Inferior Turbinate Schwannoma: Report of a Case

Schwannomas are rare slow-growing benign tumors arising from Schwann cells lining the nerve sheaths. Head and neck schwannomas account for about one-third of all cases, and only 4% of them arise from the sinonasal tract. Its diagnosis is based on histology and immunohistochemistry. Complete surgical excision is the most recommended treatment option, and endoscopic surgery has been widely performed in recent years. In this study, we presented a case of a 55-year-old female with schwannoma arising from the lateral wall of the nasal cavity, causing epistaxis and rhinorrhea. The patient underwent endoscopic excision with prompt resolution of symptoms. The reported cases of nasal cavity schwannoma were reviewed and summarized for educational purposes.

Neurilemmoma Presenting as a Midline Nasal Mass in a Pediatric Patient

We report a case of a neurilemmoma presenting as a midline nasal mass in a 13-year-old girl. To the best of our knowledge, this is the first report of a nasal neurilemmoma in a pediatric patient. Although this neoplasm is benign in nature, surgical resection is warranted to prevent recurrence, and it is the sole means of treatment. The overall prognosis is excellent, as was the case for our patient. We discuss the diagnosis and management of neurilemmomas and urge physicians not to exclude nasal neurilemmoma from the differential diagnosis in a pediatric patient who presents with a nasal mass.

Schwannomas of the nasal cavity and paranasal sinuses are quite rare, with 4% occurring in this location. Most of them are benign and do not recur when totally removed by surgery. It is very important to distinguish between schwannoma and primary benign neurofibroma. Neurofibromas are lesions having the possibility for malignant transformation and recurrence. A case of schwannoma in the nasal cavity is reported, and the diagnostic and therapeutic procedures, as well as recommendations from the literature, are described. The histological and immunohistochemical features are discussed in detail to draw a distinction between schwannoma and neurofibroma. In cases of intranasal and paranasal lesions, the existence of a schwannoma must be considered. Differentiating between schwannoma and neurofibroma is important for estimating the risk of malignant transformation and recurrence.
