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...

Plexiform schwannoma is an infrequent variant of schwannoma characterized grossly and microscopically by multi-nodular growth. Although plexiform schwannoma has such growth patterns, it is a benign tumor as well as a conventional schwannoma. It rarely infiltrates adjacent organs or arises from the organ itself. In this report, we describe a case in which plexiform schwannoma involved the trache...

Neurilemmomas are benign tumors of peripheral nerve sheath Schwann cells. One of the variants of neurilemmoma is the ancient type of neurilemmoma characterized by degenerative features such as cystic degeneration, calcification, hemorrhage and hyalinization which could be easily misdiagnosed. Their occurrence in oral cavity is extremely rare and intraosseous type occurring in maxilla is exceedi...

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 ...

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...

The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma. About 19 months after the operation, a follow-up MRI showed no evidence of tumor...

acoustic neuromas (an) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(vs) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. in many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by mri. in the majority of cases the tumor is s...

Background: Tracheobronchial schwannomas are extremely rare tumors of neurogenic origin. Treatment includes surgery and interventional bronchoscopic therapy. Studies that have described therapy for tracheobronchial schwannoma been reported in the published literature, but most them individual case reports, which long-term efficacy recurrence poorly understood. This study aimed to explore feasib...
