RESUMO
BACKGROUND: Synovial sarcoma is a rare soft tissue malignancy, occasionally found in the head and neck region. The diagnosis necessitates a multidisciplinary approach involving the clinical presentation, proper imaging studies and histological confirmation, with molecular testing for definitive identification. Treatment entails surgical resection with adjuvant therapies as needed. CASE PRESENTATION: A 33-year-old male patient presented with globus sensation concomitant with right-sided neck swelling. He was clinically found to have right tonsil enlargement with posterior extension. Therefore, he underwent right tonsillectomy with pharyngoplasty. Histopathological examination revealed a biphasic tumor consistent with synovial sarcoma, confirmed by immunohistochemistry and fluorescence in situ hybridization. CONCLUSIONS: Tonsillar synovial sarcoma represents a diagnostic challenge, requiring a high index of suspicion and comprehensive evaluation. With only twenty previously published cases documented in the literature, awareness of this rare presentation is crucial for prompt diagnosis and appropriate management. Collaboration among multidisciplinary healthcare teams and ongoing research efforts are essential for optimizing diagnostic accuracy, treatment efficacy, and patient outcomes in this rare malignancy.

BACKGROUND: Extranodal natural killer/T-cell lymphoma (ENKTL) with tonsil involvement is not common, especially in children. CASE PRESENTATION: A 13-year-old girl presented with an unexplained sore throat for more than 2 months, together with intermittent fever and suppurative tonsilitis. Nasopharyngoscopy revealed a pharyngeal mass. Enhanced computed tomography (CT) scan showed tonsillar hypertrophy and punctate calcification. Chronic pyogenic granulomatous inflammation with pseudoepithelial squamous epithelial hyperplasia was observed in left tonsil, and pyogenic granulomatous inflammation and a small number of T-lymphoid cells were detected in the right tonsil. The immunohistochemical results showed CD2+, CD3+, CD4+, CD5+, CD8+, granzyme B+, and TIA-1+. The Ki-67 proliferation index was 20%. The case showed T cell receptor gene rearrangement. Finally, the case was diagnosed as ENKTL of stage II with tonsil involvement. The patient received 6 cycles of chemotherapy with SMILE regimen, and showed complete response with no recurrence in the follow-up. CONCLUSION: We presented a rare case of ENKTL with tonsil involvement in a child. The patient showed complete response to the SMILE chemotherapy with no recurrence.

Objectives: To analyze the location, discovery time and possible causes of cases of cervical cystic lymph node metastasis with an unknown primary misdiagnosed as branchial cleft carcinoma. Methods: A retrospective analysis was performed on clinical and pathological data of 15 patients misdiagnosed as branchiogenic carcinoma at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2000 and December 2020. Results: Among the 15 patients, 6 were nasopharyngeal squamous cell carcinoma, 4 tonsil squamous cell carcinoma, 2 tongue root squamous cell carcinoma, 2 hypopharyngeal squamous cell carcinoma and 1 thyroid papillary carcinoma. The median time from the diagnosis of branchial cleft carcinoma to the discovery of primary lesions was 3.58 months (0-76 months). The causes of misdiagnosis might be the lack of experience in the diagnosis and treatment of branchial cleft carcinoma, and not enough attention to comprehensive examination and close follow-up. Conclusions: Different from oropharyngeal cancer reported internationally, the proportion of misdiagnosed cases with nasopharyngeal carcinoma as the primary site in the current article is higher. As a country with a high incidence of nasopharyngeal carcinoma, the examination of nasopharynx should not be taken lightly. Most hidden cases can be found in the comprehensive examination in a short time, while a few cases need long-term follow-up. Finding the primary sites should not rely too much on imaging examination, and we cannot ignore the importance of clinical physical examination.

ABSTRACT: Radiation therapy is often accompanied by skin toxicity in the irradiated area and radiation-induced DNA damage to skin tissue cells in the surrounding pigmented area. This case report describes a patient with radiation-induced skin injury who received wound treatment and psychological intervention with satisfactory results. A 60-year-old woman was admitted to the authors' hospital on January 18, 2021, with radiation-induced skin injury caused by carbon ion radiotherapy for tonsillar carcinoma. The patient underwent wound repair combined with psychological intervention (30 minutes per dressing change). Over a period of 1 month, the wound area was reduced from 11 × 12 cm2 to 1 × 1 cm2, and wound symptoms (exudate, blood odor, wound infection, wound edge dehydration and curling, periwound skin peeling, dryness, and hyperkeratosis) improved. The patient's anxiety factor scores decreased from 18 to 1, and her depression factor scores decreased from 16 to 3. When the patient was discharged from the hospital after 1 month of treatment, she had a satisfactory self-image and normal social activities.

Objective: To analyze the ultrasonic features of tonsillar lymphoma to improve the diagnostic accuracy. Methods: The clinical, pathological and ultrasonic data of nine patients with tonsillar lymphoma confirmed by pathology at Tianjin Medical University Cancer Institute and Hospital during June 2015 and June 2022 were analyzed retrospectively, and the characteristics of their ultrasonic images were summarized. Results: All 9 cases of tonsil lymphoma were unilateral tonsil disease, including 4 cases on the left side and 5 cases on the right side. The average maximum diameter of tonsil lymphoma in 9 cases was 4.32 cm. There were 3 cases with simultaneous involvement of tonsil and cervical lymph nodes, all of which were ipsilateral lymph nodes. Gray scale ultrasound showed that the lesions were hypoechoic, with clear boundaries in 7 cases and unclear boundaries in 2 cases. The shape was full and irregular in 5 cases and oval in 4 cases. The echo was uniform in 7 cases and uneven in 2 cases. Color Doppler ultrasonography showed abundant internal blood flow signal in 1 case, a little dotted linear internal blood flow signal in 5 cases, and no obvious internal blood flow signal in 3 cases. Conclusions: The ultrasonic features of tonsillar lymphoma include hypoechoic area, clear boundary, full shape, irregular and uniform internal echo, no or low linear signal of internal blood flow. Ultrasonography is of great value in the diagnosis of this disease and can help clinical decision-making.

Osteonecrosis of the jaw is a recognized complication associated with bevacizumab. Here, we present a patient with squamous cell carcinoma of the tonsil who experienced minimal skin fibrosis following intensity-modulated radiation therapy. Subsequently, the patient developed rectal adenocarcinoma and encountered osteonecrosis of the jaw after receiving two cycles of bevacizumab. Close monitoring, accompanied by thorough examination to detect early signs of osteonecrosis of the jaw, should be considered for patients who have undergone radiation therapy in the head and neck region and are receiving bevacizumab or other medications known to be associated with osteonecrosis of the jaw.

BACKGROUND: This study aimed to compare the diagnostic value of [68 Ga]Ga-DOTA-FAPI-04 and [18F]FDG PET/CT imaging for primary lesions and metastatic lymph nodes in patients with tonsil cancer. METHOD: Twenty-one tonsil cancer patients who underwent [68 Ga]Ga-DOTA-FAPI-04 and [18F]FDG PET/CT scans within two weeks in our centre were retrospectively enrolled. The maximum standardized uptake value (SUVmax) and tumor-to-background ratio (TBR) of the two tracers were compared by using the MannâWhitney U test. In addition, the sensitivity, specificity, and accuracy of the two methods for diagnosing metastatic lymph nodes were analysed. RESULTS: In detecting primary lesions, the efficiency was higher for [68 Ga]Ga-DOTA-FAPI-04 PET/CT (20/22) than for [18F]FDG PET/CT (9/22). Although [68 Ga]Ga-DOTA-FAPI-04 uptake (SUVmax, 5.03 ± 4.06) was lower than [18F]FDG uptake (SUVmax, 7.90 ± 4.84, P = 0.006), [68 Ga]Ga-DOTA-FAPI-04 improved the distinction between the primary tumor and contralateral normal tonsillar tissue. The TBR was significantly higher for [68 Ga]Ga-DOTA-FAPI-04 PET/CT (3.19 ± 2.06) than for [18F]FDG PET/CT (1.89 ± 1.80) (p < 0.001). In lymph node analysis, SUVmax and TBR were not significantly different between [68 Ga]Ga-DOTA-FAPI-04 and [18F]FDG PET/CT (7.67 ± 5.88 vs. 8.36 ± 6.15, P = 0.498 and 5.56 ± 4.02 vs. 4.26 ± 3.16, P = 0.123, respectively). The specificity and accuracy of [68 Ga]Ga-DOTA-FAPI-04 PET/CT were higher than those of [18F]FDG PET/CT in diagnosing metastatic cervical lymph nodes (all P < 0.05). CONCLUSION: The availability of [68 Ga]Ga-DOTA-FAPI-04 complements the diagnostic results of [18F]FDG by improving the detection rate of primary lesions and the diagnostic accuracy of cervical metastatic lymph nodes in tonsil cancer compared to [18F]FDG.

Objective: Studies have demonstrated that tonsillectomy may alter the risk of oropharyngeal cancer (OPC). We systematically reviewed the evidence and pooled data to examine such an association. Methods: PubMed, Embase, and Scopus were searched up to 25th April 2023. Studies reporting an association between tonsillectomy and oropharyngeal cancer risk at any site were included. Results: Five studies were eligible. All examined the risk of tonsillar and base of the tongue (BOT) cancer with prior history of tonsillectomy. On meta-analysis of the data, prior history of tonsillectomy was associated with a significantly decreased risk of tonsillar cancer. The second meta-analysis showed that history of tonsillectomy did not significantly alter the risk of BOT cancer. However, after exclusion of one study, the results showed an increased risk of BOT cancer with a history of tonsillectomy. Conclusions: The scarce data available in the literature suggests that tonsillectomy may reduce the risk of tonsillar cancer but does not alter the risk of BOT cancer. Further studies are needed to explore the association between tonsillectomy and the risk of OPC.

Objective: To evaluate the efficacy of neoadjuvant chemoimmunotherapy (NACI) combined with transoral robotic surgery (TORS) in the treatment of locally advanced oropharyngeal squamous cell carcinoma (OPSCC). Methods: This was a retrospective study of 15 patients with locally advanced OPSCC who underwent TORS after neoadjuvant therapy (NAT) at the Department of Otolaryngology-Head and Neck Surgery of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from April 2019 to February 2023. There were 12 males and 3 females, aged 31 to 74 years. Twelve cases were tonsil cancer, and 3 cases were tongue base cancer. There were 11 cases in stage â ¢ and 4 cases in stage â £. Two patients received neoadjuvant chemotherapy and 13 patients received NACI, with 2 to 3 cycles, and all patients underwent TORS after multidisciplinary team consultation. The clinicopathological characteristics, surgical outcomes, and oncological results were summarized. Results: All surgeries were successfully completed with negative surgical margins, and no case was required conversion surgery. All patients were fed via nasogastric tubes postoperatively, with a median gastric tube stay of 7 days (range: 2-60 days). No tracheotomy was applied. There were no major complications such as postoperative bleeding. Pathological complete response (pCR) was found in 10 cases (76.9%) among the 13 patients with NACI. The follow-up time was 21 months (range: 10-47 months), and there was no death or distant metastasis. One patient with rT0N3M0 tonsil cancer had local recurrence 5 months after surgery. The 2-year overall survival and 2-year disease-free survival were respectively 100.0% and 93.3% in the 15 patients. Conclusion: NACI combined with TORS provides a safe, effective and minimally invasive treatment for patients with locally advanced oropharyngeal squamous cell carcinoma.

ABSTRACT: Malignant basaloid neoplasms of the skin are frequent, and their accurate diagnosis holds paramount importance for treatment and prognosis. However, these neoplasms can present diagnostic challenges because of their extensive differential diagnosis, which encompasses cutaneous metastasis among many other possibilities. We present a case of a 74-year-old man with a history of p16-positive palatine tonsil squamous cell carcinoma (SCC) treated with surgery and adjuvant radiation with no prior evidence of recurrence who presented to the dermatologist with 2 chin papules. The initial histopathologic evaluation of these lesions showed poorly differentiated malignant basaloid neoplasms. Subsequently, these biopsies were compared with the previous biopsies from his tonsil and lymph node, which showed similar findings including positive p16 staining and positive molecular testing for human papillomavirus-16, confirming the diagnosis of cutaneous metastasis from his previously diagnosed human papillomavirus-related tonsil SCC. Additional imaging studies found metastases to internal organs including the brain, and he was started on chemotherapy, immunotherapy, and radiation therapy. Cutaneous metastases from tonsil SCC are exceedingly rare, and only 5 cases have been described. Furthermore, this is the first case confirming the presence of high-risk human papillomavirus by molecular studies within the cutaneous metastases. The presented case underscores the importance of recognizing this unusual manifestation of tonsil SCC metastatic to the skin along with a good clinical patient history, ensuring accurate and prompt diagnosis and treatment of this condition.

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.

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.

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.

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 OPÙSCC 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.

This case report elucidates an uncommon manifestation of toxoplasmosis characterized by an ulcerative oropharyngeal lesion and cervical lymphadenopathy, which intriguingly simulated a tonsillar neoplasm. The patient, a 28-year-old immunocompetent woman, reported symptoms such as a persistent sore throat, unilateral neck pain, and otalgia. Despite the initial clinical impressions, a diagnostic left subtotal tonsillectomy revealed no malignancy but marked acute and chronic inflammation. A comprehensive investigation subsequently indicated a recent primary infection with Toxoplasma gondii, as evidenced by the presence of high IgM antibodies and low IgG avidity. This unique case underlines the significance of incorporating toxoplasmosis into the differential diagnosis of oropharyngeal lesions, thereby necessitating a meticulous approach to laboratory testing.

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.

Osteoradionecrosis (ORN) is a rare but serious late complication of head and neck radiation therapy. The mandible, proximity of the primary tumor to the jawbones, radiation dose, poor oral hygiene, and smoking history are risk factors of ORN. ORN manifests as a chronic infection with exposed jawbone, which typically occurs in the first 3 years after radiotherapy; however, the risk for ORN development occurring in the patients who have undergone head and neck radiation therapy may be indefinite. Surgery has an important role in the management of cases of ORN, ranging from sequestrectomy, debridement, and extensive extirpative procedures with reconstructive surgery.

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.
