“…Recurrent respiratory papillomatosis (RRP) is an aggressive upper airway disease characterized by rapidly growing benign epithelial lesions that result from infection with human papillomavirus (HPV) [ 1 , 2 , 3 ]. Around 95% of RRP lesions are HPV positive, and around 85% are positive for low-risk mucosal types 6 and/or 11 alone [ 4 ]. The larynx and specifically the vocal folds are most often affected [ 5 ].…”

Recurrent respiratory papillomatosis (RRP), caused by laryngeal infection with low-risk human papillomaviruses, has devastating effects on vocal communication and quality of life. Factors in RRP onset, other than viral presence in the airway, are poorly understood. RRP research has been stalled by limited preclinical models. The only known papillomavirus able to infect laboratory mice, Mus musculus papillomavirus (MmuPV1), induces disease in a variety of tissues. We hypothesized that MmuPV1 could infect the larynx as a foundation for a preclinical model of RRP. We further hypothesized that epithelial injury would enhance the ability of MmuPV1 to cause laryngeal disease, because injury is a potential factor in RRP and promotes MmuPV1 infection in other tissues. In this report, we infected larynges of NOD scid gamma mice with MmuPV1 with and without vocal fold abrasion and measured infection and disease pathogenesis over 12 weeks. Laryngeal disease incidence and severity increased earlier in mice that underwent injury in addition to infection. However, laryngeal disease emerged in all infected mice by week 12, with or without injury. Secondary laryngeal infections and disease arose in nude mice after MmuPV1 skin infections, confirming that experimentally induced injury is dispensable for laryngeal MmuPV1 infection and disease in immunocompromised mice. Unlike RRP, lesions were relatively flat dysplasias and they could progress to cancer. Similar to RRP, MmuPV1 transcript was detected in all laryngeal disease and in clinically normal larynges. MmuPV1 capsid protein was largely absent from the larynx, but productive infection arose in a case of squamous metaplasia at the level of the cricoid cartilage. Similar to RRP, disease spread beyond the larynx to the trachea and bronchi. This first report of laryngeal MmuPV1 infection provides a foundation for a preclinical model of RRP.

“…Symptoms are similar to those of inflammatory sinonasal diseases and thus diagnosis may delay significantly. Poor prognosis with approximately 50-60% 5-year survival rate is mostly attributed to the advanced stage at presentation [1,2,4].…”

Purpose of reviewTo assess the impact of benign and malignant sinonasal tumors and their management on patients' Quality of Life (QOL) as measured by Patient Reported Outcome Measures (PROMS). Recent findingsAlthough there is a growing consensus that endoscopic surgical management in carefully selected patients with sinonasal tumors is at least as (and probably more) effective than open resection, it is not clear to what extent this translates to better QOL outcomes. Earlier studies reported better outcomes in the emotional and physical function domains after endoscopic resection, and it seems that postsurgical morbidity is less in endoscopic compared to open approaches. QoL after endoscopic surgery for sinonasal and anterior skull base tumors seems to improve within several months of surgery in both benign and malignant tumor groups. However, patients with benign sinonasal tumors have a higher QOL pre and post operatively compared to those with malignancy mainly due to absence of (neo) -adjuvant radiotherapy and/or chemotherapy. Factors that seem to be associated with worse QoL include > 60 years, less than 6 months from surgery, prior and adjuvant chemo and radiotherapy, smoking history, advanced staging and malignancy. SummaryThere is not a universally accepted PROM for use in patients with sinonasal benign and malignant tumors: A variety of different PROMs have been used with different degrees of effectiveness. Most likely a combination of disease-specific (such as SNOT 22 and anterior skull base questionnaire) and generic (such as Short Form health survey questionnaire (SF-36) and Karnofsky Performance Status) health outcome measures provide the most insight into QOL of patients with sinonasal tumors. QOL of these patients appears to undergo a bimodal impact with patients experiencing an initial dip in QOL after surgical treatment followed by a slow improvement over time. However, while patients with benign tumors' return to their status quo ante QOL, this is not the case for patients with malignant tumors who stabilize at a lower than initially QOL. To a large extent this seems to be the effect of (neo) adjuvant chemo radiotherapy.

“…Most of these lesions are solitary (85%) small (between 2 and 6 mm), and located in the distal esophagus (70%) [7]. Diagnostic confirmation is made by biopsy and histopathological study, which shows thickened, acanthotic, squamous epithelium forming finger-like papillary projections with fibrovascular centers; without invasion of the submucosa [4].…”

Background. Esophageal squamous cell papillomas are rare epithelial lesions with malignant potential, diagnosed by upper gastrointestinal endoscopy. Their prevalence is from 0.01% to 0.43%. Objective. Description of rare esophageal squamous papilloma diagnosed during upper gastrointestinal endoscopy. Material and methods. A 38-year-old asymptomatic female patient underwent an upper gastrointestinal endoscopy. A growth described as an "esophageal polyp" was detected. The biopsy was performed and specimens were sent for histopathological study. Results. The final diagnosis of esophageal squamous papilloma was made due to histopathological study. Because of the malignant potential of these lesions, once diagnosed, early treatment is essential to prevent progression to esophageal carcinoma. Conclusions. Esophageal squamous papillomas are increasing in prevalence and have been shown to be potentially malignant. This argues the relevance of the problem and the need for widespread immunizations to control human papillomavirus infection.
