Neurilemoma of the larynx: A case study

Abstract

Neurilemoma of the larynx is not common. Thus far, 86 cases have been described in the literature. In this study, another case, occurring in a 67-year-old woman, is discussed. The potential danger of the lesion is emphasized. The most common nerve of origin is thought ot be the internal branch of the superior laryngeal nerve. Removal via a lateral pharyngotomy is advocated for larger tumors.

Subglottic nerve sheath tumor in a pediatric patient: Case report and literature review

“…In small, well-defined tumors, this approach appears to offer complete resection with little morbidity. 20,21 Others, citing potential for incomplete resection and airway compromise, advocate open techniques, including lateral thy-rotomy, lateral pharyngotomy, and laryngofissure. 5,6 These approaches offer direct visualization and greater likelihood of complete resetion.…”

“…Nanson 21 proposed that the internal branch of the superior laryngeal nerve is the source of laryngeal neurilemmomas. This is based upon the presence of a supraglottic lesion.…”

Laryngeal Schwannoma Excision by Lateral Pharyngotomy

“…Such a lesion coupled with impaired vocal cord mobility should draw attention towards a neurogenic tumor. 7 CT scan of the neck shows a well-defined, hypodense submucosal mass without signs of infiltrative or destructive growth with heterogeneous contrast enhancement. 5 On MRI scanning, the lesion is expected isointense to slightly hyperintense in T1-weighted images with strong, inhomogeneous enhancement of gadolinium, in T2 the lesion is hyperintense.…”

Schwannoma Mimicking Laryngocele

“…They are encapsulated and they grow eccentrically away from the nerve trunk. The internal branch of the superior laryngeal nerve is the most likely nerve of origin (6). The final diagnosis is based on histologically demonstrating characteristic spindle cells with typical nuclear palisading, Antoni A and B areas on the microscopic examination and positive immunohistochemistry for S100 protein.…”
