Antoni A area of schwannoma with Verocay bodies (one annotated by circle) Verocay bodies were first described by Uruguayan neuro-pathologist José Juan Verocay in 1910. It is a required histopathological finding for diagnosing schwannomas (tumors of Schwann cells).
A schwannoma (or neurilemmoma) is a usually benign nerve sheath tumor composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral nerves. Schwannomas are homogeneous tumors, consisting only of Schwann cells.
Schwannomatosis is an extremely rare genetic disorder closely related to the more-common disorder neurofibromatosis (NF). Originally described in Japanese patients, [1] it consists of multiple cutaneous schwannomas, central nervous system tumors, and other neurological complications, excluding hallmark signs of NF.
Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition that may be inherited or may arise spontaneously, and causes benign tumors of the brain, spinal cord, and peripheral nerves.
The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80%), followed by meningioma (10%). The cranial nerves affected are (from most common to least common) : VIII (cochlear component), VIII (vestibular component), V Acoustic neuroma/vestibular schwannoma
A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction.
Nebrazkha, a Spanish-speaking mother on TikTok, thought her son was “too ugly” as a newborn and demanded a DNA test to make sure he was hers. Others, however, didn’t think the video was a ...
The systemic and ocular prognosis for intraocular schwannoma is positive. While a patient may lose an eye, they are unlikely to encounter metastasized growth or life-threatening malignant change. Although follow-up data has shown the potential need for re-excision and side-effects, these issues are minor and the general outcome for patients is ...
