The neoplasm may originate from a peripheral or sympathetic nerve, or from various cranial Intraosseous schwannoma (neurilemmoma) is a rare neoplasm, with fewer than 60 histologically doc- umented cases having been reported in the English- language literature.1 In one large series, schwan- nomas accounted for less than 0.2 per cent of primary bone tumors,2 which are themseh, es relatively rare. Histologic examination of the well-circumscribed neurilemmoma shows degenerative changes and a variable presentation of compact spindles, referred to as "Antoni A" bodies and microcystic areas with a high concentration of macrophages and collagen fibers, designated as "Antoni B" bodies. Also called neurilemmoma, benign peripheral nerve sheath tumor Benign (rarely malignant if associated with neurofibromatosis) neoplasm originating from Schwann cells of cranial nerve VIII, superior or vestibular branch 10% of intracranial neoplasms, 90% of tumors at cerebellopontine angle The most common type is the neurilemmoma, which may cause diagnostic problems because of hypercellularity and the fact that - in contrast to its more common counterpart in the soft tissue - it is often unencapsulated. We encountered one case of neurilemmoma. Histology revealed uniform spindle cells arranged in loose stroma.

To evaluate the clinical pathology and postoperative outcomes of patients with neurilemmoma in the upper extremity who underwent tumour enucleation, and the correlation factors for neurological The histologic features of intraosseous neurilemmoma are similar to those of soft tissue neurilemmoma. Microscopically, neurilemmoma has identifiable Antoni A and Antoni B regions. The diffuse immunoreactivity for S-100 protein is indicative of a Schwann cell origin, and helps distinguish this tumor from other benign spindle cell lesions of similar histology. 1985-03-01 in 6 patients were of Antoni A type histology and in Journal of Orthopaedic Surgery 2004;12(2):222–225 Vol. 12 No. 2, December 2004 Neurilemmoma in the upper extremity 223 Samter TG, Velios F, Shafer WG.

The cell of origin for a neurilemmoma is the Schwann cell, which is derived from neurilemmoma: ( shwah-nō'mă ) A benign, encapsulated neoplasm in which the fundamental component is structurally identical to a syncytium of Schwann cells; the neoplastic cells proliferate within the endoneurium, and the perineurium forms the capsule. The neoplasm may originate from a peripheral or sympathetic nerve, or from various cranial The most common type is the neurilemmoma, which may cause diagnostic problems because of hypercellularity and the fact that - in contrast to its more common counterpart in the soft tissue - it is often unencapsulated.
