“…1D). On microscopic evaluation, the tumour fulfilled Enzinger and Weiss's diagnostic criteria for schwannoma: (1) presence of a capsule, (2) presence of Antoni A and/or Antoni B areas, and (3) positivity of S-100 reaction 2 3 . Furthermore, Verocay bodies were visible and no interspersed axons were present.…”

“…On laryngoscopy, a laryngeal schwannoma appears like a submucosal mass. Paralysis or hypomobility of the ipsilateral vocal cord can be present 2 3 . The very slow growth (in the order of years), the absence of pathological lymphadenopathy and the lack of weight loss are characteristics indicating the benignity of this neurogenic tumour.…”

“…For voluminous tumours, an external approach may offer the best exposure for complete extra-capsular excision in a single block and allow preservation of the laryngeal mucosa while minimising complications and maximising postoperative voice outcome 1 . The most frequently used open approaches are the median thyrotomy 2 6 and lateral thyrotomy 1 3 . Recently, Ueha et al proposed a suprathyroid alar cartilage approach (STACA) for submucosal laryngeal tumours that includes sacrifice of the ipsilateral prelaryngeal muscles, a larger lateral incision of thyrohyoid membrane and tracheostomy 9 .…”

Gli schwannomi laringei sono una variante estremante rara dei tumori benigni della laringe. Riportiano il caso di un voluminoso schwannoma localizzato nella regione sopraglottica, con coinvolgimento dello spazio pre-epiglottico e paraglottico superiore. I segni e i sintomi di presentazione di tale tumore e le principali caratteristiche radiologiche riscontrabili alla TC e alla RMN sono descritte dettagliatamente. Pur non permettendo una diagnosi certa, tali caratteristiche, tipiche ma non esclusive dello schwannoma, sono importanti per sospettare il tumore in fase preoperatoria. La diagnosi definitiva necessita comunque dellesame istologico e immunoistochimico, ottenibile mediante biopsia escissionale. Nello specifico descriviamo lutilizzato nuovo approccio open mini-nvasivo che consente di ottenere la exeresi completa del tumore, con un ottimo outcome funzionale.

“…Most authors favor external approaches with alternative airway provisions such as a preliminary tracheotomy in larger tumors. Median or lateral thyrotomy or median or lateral pharyngotomy are recommended [1,[8][9][10][11][12]. In smaller tumors, endoscopic (laser-assisted) resection of the tumor can be a reasonable treatment option [1,13].…”

Introduction: The plexiform neurofibroma is a rare benign tumor which is often associated to type 1 neurofibromatosis or Von Recklinghausen's disease. The laryngeal involvement in neurofibromatosis is extremely rare. The objective of our report is the consideration of laryngeal neurofibromatosis in the differential diagnosis of dyspnea in infants and children. Summary of the clinical case: We report the case of a 4 year-old child who presented with inspiratory dyspnea. Laryngoscopy revealed a mass obstructing completely the laryngeal vestibule. Pathological examination of the resected tissue revealed a plexiform neurofibroma after immunohistochemical examination. The patient had regular follow up and she remained symptom free. Discussion: There is an association between neurofibromatosis type 1 and plexiform neurofibromas of the larynx. Analysis of the margins of neurofibromas of the larynx associated with neurofibromatosis type 1 may help predict clinical behavior.

“…However, this method may not be suitable for every patient due to anatomical constraints and the requests of patients (15). There are a number of surgical methods that may be used, including trans-oral microlaryngoscopic excision, median thyrotomy and lateral pharyngotomy.…”

Schwannomas are benign encapsulated tumors arising from Schwann cells in the peripheral nervous system. Between 25 and 45% of schwannomas occur in the head and neck region. Schwannomas of the larynx are extremely rare with an incidence of 0.1–1.5% in all benign laryngeal tumors. Laryngeal schwannomas usually occur in females aged between their 4th and 5th decades. The most successful curative method is surgical resection. When selecting the surgical method, the size and location of the tumor, as well as the requests of the patient, should be considered. The present case report describes a 29-year-old female patient with symptoms of hoarseness and dyspnea on exertion. Through endoscopic biopsy, histopathology revealed a schwannoma. Considering the symptoms, age and preferences of the patient, the method of trans-oral microlaryngoscopic excision without tracheotomy was used to excise the tumor located in the aryepiglottic fold. Results from a short-term follow-up showed the postoperative result to be satisfactory.
