Oral nerve sheath myxoma: a rare and unusual intraoral neoplasm
We present a rare case of intraoral nerve sheath myxoma. Clinically, the neoplasm mimics many other oral mucosal pathosis, underscoring the importance of histopathology in ensuring accurate diagnosis of oral mucosal lesions. Reports of intraoral nerve sheath myxomas are essential to enhance our understanding of this rare intraoral entity.

Nerve sheath myxoma defined by Harkin and Reed is an uncommon benign neoplasm with nerve sheath like features. It has several cytological and histological differential diagnoses. One such lesion is neurothekeoma, which can be differentiated using immunohistochemistry. In most of the previous reports nerve sheath myxoma and neurothekeoma were considered synonymous and were often confused for one...
متن کاملIntraoral nerve sheath myxoma: case report and systematic review of the literature.
BACKGROUND Oral nerve sheath myxoma (NSM) is an uncommon benign neoplasm with Schwann-cell origin, which is frequently mistaken for neurothekeoma. We report a case of NSM on the buccal mucosa in a 42-year-old woman. This case is compared with previously reported cases and a systematic review is performed. METHODS AND RESULTS We conducted a case report and systematic review of oral cases consi...
متن کاملPalmar Nerve Sheath Myxoma: A Case Report.
Nerve sheath myxoma is a rare benign tumor of the peripheral nerves. It typically presents as a painless, firm, and slow growing nodule with a predilection for extremities mostly fingers and knees. Microscopically, it has characteristic multilobules of spindle cells in an abundant myxoid stroma. The cells are strongly positive for S-100 protein. However, this rare tumor is usually misdiagnosed ...
