“…10 Piecemeal resection is also associated with recurrence. 27 Malignant transformation of schwannoma is very uncommon, and its risk is much lower than that of neurofibroma. 3,13,16 Notably, as summarized by Tulli et al., 10 schwannoma with extralaryngeal extension is associated with neurofibromatosis type 2 or schwannomatosis.…”

Neurogenic tumors located in the larynx are extremely rare. Among them, schwannoma is a benign encapsulated tumor originating from Schwann cells, which form nerve fiber sheaths in the peripheral nervous system. We herein report a case of a schwannoma arising from a rare subsite of the larynx and review the literature on laryngeal schwannoma. The case involved a woman with a 1-month history of globus pharyngeus and dysphagia without dysphonia. Rigid laryngoscopy and magnetic resonance imaging showed a large submucosal bulge toward the medial wall of the right pyriform fossa, pushing the right false and true vocal cords and aryepiglottic fold inward. A transcervical approach was used to completely excise the tumor without incisional biopsy or preliminary tracheotomy. Histology confirmed a benign schwannoma originating from the right paraglottic space, which was extremely rare. During follow-up, no evidence of recurrence or a residual mass was found. The transcervical approach is a useful and less invasive treatment for laryngeal schwannoma located in the paraglottic space.

“…Computed tomography and/or magnetic resonance imaging can provide the size and extend of the tumor, but the diagnosis of neurilemmoma can only be confirmed with histopathology 6,7. Surgical resection is the only standard treatment of neurilemmoma, and many different surgical approaches have been described previously 8–10. Excluding the factors of surgical approach, the methods of the tumor resection can be roughly divided into 2 categories.…”

Background: Laryngeal neurilemmoma, especially recurrent laryngeal neurilemmoma, is a rare neural sheath tumor in head and neck. The most common symptom of laryngeal neurilemmoma is hoarseness or dysphonia, followed by dysphagia, dyspnea, and foreign body sensation. At present, surgical resection is the most effective treatment for this kind of tumor, thus making how to remove it become the most concerned problem of surgeons. Case Presentation: On February 18, 2021, a 64-year-old male presented to our clinic with recurrent sore throat and intermittent hoarseness for 3 years. The results of electronic laryngoscope and magnetic resonance imaging showed a 25×10×21 mm well-defined tumor in the left pyriform sinus without laryngeal cartilage destruction and enlarged lymph nodes. After the initial diagnosis of recurrent laryngeal neurilemmoma, to preserve the continuity of recurrent laryngeal nerve as much as possible, the authors determine to perform anatomical resection of recurrent laryngeal neurilemmoma with operating microscope under the monitoring of recurrent laryngeal nerve function. Finally, the patient recovered completely from hoarseness during postoperative follow-up. Conclusion: A complete diagnosis and treatment process of recurrent laryngeal neurilemmoma was presented by the case. Particularly, it shows the application of recurrent laryngeal nerve monitoring in the operation helps to protect the continuity of the recurrent laryngeal nerve, which lays a anatomical bases for the follow-up nerve repair.
