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...
متن کاملCentral Mandibular Nerve Sheath Myxoma
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...
متن کاملBenign epithelioid peripheral nerve sheath tumour resembling schwannoma.
Peripheral nerve sheath tumours (PNST) with epithelial appearing cells compromise a heterogeneous group of neoplasms that are rare and diagnostically challenging. Of these, malignant PNSTs with epithelioid features (epithelioid MPNST) are commonly described in literature. However benign epithelioid PNSTs are rare and till date about 38 cases have been described in the literature. We report a be...
متن کاملBenign nerve sheath myxoma: Atypical giant lesion in atypical location
32 ABSTRACT Benign nerve sheath myxoma (myxoid neurothekeoma) is a rare benign cutaneous neoplasm of nerve sheath origin. This tumor is commonly seen in the head and neck region and sometimes in the upper extremity. The presence of myxoid neurothekeoma on the lower limb is seldom and rarely reported. In this report we presented a new case of myxoid neurothekeoma in the lower limb of a 42-year-o...
متن کاملCellular schwannoma: a rare spinal benign nerve-sheath tumor with a pseudosarcomatous appearance: case report.
We report a case of cellular schwannoma, a rare benign nerve-sheath tumor in a 27 year-old woman. It was presented as a voluminous lesion in the paraspinal region that caused lumbar vertebral body destruction. These features, in association to the microscopic aspects of a hypercellular, pleomorphic neoplasm may lead to a false impression of a malignant tumor. Therefore, it is important to have ...
