Schwannoma of the inferior turbinate: case report and review of literature

Abstract

Schwannomas of the sinonasal tract are rare entities that are amenable to local resection. We present a 69 year old woman with a schwannoma of the inferior turbinate that was successfully resected. Schwannomas arising from the inferior turbinate are very infrequent.

Schwannomas of the Sinonasal Tract and Anterior Skull Base: A Systematic Review of 94 Cases

“…Ninety-four ASB and sinonasal schwannoma cases were identified (Table 1 [for online version of article]). 1–71 These cases were published between 1974 and 2012. All cases reported age, sex, and location.…”

A Rare Case of Nasal Schwannoma of Middle Turbinate

“…A sinonasal schwannoma can be found at different sites, including the nasal septum, tip of the nose, turbinate, paranasal sinus and nasopharynx. [3][4][5] Ethmoidal sinus is most common site amongst sinuses. Nasal schwannomas are presumed to be arising from the sheath of the ophthalmic and maxillary branches of the trigeminal nerve and autonomic ganglia.…”

“…Hypocellular areas are called Antoni B, which contain oval to spindle cells arranged more haphazardly in a loose fibrous matrix. 4 Thickened hyalinized vessels are prominent in many cases. Tumors cells are diffusely immunopositive for S100 protein and collagen type IV with delicate pericellular reactivity reflecting basement membrane like deposition (Figure 4).…”

“…2 Cases with nasal schwannoma arising from nasal septum and inferior turbinate have been reported. 3,4 Nasal schwannoma has no age or sex predilection.…”

An Extensive Unilateral Nasal Mass: Septal Schwannoma—Case Report

“…Out of all schwannomas occuring in the body, 45% of them are from head and neck region. Out of those 45%, involvement of nose and pasanasal sinuses is only 4% [3,4]. Diagnosis of nasal schwannoma depends upon histological findings because it has no characteristic radiological features [5].…”
