Nasal Schwannoma—A Case Report

Abstract

According to the literature, half of the schwannoma cases occur in the head and neck areas and only less than 4% occur in the sinonasal tract. In this case, a 50-year-old male patient, Mr. Jeyapal with a-year-long progressive left side nasal obstruction and purulent rhinorrhea, is presented [1]. The CT reveals a mass filling the left nasal cavity. During surgical intervention, the mass is found to originate from the medial side of the septum anteriorly and inferiorly. The pathological examination reveals capsulated tumor with palisading cellular arrangement and high cellular density [2]. The pathological findings and nervous origin of the tumor are discussed after an extensive review of the literature.

Two cases of neurilemmoma in the nasal vestibule

“…Neurilemmoma grows gradually with no accompanying subjective symptoms at the early phase; however, with tumor growth, pain appears due to pressure in the originating nerves. [ 8 ] Tumors in the nasal cavity are generally associated with the most common symptom of nasal congestion around the lesion; other symptoms, such as pain, headache, or anosmia, may manifest with tumor growth. [ 9 ] Based on the analysis of the clinical presentation of neurilemmoma in the nasal vestibule according to the Korean literature, most patients reported mild nasal congestion or presented no symptoms, except a few cases with pain or nasal bleeding (Table 1 ).…”

“…However, neurilemmoma in the nasal septum is frequently associated with unilateral nasal bleeding, severe nasal congestion, and headaches. [ 6 , 8 , 9 ] The severity of symptoms varies depending on the location of the tumor; for example, a tumor in the nasal vestibule can be easily identified by the patients in their early phase, and the disease may be diagnosed before symptom appearance due to the growing tumor.…”

“…However, neurilemmoma in the nasal septum is frequently associated with unilateral nasal bleeding, severe nasal congestion, and headaches. [6,8,9] The severity of symptoms varies depending on the location of the tumor; for example, a tumor in the nasal vestibule can be easily identified by the patients in their early phase, and the disease may be diagnosed before symptom appearance due to the growing tumor. Neurilemmoma generally appears as contrast-enhanced homogenous soft tissue shadow on the CT image; however, in necrotic cases or cystic degeneration, heterogeneous shadow or calcification may be observed.…”
