Neurilemmoma histology

Neurilemmoma also known as schwannoma is benign nerve sheath tumor rarely occurring in the oral cavity. Only 1% of all extracranial schwannomas show that intraoral occurrence with tongue is the commonest site and retromolar region is the least common site. It presents as encapsulated, slow growing, solitary, smooth-surfaced, usually asymptomatic tumor. We report a case of 70-year-old male Histology.

Syn: Neurilemmoma.

A schwannoma is a tumor (usually benign) of the Schwann cells - the glial cells that myelinate the axons of neurons that run within peripheral nerves. The tumor can form a small bump within a nerve and can grow slowly making it difficult to remove. If doubt persists and a biopsy is needed or symptoms dictate excision, histology provides further description. The tumor is unilocular and surrounded by a vascularized capsule composed of epineurium. Neurilemmomas contain benign spindle cells (Antoni A areas) and connective tissue (Antoni B areas) with no mitotic figures, and may contain calcification or hemorrhage areas or degenerative cysts.

Neurilemmomas contain benign spindle cells (Antoni A areas) and connective tissue (Antoni B areas) with no mitotic figures, and may contain calcification or hemorrhage areas or degenerative cysts. Schwannomas are homogeneous tumors, consisting only of Schwann cells. The tumor cells always stay on the outside of the nerve, but the tumor itself may either push the nerve aside and/or up against a bony structure (thereby possibly causing damage). Schwannomas are relatively slow-growing. For reasons not yet understood, schwannomas are mostly Of the 20 patients who underwent tumour enucleation for neurilemmoma in the upper extremity, 19 had a single nerve affected and one had multiple lesions involving two nerves.

Although non-malignant, neurilemmomas of such nerves as the acoustic nerve can be dangerous. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 Neurilemmomas (neurilemomas) are benign, encapsulated tumors of the nerve sheath. Their cells of origin are thought to be Schwann cells derived from the neural crest (see the image below) [ 1] ; Soft tissue - Schwannoma.

The neurilemmoma, also called a schwannoma or neurinoma, is a benign neoplasm originating from the peripheral neural sheath. Although the head and neck region is one of the most common sites for benign nerve-sheath tumors, intraoral lesions are unusual, particularly in the intraosseous region of the jaw. 27 Jun 2020 Pathology of Schwannoma · Nuclear palisading is common in the cellular areas.
