Squamous Cell Carcinoma of the Nasal Vestibule: A Multi-Centric Observational Cohort Study.

OBJECTIVES: Squamous cell carcinoma of the nasal vestibule (NV-SCC) is a rare but challenging entity, due to the complex anatomy of the region. Consensus on the best treatment strategy is still lacking, as well as a dedicated staging system. Our aim was to analyze oncological outcomes of surgically treated patients and to investigate possible prognostic factors. METHODS: We performed a retrospective multi-centric observational study including six Academic Hospitals over a 10-year period, including only patients who underwent upfront surgery for primary NV-SCC. Patients were staged according to all currently available staging systems. The Kaplan-Meier method was used to compute overall, disease-free, and disease-specific survival. Logistic regression models were used to correlate between survival outcomes and clinical and pathological variables. RESULTS: Seventy-one patients with a median follow-up of 38 months were included in the study. Partial and total rhinectomy were the most commonly performed procedures, respectively, in 49.3% and 25.4% of cases. Neck dissection was performed on 31% of patients, and 45.1% of them underwent adjuvant radiotherapy. Three years overall, disease-specific and disease-free survival were, respectively, 86.5%, 90.3%, and 74.2%. None of the currently available staging systems were able to effectively stratify survival outcomes. Factors predicting lower overall survival on multivariate analysis were age (p = 0.021) and perineural invasion (p = 0.059), whereas disease-free survival was negatively affected by age (p = 0.033) and lymphovascular invasion (p = 0.019). CONCLUSION: Currently available staging systems cannot stratify prognosis for patients who underwent surgery for NV-SCC. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:2634-2645, 2024.

A single centre's experience of 23 cases of total rhinectomy for the treatment of squamous cell carcinoma involving the nasal vestibule.

PURPOSE: This study aims to analyse the oncological outcomes of total rhinectomy (TR) for squamous cell carcinomas (SCCs) involving the nasal vestibule, and to identify prognostic factors for disease recurrence. METHODS: A retrospective single-centre study was conducted between September 2003 and February 2021 including all patients who underwent a TR for a SCC involving the nasal vestibule. RESULTS: 23 patients were included in the study. Tumours originated from the anterior septum (n = 12), vestibule (n = 8) or skin (n = 3). Six TRs (26.1%) were salvage procedures, after primary radiotherapy or partial rhinectomy. Seven patients had a concurrent neck dissection and 17 patients (73.9%) received adjuvant treatment (14 patients had radiotherapy and 3 had chemoradiotherapy). After a median follow-up of 32 months, six patients (26.1%) presented with tumour recurrence. Three patients (13%) had nodal-only recurrence. The estimated 5-year overall survival, disease-free survival and disease-specific survival were 67.5%, 66.3% and 80.7%, respectively. Positive excision margins were a predictive factor for tumour recurrence (p = 0.0401). CONCLUSION: For SCCs involving the nasal vestibule that are not amenable to limited surgical resection, TR along with adjuvant radiotherapy provide good oncological outcomes and should be considered the main treatment option.

Transoral Laser Surgery for Adenosquamous Carcinoma of the Glottis: First Case Report and Review of the Literature.

Adenosquamous carcinoma of the head and neck is a rare cancer associated with poor prognosis. Histologically, it is identified through the presence of both adenocarcinoma and squamous cell carcinoma, although it may be difficult to diagnose from initial endoscopic biopsies. We report a case of adenosquamous carcinoma of the glottis in an 82-year-old female patient who presented with progressive hoarseness of voice and in whom initial biopsies had shown only moderate to severe dysplasia. This is the first case in the literature of a primary adenosquamous carcinoma of the glottis managed successfully with a CO2 laser left type Va cordectomy. The patient remained disease-free 28 months postoperatively.

Adult-Type Rhabdomyoma of the Larynx in Birt-Hogg-Dubé Syndrome: Evidence for a Real Association.

The autosomal dominant Birt-Hogg-Dubé syndrome is known to be associated with skin, lung and kidney lesions. It is caused by heterozygous germline mutations in the folliculin gene and has a high penetrance. We report the case of a 51 year old woman with Birt-Hogg-Dubé syndrome who presented with a laryngeal mass. Imaging confirmed a mass centered on the piriform sinus and following excision histological examination confirmed the lesion was composed of polygonal cells with abundant eosinophilic cytoplasm consistent with a rhabdomyoma. Laryngeal rhabdomyoma is rare condition and has not been previously described in association with Birt-Hogg-Dubé. In patients with Birt-Hogg-Dubé syndrome who develop upper aerodigestive tract symptoms secondary to mass lesion an adult-type rhabdomyoma might be considered as a differential, with endoscopic excision being the treatment of choice.

Enhanced contact endoscopy for the assessment of the neoangiogenetic changes in precancerous and cancerous lesions of the oral cavity and oropharynx.

Dysplasia and squamous cell carcinoma of the upper aerodigestive tract show significant neoangiogenesis appearing as subepithelial and epithelial microvascular irregularities that can be detected by Image-Enhanced Endoscopy such as Narrow Band Imaging and Storz Professional Image Enhancement System. In the present study, the most advanced endoscopic enhancement systems were coupled with Contact Endoscopy (Enhanced Contact Endoscopy). This original method improved the identification and the understanding of the neoangiogenetic changes of the chorion in 42 patients with leukoplakia, erythroplakia, and leuko-erythroplakia of the oral cavity and oropharynx. The physiologic and pathologic mucosa was described in five obvious vascular patterns observed at Enhanced Contact Endoscopy ranging from normal to squamous cell carcinoma, passing through inflammation, hyperplasia, and dysplasia. Each vascular pattern was then compared to histology, showing that the microvascular architectural changes seen with Enhanced Contact Endoscopy are almost constant. Sensitivity, specificity, positive predictive value, and negative predictive value in the differentiation between healthy mucosa and inflammation versus pathologic hyperplasia, dysplasia, and carcinoma were, respectively, 96.6, 93.3, 98.2, 87.5, and 95.9 %. Sensitivity and specificity were 100 % in differentiation between non-malignant lesions versus squamous cell carcinoma. Our preliminary experience shows that accuracy of Image-Enhanced Endoscopy in the diagnosis of precancerous lesions and squamous cell carcinoma of the oral cavity and oropharynx can be increased if associated to Contact Endoscopy.

Enhanced contact endoscopy for the detection of neoangiogenesis in tumors of the larynx and hypopharynx.

OBJECTIVES/HYPOTHESIS: Image-enhanced endoscopy, such as narrow band imaging and the Storz Professional Image Enhancement System, have been increasingly used in patients with suspect lesions of the larynx and hypopharynx during preoperative and intraoperative assessment. STUDY DESIGN: In the present study, a contact endoscope was coupled with the systems of image-enhanced endoscopy, as to precisely distinguish the peculiar neoangiogenetic changes in inflammation, and precancerous and cancerous lesions of the larynx and hypopharynx. METHODS: We performed a single-blind study with this original approach of a series of 44 patients with different lesions of the larynx and hypopharynx. RESULTS: We observed five obvious vascular patterns matching the diagnosis in 41 patients out of 44, with accuracy in the differential diagnosis between normal tissue and hyperplasia versus mild dysplasia and carcinoma of 97.6%. CONCLUSIONS: Enhanced contact endoscopy allows for predicting histologic changes of laryngeal and hypopharyngeal lesions from inflammation to cancer on based on fine evaluation of the neoangiogenetic changes of the chorion. This innovative procedure can be considered an important tool during diagnosis, treatment, and follow-up of patients with precancer and cancer of the larynx and hypopharynx.

Fourth branchial cleft anomaly: management strategy in acute presentation.

OBJECTIVES: Branchial malformations are common congenital head and neck lesions usually diagnosed in childhood during the first decade of life. Acute presentation is usually managed with conservative protocols before a definitive surgical procedure although the risk of life-treating septic complications may influence the physician's decision. Surgery is the treatment of choice with the removal of the lesion alone, nevertheless more aggressive approaches must be considered in complicated cases. Selective neck dissection including the removal of part of the thyroid lobe with the congenital lesion should be considered as the "ultima ratio" treatment to avoid recurrence. METHODS: We reviewed literature and report our experience concerning two patients with fourth branchial cleft sinus. RESULTS: A three-year-old child with a clinical history of recurrent neck abscess was referred to our department after several drainages performed in another centre. A three-year-old child referred to our department for a left side lower primary neck abscess. In both cases the diagnosis of a complicated fourth cleft remnant was confirmed by rigid endoscopic visualization of the mucosal orifice of the sinus in the pyriform fossa. Surgical management during acute presentation was challenging; in one patient the early fasciitis required an emergency procedure to remove the infected sinus that were strictly adherent to the deep vascular-nervous axis. CONCLUSION: Surgery was the definitive treatment in both cases and at 12 and 25 months follow-up respectively no recurrences were observed.
