferative lesion. The eyelid affected was completely removed, and the histological examination resulted in a HPV induced endophytic squamous cell papilloma. The tarsus and the conjunctiva were replaced by a chondromucosal graft harvested from the nasal septum, while the skin defect could be closed directly. Restoration of the eyelid function has been achieved with satisfying functional and cosmetic results.

The Prevalence, Anatomic Distribution and Significance of HPV Genotypes in Head and Neck Squamous Papillomas as Detected by Real-Time PCR and Sanger Sequencing. Head Neck Pathol 2019; 14:428-434. [PMID: 31352627 PMCID: PMC7235102 DOI: 10.1007/s12105-019-01057-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2019] [Accepted: 07/19/2019] [Indexed: 11/25/2022]
Abstract
Squamous papillomas (SPs) of the head and neck are generally regarded as a human papillomavirus (HPV)-driven process, but reported rates of HPV detection vary dramatically. Moreover, they are generally considered a benign condition, but the detection of high risk HPV types is commonly reported. This latter finding is particularly disturbing to clinicians and their patients given the alarming rise of HPV-associated head and neck cancer. The capriciousness of HPV detection reflects in large part differences in methodologies. The purpose of this study was to review an institutional experience using a state of the art detection method to determine the presence, type and anatomic distribution of HPV in head and neck SPs. The surgical pathology files of the Mount Sinai Hospital were reviewed for all SPs that had undergone HPV testing between 2012 and 2018. HPV screening was performed on tissue blocks with real-time PCR using primers designed to target the L1 region of low and high-risk HPV types. Genotyping was performed on HPV positive cases. HPV detection was repeated for cases that were originally reported to be positive for high risk HPV. 134 cases had undergone HPV analysis. Of the 131 with sufficient cellular material, 2 were excluded because the HPV testing yielded inconclusive results. The remaining 129 cases were the basis of this study. Thirty-eight cases (29%) were HPV positive and 91 (71%) were negative. The most common genotype was HPV 6 (n = 27, 71%), followed by HPV 11 (n = 10, 26%). One case (1%) was HPV positive but the genotype could not be determined. Of the HPV negative cases, 3 were originally reported as HPV 16 positive but found to be HPV negative on re-review and repeat testing. SPs arising in the larynx were more likely to harbor HPV than those arising in the oral cavity and oropharynx (64% vs. 10%, p < 0.00001). Similarly, recurrent respiratory papillomatosis (RRP) were much more likely to be HPV positive than solitary SPs (71% vs. 10%, p < 0.00001). Almost a third of head and neck SPs harbor HPV, but incidence is highly dependent on anatomic site. Those arising in the larynx are more prone to be HPV-driven than those arising in the oral cavity and oropharynx, particularly when occurring in the setting of RRP. High risk HPV could not be confirmed in any of the cases. Routine HPV testing as a strategy to unmask potentially malignant lesions harboring high risk HPV is not likely to be useful.

Abstract
Background: p16INK4a (p16) expression in tongue cancer (TC) is reportedly not associated with human papilloma virus (HPV). Mutations of KRAS in cancer cells are most frequently observed within codon 12. However, few reports have investigated the association between KRAS mutations and p16 status in TC. Objectives: This study aimed to evaluate the influence of KRAS mutations on TC. Methods: Clinical records and surgically resected specimens of 85 TC patients were analyzed. Tumor samples were analyzed for mutations of KRAS located within codons 12 and 13. p16 staining was performed and considered positive in cases with moderate to strong nuclear and cytoplasmic staining. Results: Positive p16 staining was observed in 10 cases (11.8%). A KRAS mutation was detected in one case (1.2%). The case with KRAS mutation showed negative p16 staining. Despite being at an early stage, the patient died of lung metastasis at 43 months from initial treatment. Conclusions and Significance: KRAS mutations are not associated with p16 expression in TC and may predict poor prognosis in TC patients. Further analysis of mutations in regions other than codons 12 and 13 of KRAS will be necessary to determine the relationship between KRAS mutations and prognosis of this disease.

Abstract
BACKGROUND Long-term smoking and drinking are known to contribute to the onset of tongue cancer (TC). However, the increasing incidence of TC in younger adults has been suggested to be associated with other factors. OBJECTIVES The present study investigated the relationship between TC and human papillomavirus (HPV) infection. MATERIAL AND METHODS Clinical records and surgically resected specimens from 86 patients (<40-years-old, n = 12; ≥40-years-old, n = 74) with TC were analyzed. Strong nuclear and cytoplasmic p16 staining was considered positive. HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11) was detected using consensus primer-mediated polymerase chain reaction. RESULTS Strong p16 expression was observed in 10 (11.6%) patients. HPV DNA was detected in 9 (10.5%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 7). Strong p16 expression was observed more frequently among younger adults than among older adults (33.3% vs. 8.1%; p = .045). p16 staining did not correlate with the detection of HPV DNA (correlation coefficient, 0.113; p = .300). CONCLUSIONS AND SIGNIFICANCE In TC, p16 expression was not associated with HPV infection, suggesting that it may be caused by a different mechanism.
