The ancient schwannoma is a rare variant of a neurilemoma with a course typical of a slow-growing benign neoplasm. Histologically, it can be confused with a malignant mesenchymal tumor because of increased cellularity, nuclear pleomorphism, and hyperchromatism. Despite the degree of nuclear atypia, mitotic figures are absent. We describe the clinical and histopathologic features of an ancient s...

We report a patient with a schwannoma of the eighth cranial (vestibulocochlear) nerve who presented with isolated episodes of paroxysmal vertigo and positive Dix-Hallpike maneuver, and without the common features of hearing loss, disequilibrium and tinnitus. There are no previous reports of paroxysmal episodes of vertigo as the sole manifestation of schwannoma of the vestibulocochlear nerve. He...

Schwannomas are slow-growing nerve sheet neoplasms which are rarely found in the female genital system. In this article, we present a patient with Antony A congenital plexiform schwannoma of the clitoris. A 6-year-old girl was brought to our hospital with the history of a firm non-cystic clitoral mass from birth, which had been growing more rapidly during the previous year. The patient was sche...

Primary neurogenic tumors of trachea are extremely uncommon and account for only about 9% of all neoplasms of trachea. Tracheal schwannoma is among the rarest of them and there is no unanimity of opinion regarding its treatment. We report a 30 year-old woman with symptoms of airway obstruction due to primary tracheal schwannoma. She was suffering from cough and exertional dyspnea. She was admit...

Schwannomas are solitary benign tumours derived from peripheral nerve sheath that are difficult to diagnose using imaging only. Diagnoses are commonly confirmed with conventional surgical resection. Small proportion of cases are formed by cellular schwannoma usually seen at paravertebral, pelvic, retroperitoneal, or mediastinal location. This patient had a 3 x 2 cm hard mass at the dorsal side ...

Background: To report the first case of a renal schwannoma excised with robot-assisted laparoscopy. Case Presentation: A 43-year-old Caucasian female patient with vague abdominal symptoms was noted to have incidental right renal mass. Physical examination and laboratory tests were within normal limits. CT revealed a 4.6 cm heterogeneous enhancing right renal mass arising near the hilum. RENAL n...

We present a rare case of intramuscular schwannoma originating from the dorsal ramus nerve in a 62-year-old woman. The mass grew slowly, with pain developing upon touch five years prior. No neurological deficit was detected. The mass was observed in the erector spinae muscles in magnetic resonance imaging (MRI), and surgical excision was performed. The mass was well encapsulated with clear marg...

Background: Schwannoma is a benign tumor arises from Schwann cells of the peripheral nerves. Tongue base schwannomas are very rare and have been sporadically reported; it usually missed when evaluating tongue mass. This work aimed to report new case schwannoma review literature about this tumor. Case presentation: A male patient 40 years old presented with slowly enlarging mass at base. Clinica...

Acute hemorrhagic presentation of spinal schwannoma is an event rarely seen. We had ever reported a 63-yearold male presenting with acute spinal cord compression caused by a long segment of intradural extramedullary schwannoma with hemorrhage and atypical enhancement pattern. The magnetic resonance image findings included a long segmental irregular contour, intermediate signal intensity on T1-w...

Background: Schwannoma is a benign encapsulated nerve sheath tumour that arises from the Schwann cells along course of and can affect third to 12th cranial nerves, peripheral autonomic nerves. was first described by Verocay in 1908. rarely affects brachial plexus, accounting for 5% all cases schwannoma. Case: 38year old female patient presented with left axillary mass noticed since 1 year. The ...
