Very rare tumour of the palatine tonsil: a molecular approach.

Mucoepidermoid cancer (MEC) is extremely rare in the palatine tonsil with only three adequately described cases in the literature.We describe a woman in her late 70s with vague pharyngeal discomfort who underwent tonsillectomy, lymph node dissection of the neck and radiotherapy for MEC with loco-regional lymph node metastasis of the palatine tonsil. To confirm this extremely rare diagnosis and to gain deeper insight in the molecular oncogenesis, an extensive molecular study including next-generation sequencing and immunohistochemistry was performed. Immunoreactivity for p16 protein and real-time PCR showed high-risk oncogenic human papillomavirus 16 DNA and mutations in the BRAF, BARD and DNMT3A genes. Tumour mutational burden was low. After a follow-up of 7 years the patient is still alive and well without any residual or disseminated disease.

Extranodal follicular dendritic cell sarcoma of the tonsil: An extremely rare clinical entity.

Follicular dentritic cell sarcomatous neoplasms originate from dendritic cells contained within the lymph nodes. In extranodal location, these neoplasms, are rare clinical entities, and even more so, their location in the head-neck region is extremely rare. Only 17 cases of primary dendritic cell sarcoma of the tonsil are reported in the literature at present. Being such a rare entity, histopathological diagnosis can be complex and requires great expertise and proper immunohistochemical analysis [1]. We present a case of a 48-year-old young man diagnosed with follicular dendritic cell sarcoma of the tonsil who underwent, probably for the first time in the literature, transoral robotic surgical resection.

A two-centre experience of tonsil biopsies in the investigation of patients with tonsillar asymmetry.

INTRODUCTION: We aim to evaluate our experience of tonsil biopsies in the investigation of patients presenting with asymmetrical tonsils. METHODS: A two-centre retrospective analysis of all patients who underwent histology sampling of the palatine tonsils between 1 January 2013 and 31 December 2018 was completed. Data collected included patient demographics, method of obtaining tonsil tissue, histological diagnosis and need for repeat tissue sampling. A follow-up period of 36 months was allowed to establish whether any patients re-presented with missed diagnoses. RESULTS: In total, 937 patients were included for analysis: 375 (40.0%) had a biopsy, of which 191 (50.9%) were performed in clinic. The mean duration from initial appointment with the ear, nose and throat clinic to tissue sample collection was 17.6 days (range 0-327 days) for all biopsies, reducing to 0.2 days (range 0-17 days) for biopsies performed in clinic. This was significantly shorter than for tonsillectomies (mean 38.9 days, range 0-444 days; p<0.05). Of the patients who underwent tonsil biopsy, six (1.6%) had malignancy that was not unequivocally diagnosed on initial biopsy. In all six patients, prior clinical suspicion was high, and repeat tissue sampling was undertaken on receipt of negative histology results. CONCLUSIONS: Tonsil biopsy is a viable alternative to tonsillectomy for histology in the assessment of tonsil asymmetry. Tonsil biopsy in the outpatient setting has reduced surgical morbidity, significantly less delay in diagnosis, less inconvenience for patients and lower healthcare costs compared with formal tonsillectomy. Although tonsil biopsies should not be used in isolation, they can be useful in the investigation of patients presenting with tonsillar asymmetry.

Association between tonsillectomy and oropharyngeal cancer risk: a retrospective cohort study.

BACKGROUND: The purpose of this retrospective cohort study is to describe the association between the history of tonsillectomy and the risk of oropharyngeal squamous cell carcinoma (OPSSC), using a large cohort of patients. MATERIALS AND METHODS: We performed a retrospective cohort study with 3620 patients diagnosed with OPٍSCC from 2010 to 2021. We utilized the University of Florida patients' registry i2b2 system. Three subsets of OPSSC were defined, base of tongue(BOT) cancer, tonsillar cancer, and other OPSSC. Tumor demographics and history of tonsillectomy were collected. Odds ratio for OPSSC were assessed utilizing a logistic regression model with adjusting for gender, race, and age. P < 0.05 was deemed significant. RESULTS: Of the 3620 OPSSC patients were BOT cancer (N = 964), tonsillar cancer (N = 995), and other OPSSC (N = 1661). There was a statistically significant reduction in tonsillar cancer and BOT cancer odds ratio in patients with a history of tonsillectomy vs. patients without tonsillectomy (0.086 and 0.117), respectively, with a P value < .0001. The odds ratio of OPSSC in patients with a history of tonsillectomy vs. patients without tonsillectomy is 1.031. CONCLUSION: This study showed that the OPSSC and previous history of tonsillectomy are associated. Our results showed a significant reduction in BOT and tonsillar cancer risk in patients with a history of tonsillectomy and an insignificant decrease in other OPSSC. This study could emphasize the importance of the development of future clinical trials to investigate the role of prophylactic tonsillectomy as a secondary preventive strategy to reduce OPSSC.

Neoadjuvant chemotherapy followed by surgery for HPV-associated tonsillar cancer: Does imaging reflect the pathological response?

OBJECTIVES: The purpose of this study was to present our evaluation of the outcome of tonsillar cancer managed with neoadjuvant chemotherapy followed by surgery as definitive treatment. MATERIALS AND METHODS: Thirty-eight patients with human papilloma virus (HPV)-associated tonsillar cancer were treated with neoadjuvant chemotherapy followed by surgery. The volume reduction response of the tumor to neoadjuvant chemotherapy was evaluated and verified by histopathology. RESULTS: The complete pathologic response (pCR) rates at primary and nodal sites were 60 % and 45 %. Tumor volume reduction ≥78.8 % following neoadjuvant chemotherapy predicted pCR of the cervical node. In addition, the optimal cut-off value to predict pCR at the primary tumor site was 83.4 % volume reduction but was not a significant result. For pCR, neoadjuvant chemotherapy decreased the pathological adverse features, significantly reducing the need for adjuvant therapy. The overall survival of the adjuvant group was 79.2 %, and that of the non-adjuvant group was 87.5 %, with disease-free survival of 65.9 % and 54.2 %. There was no significant difference between the two groups. CONCLUSION: Neoadjuvant chemotherapy followed by surgery proved to be a good therapeutic option for management of HPV-associated tonsillar cancer. A greater reduction in tumor volume in post-neoadjuvant chemotherapy imaging predicts a complete pathologic response.

Leiomyoma of the palatine tonsil - report of a rare and unusual tumor at this site.

A leiomyoma is a remarkably rare cause of a benign, one-side tonsillar enlargement. The diagnosis is essentially histologic and will not normally be suspected clinically. Immunohistochemistry is needed for substantiation of the morphology and confirmation. We submit this illustrative case report.

Oncologic and functional outcomes of neoadjuvant chemotherapy followed by surgery in human papillomavirus-positive tonsillar cancer.

BACKGROUND: Functional outcomes of neoadjuvant chemotherapy in human papillomavirus (HPV)-positive tonsillar cancer remained unclear. METHODS: We retrospectively reviewed the medical records of HPV-positive patients with tonsillar cancer. Of 112 patients, 38 were assigned to a neoadjuvant chemotherapy group and 74 were assigned to an upfront surgery group. RESULTS: Pathological analyses showed that the risks of close or positive resection margins and lymphovascular invasion were lower in patients who received neoadjuvant chemotherapy. The 5-year disease-free survival was significantly higher in the neoadjuvant chemotherapy group than in the upfront surgery group, but the 5-year overall survival was not. The time to commencement of oral feeding and the mean hospital stay were significantly shorter in the neoadjuvant chemotherapy group. The neoadjuvant chemotherapy group was more likely than the upfront surgery group to resume a regular diet. CONCLUSIONS: Compared with upfront surgery, neoadjuvant chemotherapy improved the functional outcomes and 5-year disease-free survival.

Tonsillectomy as Prevention of Tonsil and Base of Tongue Cancer: Systematic Review and Meta-analysis on the Immuno-Oncological Effect of One Among the Most Common Surgeries in the World.

Otorhinolaryngology tradition is that tonsillectomy (TE) is conducted among children and adolescents for obstructive sleep apnea secondary to adenotonsillar hypertrophy and in adults for chronic disease of the tonsils and adenoids (recurrent tonsillitis). Nevertheless, over the last 50 years, we have observed a decline in TE worldwide. As a result, there is an emerging concern of a correlated possible increased risk of tonsil cancer (TC) and other subtypes of oropharyngeal squamous cell carcinoma. Since the available data on such topics are limited and controversial, our aim was to elucidate the impact of TE on the incidence mainly of TC through a systematic review of the literature and a meta-analysis of the studies. After a thorough search, 7 retrospective studies were considered eligible for review and meta-analysis (MA). At MA, patients with a history of TE seem to show a reduced risk of TC but a higher predisposition for base of tongue (BOT) cancer (p<0.001): however, the elevated heterogeneity of the studies hampers drawing firm and convincing conclusions (statistical inconsistency >95%). In future, randomized control trials will be welcome to elucidate the prophylactic role of TE against TC and its real impact on BOT cancer.

Predictive factors of distant metastasis in surgically treated HPV-positive tonsil cancer.

BACKGROUND: Human papilloma virus (HPV)-related tonsil cancer is associated with favorable outcomes. OBJECTIVE: The purpose of this study was to define factors affecting distant metastasis in patients with surgically treated HPV-positive tonsil cancer. METHODS: The present study enrolled 76 patients diagnosed with HPV-positive tonsil cancer who underwent primary surgery between January 2010 and December 2021. RESULTS: Twelve (15.7%) patients experienced a distant failure with a median follow-up time of 43 months. Sites of distant metastasis included the lung (n = 10), liver (n = 1), and brain (n = 1). Upon multivariate analysis, an advanced T stage (odds ratio [OR]: 13.94, 95% confidence interval [CI]: 1.29-149.863, p = 0.003) and margin involvement (OR: 5.96, 95% CI: 1.33-26.76, p = 0.02) were independent predictors of distant metastases. The five-year disease-specific survival for the entire cohort was 85%. The multivariate analysis confirmed that distant metastasis (hazard ratio [HR]: 12.688, 95% CI: 3.424-47.016; p < 0.001) and margin involvement (HR: 6.243; 95% CI: 1.681-23.191; p = 0.006) were significant factors associated with the five-year disease-specific survival. CONCLUSION: HPV-positive tonsil cancer patients with an advanced T stage and a positive surgical margin have a substantial risk of distant metastases. Distant metastasis and margin involvement are factors that affect their survival.

Role of local flaps in the prevention of soft tissue necrosis after transoral robotic surgery for tonsillar cancer.

OBJECTIVE: Soft tissue necrosis (STN) can occur after transoral robotic surgery (TORS) with radiation therapy (RT). We investigated the usefulness of local flap reconstruction for preventing STN after TORS in patients with tonsillar cancer. METHODS: This case-control study retrospectively reviewed clinicopathological data of patients who underwent TORS for tonsillar cancer at a tertiary referral center. The incidence of STN was compared in patients who underwent secondary intention healing or local flap reconstruction, and factors predicting STN were identified. RESULTS: STN occurred in 20 (25%) of 80 patients in the study. The incidence of STN was higher in the secondary intention healing than the flap reconstruction group. Mucositis grade (odds ratio [OR] 3.694, p = 0.02), RT dose (OR 4.667, p = 0.001), and secondary intention healing (OR 14.985, p = 0.035) were predictive factors for STN. CONCLUSION: Flap reconstruction can prevent STN after TORS with RT in patients with tonsillar cancer. The use of local flaps preserves the minimally invasive nature of TORS.

[Tonsillar asymmetry in adults: review of the literature and management algorithm]. / Asymétrie amygdalienne chez l'adulte: revue de littérature et proposition de prise en charge.

Tonsillar asymmetry is both a common clinical finding and a potential sign of cancer. The diagnosis of the latter requires tonsillectomy, which is associated with two weeks off work and post-operative risk of bleeding, which ranges between 1.5 and 15% of the cases. Thus, it is crucial to determine which patients can be followed clinically and which ones will need a diagnostic tonsillectomy. This article provides a review of the literature on tonsillar asymmetry in the adult population and an algorithm for its management.

L'asymétrie amygdalienne est à la fois une découverte clinique fréquente et un potentiel signe de cancer. Le diagnostic de ce dernier se pose par une amygdalectomie. Celle-ci est associée à un arrêt de travail d'environ deux semaines, ainsi qu'à des risques postopératoires de saignement qui varient de 1,5 à 15% des cas. Il est donc crucial de déterminer quels patients peuvent être suivis cliniquement et quels sont ceux qui doivent bénéficier d'une amygdalectomie diagnostique. Cet article propose une revue de la littérature sur l'asymétrie amygdalienne dans la population adulte ainsi qu'un algorithme de prise en charge.

Long-term Locoregional Control With Unilateral Radiation for AJCC-7 T1-2N2b Tonsillar Cancer.

OBJECTIVES: Unilateral radiation to cervical nodes has been used as a de-escalation strategy in well-lateralized tonsil cancers. The efficacy of this approach with multiple ipsilateral nodes is not established. The study hypothesis was that unilateral radiation for American Joint Committee on Cancer (AJCC)-7 T1-2N2b tonsillar cancer results in a low rate of contralateral nodal failure. MATERIALS AND METHODS: This study was a retrospective chart review of patients with AJCC-7 T1-2N2b tonsillar cancer from 2 academic institutions who were treated with unilateral radiation. The primary endpoint was the contralateral nodal failure rate. Locoregional control, overall survival, and the need for gastrostomy tube placement were additional endpoints. RESULTS: The study cohort included 66 patients treated between 2005 and 2016. The median follow-up time was 80.9 months; contralateral nodal failure occurred in 2/66 (3.0%) patients at 4.1 and 20.9 months, respectively. Both patients underwent salvage treatment with long-term subsequent survival. Overall locoregional control at both 2 and 5 years was 93.9% and the median duration of control was not reached. Overall survival at 5 years was 92.4%. CONCLUSIONS: The use of unilateral radiation for AJCC-7 T1-2N2b tonsillar cancer resulted in low rates of contralateral nodal failure. This outcome demonstrates the safety of considering unilateral radiation treatment in patients with a relatively high ipsilateral nodal burden.

Prophylactic contralateral neck dissection has no advantage in patients with early stage HPV-positive tonsil cancer.

BACKGROUND: Patients with locally advanced HPV-positive tonsil cancer would benefit from prophylactic contralateral neck dissection (pCND). AIMS/OBJECTIVES: The aim of this study was to analyze rates of contralateral lymph node metastases (LNM) and their prognostic effects on locally advanced HPV-positive tonsillar squamous cell carcinoma. MATERIALS AND METHODS: Medical records of 54 patients who underwent upfront primary surgery and pCND were retrospectively reviewed. RESULTS: Six (11.1%) patients had contralateral LNM in 54 locally advanced HPV-positive tonsil cancer. Of these, five patients had contralateral level II LNM and one patient had contralateral level II and III LNM. Contralateral LNM showed significant positive correlations with advanced T stage (p = .017) and the presence of extracapsular spread (p = .007). Contralateral lymph node metastasis had no significant association with five-year disease-specific survival. CONCLUSIONS AND SIGNIFICANCE: This study demonstrated no advantage in performing pCND in early stage HPV-positive tonsil cancer.

Synchronous tonsillar tumors with differing histopathology: A case report and review of the literature.

BACKGROUND: Tonsillar squamous cell carcinoma (TSCC) due to human papillomavirus (HPV) infection has seen a dramatic increase in recent years. Bilateral tonsillar squamous cell carcinoma (biTSCC) has a much lower incidence than unilateral TSCC and three main hypotheses of biTSCC pathogenesis prevail: field carcinogenesis, single-clone, and multiple HPV infections. CASE: A 49-year-old Male with a remote history of chewing tobacco presented with symptoms of spitting up tissue and occasional hemoptysis. Physical exam showed a sole left tonsillar mass which was confirmed to be TSCC on biopsy. The patient's computed tomographic (CT) scan was consistent with this finding; however, positron emission tomography (PET) scan indicated a second tumor in the contralateral right tonsil. Surgical resection of both masses and selective neck dissection was performed, and the specimens were sent for further pathological analysis. No complications of surgery were noted and the final diagnosis of synchronous biTSCC was made. The tumors were a T2N0M0 left poorly differentiated TSCC (p16+, EGFR+, bcl2+) with basaloid features, and a T1N0M0 right well to moderately differentiated TSCC (p16+, EGFR+, bcl2-). CONCLUSION: Our present case was notable for differing tumor pathology and karyotype analysis between the right and left masses, directly supporting the multiple HPV infections hypothesis of biTSCC pathogenesis. Further genetic characterization of tonsillar tumors is needed to better characterize TSCC and best guide medical/surgical therapy.

Incidence of synchronous contralateral tonsillar malignancy in a known case of unilateral tonsillar carcinoma.

OBJECTIVE: The literature is divided with regards to contralateral tonsillectomy in a known/suspected case of ipsilateral tonsillar malignancy. In this study, we evaluate the incidence of indolent synchronous contralateral tonsillar malignancy (SCTC) in patients with known ipsilateral tonsillar malignancy. METHODS: All patients diagnosed with ipsilateral tonsillar carcinoma (TC) at a tertiary teaching center between January 2016 and December 2019 were screened. None of the patients were suspected to have bilateral TC. All patients underwent appropriate imaging in the form of Magnetic resonance imaging and computed tomography of head and neck region and then underwent bilateral tonsillectomy. The prevalence of bilateral tonsillar malignancy and the factors predicting them were analyzed. RESULTS: In all 59 patients were included in the study. The mean and median age of the patient population was 60.8 and 59 years, respectively, with a male to female ratio of 3.2:1. The incidence of bilateral tonsillar malignancy in carcinoma of unknown primary (CUP) was 3/10 (33.3%). Among the remaining 49 patients, incidence of synchronous contralateral tonsillar carcinoma (SCTC) was 2/49 (4.08%). Overall, 5/59 (8.5%) patients had synchronous bilateral tonsillar malignancy. Furthermore, dysplasia was found in the contralateral tonsil in 4/10 (40%) CUP patients. Among the remaining 49 patients, dysplasia was seen in the contralateral tonsil in 20/49 (40.8%) patients. The absence of p16 expression predicted higher probability of SCTC. Factors like gender, T stage, nodal status or smoking did not predict SCTC. CONCLUSION: We recommend bilateral tonsillectomy in all patients with suspected or proven TC (unilateral or bilateral) and CUP as it helps identify indolent SCTC and it does not add any significant morbidity to the patients. LEVEL OF EVIDENCE: III.

Primary Closure With Posteriorly Based Lateral Tongue Flap Reconstruction After Transoral Videolaryngoscopic Surgery for Tonsil Cancer.

INTRODUCTION: Transoral surgery for head and neck cancer provides excellent oncologic outcomes while preserving speech and swallowing function. When neck dissection and resection of oropharynx are performed concomitantly, there is a risk of creating a communication defect or developing a pharyngocutaneous fistula. To prevent pharyngocutaneous fistula, we performed the reconstruction using a posteriorly based lateral tongue flap for communication defect. PATIENT: A 72-year-old male with oropharyngeal cancer (tonsil cancer) T2N1M0 underwent concomitant transoral videolaryngoscopic surgery and neck dissection. The lateral wall of the oropharynx was resected with the pharynx constrictor muscle and parapharyngeal fat due to infiltration of the parapharyngeal space by the tonsil cancer. The posteriorly based lateral tongue flap was used to close the perforation. There was no leakage to the neck postoperatively. The patient had no problem with phonation or oral intake and remained free of disease at 12 months after treatment. CONCLUSION: For a small defect confined to the oropharyngeal lateral wall, the posteriorly based lateral tongue flap should be considered as a useful option for reconstruction of the oropharynx without impairment of posterior function.

Trans-oral robotic surgery for head and neck cancers using the Medrobotics Flex® system: the Adelaide cohort.

Trans-oral robotic surgery for head and neck cancers can be performed using rigid, multi-port robots with linear access but the Medrobotics Flex® system offers an alternative as it is endo-luminal, single-port, and uses flexible instruments. To assess the utility of the Medrobotics Flex® system for head and neck cancer (HNC) resections. A retrospective review of all HNC resections done over a 2.5-year period (Jan 2017-July 2019) at the Memorial Hospital, using the Flex® system. Data collected include patient demographics, tumour site, tumour stage, p16 status, smoking history, surgery performed, histologic margins, complications, overall survival, recurrence, and adjuvant treatments received. There were 49 head and neck cancer cases in total done using the Medrobotics Flex® system. Median age 60 years, with M:F ratio 3.5:1. Outcomes: oropharyngeal cancers (82%), p16 positive (89%), overall survival (94%), local recurrence (6%), and adjuvant treatment (84%). Cancer procedures done included lateral oropharyngectomy (43%), tongue base mucosectomy (27%), tongue base resection (18%), and others (12%) which include a single case each of supraglottic laryngectomy, hypopharyngeal tumour resection, partial pharyngectomy, partial glossectomy, and vocal cord tumour resection. Clear margins were related to tumour T stage and achieved for T1 tonsil cancer (75%), T2 tonsil cancer (70%), T3 tonsil cancer (50%), T1 tongue base cancer (80%), and T2 tongue base cancer (66.7%). Median operating time with neck dissection was 2 h 40 min, whilst median length of hospital stay was 1 day (IQR 1-7 days). Complications included a single case each of secondary haemorrhage (managed conservatively), oro-cervical fistula, wound infection, tongue numbness, and a medical event. There was no primary haemorrhage and no mortality. The Medrobotics Flex® system is a safe and reliable tool for head and neck cancer surgery.

Second Primary Tumors in Patients Presenting With Unilateral HPV-Associated Tonsillar Squamous Cell Carcinoma.

OBJECTIVE: To describe and compare rates of metachronous and synchronous second primaries of the contralateral tonsil in patients with primary HPV(+) tonsillar squamous cell carcinoma (SCC). STUDY DESIGN: Retrospective cohort study. MATERIALS AND METHODS: This is a single tertiary care center retrospective case series, from 2006 to 2019, of HPV(+) tonsillar SCC patients who underwent primary surgical resection with unilateral wide-field tonsillectomy or bilateral tonsillectomy for diagnostic or therapeutic purposes. A metachronous second primary is one diagnosed >6 months after completion of surgical treatment. A synchronous second primary is one diagnosed during bilateral tonsillectomy for unilateral HPV(+) tonsillar SCC. Rates of second primary and patient characteristics were compared using chi-square tests. RESULTS: About 303 patients underwent unilateral surgical resection +/- adjuvant therapy for HPV(+) tonsillar SCC. One (0.3%) developed a metachronous second primary in the contralateral tonsil 11.9 years following treatment. Fifty-seven patients with HPV(+) tonsillar SCC underwent bilateral tonsillectomy, and 37/57 (65%) had no clinical signs for contralateral disease. Of these, only 1/37 (2.7%) was incidentally found to have a synchronous second primary. Twenty patients underwent bilateral tonsillectomy due to clinical concern for contralateral disease. Of these, 3/20 (15%) were found to have a synchronous HPV(+) SCC in the contralateral tonsil. CONCLUSIONS: The prevalence of metachronous second primary after appropriate treatment of HPV(+) tonsillar SCC is very low (0.3%) and so is the chance of incidentally discovering a synchronous second primary during bilateral tonsillectomy (2.7%). We do not recommend bilateral tonsillectomy as a part of the routine algorithm in the surgical management of these patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:332-338, 2022.

Swallowing After Primary TORS and Unilateral or Bilateral Radiation for Low- to Intermediate-Risk Tonsil Cancer.

OBJECTIVE: The primary course of treatment for patients with low- to intermediate-risk tonsil cancer has evolved with a shift toward primary transoral robotic surgery (TORS) or radiation therapy (RT). While favorable outcomes have been reported after deintensification via unilateral TORS or RT (uniRT), comparisons of functional outcomes between these treatments are lacking. We compared clinical outcomes (Dynamic Imaging Grade of Swallowing Toxicity [DIGEST] and feeding tube [FT]) and patient-reported swallowing outcomes (MD Anderson Dysphagia Inventory [MDADI]) based on primary treatment strategy: TORS, uniRT, or bilateral RT (biRT). STUDY DESIGN: Secondary analysis of prospective cohort. SETTING: Single institution. METHODS: The study sample comprised 135 patients with HPV/p16+ T1-T3, N0-2b (American Joint Committee on Cancer, seventh edition), N0-1 (eighth edition) squamous cell carcinoma of the tonsil were sampled from a prospective registry. Modified barium swallow studies graded per DIGEST, FT placement and duration, and MDADI were collected. RESULTS: Baseline DIGEST grade significantly differed among treatment groups, with higher dysphagia prevalence in the TORS group (34%) vs the biRT group (12%, P = .04). No significant group differences were found in DIGEST grade or dysphagia prevalence at subacute and longitudinal time points (P = .41). Mean MDADI scores were similar among groups at baseline (TORS, 92; uniRT, 93; biRT, 93; P = .90), subacute (TORS, 83; uniRT, 88; biRT, 82; P = .38) and late time points (TORS, 86; uniRT, 86; biRT, 87; P = .99). FT placement and duration significantly differed among primary treatment groups (FT [median days]: TORS, 89% [3]; uniRT, 8% [82]; biRT, 37% [104]; P < .001). CONCLUSION: While TORS and uniRT offer optimal functional outcomes related to dysphagia, results suggest that no measurable clinician-graded or patient-reported differences in swallow outcomes exist among these primary treatment strategies and biRT. Aside from baseline differences that drive treatment selection, differences in FT rate and duration by primary treatment strategy likely reflect diverse toxicities beyond dysphagia.

Fibroepithelial polyp of palatine tonsil: a case report.

Fibroepithelial polyps represent a frequent cutaneous lesion of mesodermal origin, with a prevalence of 1.2% and are rarely located at palatine tonsils. We present a rare clinical report of a 70-year-old female patient with fibroepithelial polyp of palatine tonsil. This entity represents the eighth case of palatine tonsil fibroepithelial polyp in the English literature. She presented with a polypoid mass at the right tonsil and unspecified throat symptoms. Physicians should pay attention to such lesions because of the residual risk of malignant transformation, along with non-specific symptoms. Differential diagnosis was among neurofibroma, lipoma, squamous papilloma and fibroepithelial polyp. Histopathological examination following tonsillectomy showed a structure rich in vesicles inside lamina propria and surrounding inflammation, establishing the diagnosis of a fibroepithelial polyp. It requires vigilance during complete clinical examination, in order to detect masses at patients with throat symptoms that could have remained undiagnosed until they become even life threatening.
