The yearly incidence of syphilis has risen markedly in Japan and worldwide. There has also been an increased incidence of human papilloma virus associated oropharyngeal cancer, which presents with clinical features similar to those of syphilis.

A case of syphilis with clinical manifestation resembling that of human papilloma virus associated oropharyngeal cancer is reported, along with a literature review of similar cases.

Clinical case reports and review of previous literature.

Syphilis may cause irregular mucosal lesions of the oropharynx and cystic lymphadenopathy. It is difficult to diagnose syphilis only by examining pathological specimens, without clinical information such as Treponema pallidum antibody findings. It is necessary to correctly understand the characteristics of syphilis and human papilloma virus associated oropharyngeal cancer to ensure prompt diagnosis and treatment.

Patients with non-Hodgkin's lymphoma and chronic lymphocytic leukaemia are at an elevated risk of further malignancy. Head and neck squamous cell carcinoma often presents with cervical lymph node metastasis, and can pose a diagnostic challenge in patients with non-Hodgkin's lymphoma or chronic lymphocytic leukaemia who may have pre-existing palpable neck nodes.

A retrospective case review of a health board was conducted to identify patients with head and neck squamous cell carcinoma with a previous diagnosis of non-Hodgkin's lymphoma or chronic lymphocytic leukaemia.

Four patients with head and neck squamous cell carcinoma that developed after non-Hodgkin's lymphoma or chronic lymphocytic leukaemia were identified. Two patients had a background of non-Hodgkin's lymphoma treated with chemotherapy. The remaining two patients had a background of chronic lymphocytic leukaemia under active surveillance. Three out of the four patients died within 30 months of diagnosis.

Head and neck squamous cell carcinoma following non-Hodgkin's lymphoma or chronic lymphocytic leukaemia is aggressive. A heightened clinical suspicion is essential to facilitate early diagnosis and treatment of head and neck squamous cell carcinoma in patients with dual pathology.

The National Institute for Health and Care Excellence referral guidelines prompting urgent two-week referrals were updated in 2015. Additional symptoms with a lower threshold of 3 per cent positive predictive values were integrated. This study aimed to examine whether current pan-London urgent referral guidelines for suspected head and neck cancer lead to efficient and accurate referrals by assessing frequency of presenting symptoms and risk factors, and examining their correlation with positive cancer diagnoses.

The risk factors and symptoms of 984 consecutive patients (over a six-month period in 2016) were collected retrospectively from urgent referral letters to University College London Hospital for suspected head and neck cancer.

Only 37 referrals (3.76 per cent) resulted in a head and neck cancer diagnosis. Four of the 23 recommended symptoms demonstrated statistically significant results. Nine of the 23 symptoms had a positive predictive value of over 3 per cent.

The findings indicate that the current referral guidelines are not effective at detecting patients with cancer. Detection rates have decreased from 10–15 per cent to 3.76 per cent. A review of the current head and neck cancer referral guidelines is recommended, along with further data collection for comparison.

To evaluate for the first time the prevalence of human papillomavirus in oropharyngeal squamous cell carcinoma in a Middle-Eastern population, and to determine associations between human papillomavirus profiles and clinicopathological characteristics.

A retrospective chart review was conducted of all patients treated for oropharyngeal squamous cell carcinoma at the Hotel Dieu de France University Hospital (Beirut, Lebanon) between January 2010 and 2016. Existing formalin-fixed paraffin-embedded tumour samples were analysed. Human papillomavirus DNA viral load and p16 expression were evaluated using polymerase chain reaction and immunohistochemistry respectively.

Thirty patients (mean age of 60 years) were included. Twenty-seven per cent of patients were p16-positive/human papillomavirus DNA positive, 53 per cent were p16-negative/human papillomavirus DNA negative and 20 per cent were p16-positive/human papillomavirus DNA negative. Human papillomavirus 16 was the most frequent subtype (75 per cent). Smoking and alcohol consumption were significantly lower in the human papillomavirus positive group compared to the human papillomavirus negative group (p = 0.049 and 0.004, respectively).

Human papillomavirus rate was lower than reported rates in Western populations. Possible explanations include differences in social and cultural behaviours.

The incidence of oropharyngeal squamous cell carcinoma in the Western world is increasing, with the human papillomavirus epidemic implicated in this observed trend. The optimal treatment modality is yet undetermined regarding oncological outcomes.

This study comprised 98 patients with oropharyngeal squamous cell carcinoma, treated with either primary transoral surgery with adjuvant therapy or primary chemoradiotherapy with curative intent, between 2008 and 2012. Clinicopathological characteristics including tumour–node–metastasis stage, human papillomavirus status, treatment modality, recurrence and overall survival were collated.

Five per cent of primary surgical patients had locoregional recurrences compared with 25 per cent of primary chemoradiotherapy patients. A lower rate of locoregional recurrence was observed in the human papillomavirus positive group.

This paper reports higher rates of overall survival and local control for oropharyngeal squamous cell carcinoma treated with primary surgery compared with primary chemoradiotherapy. This reflects overall lower tumour stage and higher human papillomavirus status in this group.

Oropharyngeal cancer is increasing in prevalence in the UK and this is thought to be due to the emergence of disease related to human papilloma virus.

A literature review was conducted on the diagnosis and latest management of oropharyngeal cancer.

In non-smokers, human papilloma virus related disease is thought to have better outcomes, but this casts doubt on previous research which did not stratify patients according to human papilloma virus status. However, this theory provides a route for researchers to risk stratify and de-escalate treatments, and hence reduce treatment burden. In addition, the emergence of minimally invasive transoral techniques allows surgeons to remove large tumours without many of the side effects associated with radical (chemo)radiotherapy.

The emergence of human papilloma virus related disease and minimally invasive techniques have led the clinical and academic community to reconsider how oropharyngeal cancer is managed. Comparative and risk-stratification trials are urgently required and ongoing.

To demonstrate the successful treatment of laryngeal papillomatosis in a 32-month-old girl, using coblation (radio-frequency ablation) resection.

A 32-month-old girl was referred to the ENT out-patients clinic due to a hoarse cry and a very croaky voice since birth. Under general anaesthesia, fibre-optic airway endoscopy revealed a large papillomatous lesion involving the anterior glottis, which was reported as a laryngeal papilloma on histological analysis. This was later excised using an Evac 70Xtra wand. The patient made an uneventful post-operative recovery, and there were no signs of recurrence on repeated airway endoscopies at three and 18 months.

Coblation (radio-frequency ablation) is a promising surgical technique for the treatment of paediatric laryngeal papillomatosis. The main advantages of this technique include limited damage to underlying tissues and a bloodless field.

This study aimed to clarify the local immune status in the larynx in the presence of infection or carcinogenesis associated with human papilloma virus.

Cytological samples (for human papilloma virus detection) and laryngeal secretions (for immunoglobulin assessment) were obtained from 31 patients with laryngeal disease, during microscopic laryngeal surgery. On histological examination, 12 patients had squamous cell carcinoma, four had laryngeal papilloma and 15 had other benign laryngeal disease. Cytological samples were tested for human papilloma virus DNA using the Hybrid Capture 2 assay.

High risk human papilloma virus DNA was detected in 25 per cent of patients (three of 12) with laryngeal cancer. Low risk human papilloma virus DNA was detected only in three laryngeal papilloma patients. The mean laryngeal secretion concentrations of immunoglobulins M, G and A and secretory immunoglobulin A in human papilloma virus DNA positive patients were more than twice those in human papilloma virus DNA negative patients. A statistically significant difference was observed between the secretory immunoglobulin A concentrations in the two groups. Patients with laryngeal cancer had higher laryngeal secretion concentrations of each immunoglobulin type, compared with patients with benign laryngeal disease. The study assessed the mean laryngeal secretion concentrations of each immunoglobulin type in the 12 laryngeal cancer patients, comparing human papilloma virus DNA positive patients (n = 3) and human papilloma virus DNA negative patients (n = 9); the mean concentrations of immunoglobulins M, G and A and secretory immunoglobulin A tended to be greater in human papilloma virus DNA positive cancer patients, compared with human papilloma virus DNA negative cancer patients.

These results suggest that the local laryngeal immune response is activated by infection or carcinogenesis due to human papilloma virus. The findings strongly suggest that secretory IgA has inhibitory activity against infection or carcinogenesis associated with human papilloma virus in the larynx.

To determine the prevalence and type of human papilloma virus deoxyribonucleic acid (DNA) in cases of laryngeal squamous cell carcinoma.

We analysed the prevalence of human papilloma virus infection in archived paraffin block specimens taken from 99 cases of laryngeal squamous cell carcinoma between 1990 and 2005, using polymerase chain reaction techniques. Biopsy specimens from five proven verrucous skin lesions were used as positive controls, and peripheral blood samples from five healthy volunteers were used as negative controls.

Four test samples were found to have inadequate deoxyribonucleic acid purity and were therefore excluded from the study. Human papilloma virus deoxyribonucleic acid was detected in seven of 95 cases of laryngeal squamous cell carcinoma (7.36 per cent). Human papilloma virus genotyping revealed double human papilloma virus infection in three cases and single human papilloma virus infection in the remaining four cases. The human papilloma virus genotypes detected were 6, 11 and 16 (the latter detected in only one case).

In our series, a very low human papilloma virus prevalence was found among laryngeal squamous cell carcinoma cases. The human papilloma virus genotypes detected were mostly 6 and/or 11, and 16 in only one case. To the best of our knowledge, this is the first report of human papilloma virus prevalence in laryngeal squamous cell carcinoma, based on polymerase chain reaction genotyping in a Turkish population.
