Introduction: Presence of vestibular schwannoma and a simultaneous glomus jugulare tumor is an extremely rare event. There is only one case report regarding the incidence of a contralateral vestibular schwannoma, along with a glomus jugulare tumor. Herein, we present the second case with a contralateral tumor.   Case Report: A 69-year-old woman presented with a long hist...

Hybrid benign peripheral nerve sheath tumors are rare tumors exhibiting areas of more than one neural neoplasm such as schwannoma/neurofibroma, neurofibroma/perineurioma, or schwannoma/perineurioma. These tumors usually arise in the skin of the extremities and trunk, and less commonly affect extracutaneous sites. Here we report two cases of these tumors exhibiting hybrid features of schwannoma/...

Benign epithelioid schwannoma is a very rare variant of schwannoma, that can pose a diagnostic challenge. The reported cases were predominantly located in dermal/subcutaneous tissue. Although conventional schwannoma occurring in the posterior mediastinum was common, to our knowledge, no mediastinal benign epithelioid schwannoma was reported in English literature. Herein, we presented a case of ...

Schwannoma, also termed neurilemmoma, arises form Schwann cells, which cover the peripheral nerves. It commonly occurs in the peripheral nerve of the limbs or body, spinal cord, and the central nervous system. Occasionally, Schwannomas can occur elsewhere, including subcutaneous t issue, the re t roper i toneum, mediastinum, vulva, breast, larynx, and foot. There has been a relatively small num...

INTRODUCTION Gastrointestinal stromal tumor (GIST) is the commonest mesenchymal tumor of GI tract and 60-70% of it seen in the stomach, whereas Gastric schwannoma is a benign, slow growing and one of the rare neoplasms of stomach. Age distribution, clinical, radiological features and gross appearance of both tumors are similar. PRESENTATION OF CASE We report a rare case of gastric schwannoma ...

In their article, “Mass Screening for Retrocochlear Disorders: Low-Field (0.2-Tesla) versus High-Field (1.5-T) MR Imaging,” Dr Dubrulle and his associates ask whether low-field-strength open T1-weighted spinecho contrast-enhanced MR images of the cerebellopontine angle (CPA) and internal auditory canal (IAC) can be used to effectively diagnose lesions that cause sensorineural hearing loss (SNHL...

tongue base lesions have a diverse and extensive etiology. one of the benign tongue base lesions is schwannoma. schwannoma and neurofibroma are two tumors of the peripheral nerves originating in the nerve sheaths. schwannoma account for just over 1% of benign tumors which have been reported in the oral cavity and base of the tongue and with regard to its involved area in the oral cavity is very...
