Abstract:

Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement of this tumor is extremely rare. Here, we present an unusual case of nerve sheath myxoma in the mandible of a 22-year old female patient. This case appears to be the first myxomatous variant which is centrally located in the mandible.

Nerve sheath myxoma of the tongue.

Nerve sheath myxoma (NSM) of the oral mucosa is a slow-growing, benign, often asymptomatic submucosal mass. We report on a case of classical NSM of the tongue, with diagnostic and therapeutic approach to the case. Many NSM arise within the endoneurium of a peripheral nerve. It is a rare condition with no apparent differences between sexes in its prevalence. It can occur at any age.

Palmar 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 ...

Nerve sheath myxoma (neurothekeoma)--a case report.

A case of nerve sheath myxoma also called as neurothekeoma in a 33-year-old woman is described. The lesion appeared as a painful, elevated nodule on the scalp for several months, without an appreciable increase in size. Microscopically, it showed typical histologic characteristics of nerve sheath myxoma, and tumor cells revealed strong, positive reaction for S-100 protein and negativity for epi...

Nerve sheath myxoma: an immunohistochemical study of a case.

An 18-year-old Japanese male presented with a normal-skin-colored, dome-shaped, slightly tender tumor on his left palm. Histopathologically, the tumor consisted of distinct lobules, which were separated by fibrous connective tissue. Each lobule was composed of spindle or round cells within a myxoid matrix, pathognomonic of nerve sheath myxoma. The mucinous material was positively stained by Alc...

Nerve sheath myxoma with bidirectional schwannomatous and perineural differentiation.

A case of nerve sheath myxoma occurring in occipital region in 70-yr-old woman is presented. The tumor showed typical lobular and myxoid morphology. Immunohistochemically, it showed unusual coexpression of Schwann cell markers S100 protein and GFAP with perineural cell markers EMA and claudin-1. CD34+ fibroblast-like cells were scarce, and nerve axons were not found in the tumor. Clinical patho...

Nerve sheath myxoma: report of a rare case.

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...
