Rationale: Schwannomas are solitary neurogenic tumors that arise from cells of the neural sheath. Ancient schwannoma is a relatively rare variant of schwannoma, characterized by increased cellularity and atypia. These cellular changes could be confusing and make the accurate pathologic diagnosis difficult. Patient concerns and diagnoses: A 36-year-old man presented with painless swelling in lef...

Summary Background Schwannoma is a benign tumor arising from Schwann cells of the peripheral nerves. It often asymptomatic and can develop in retroperitoneum, mediastinum, head neck region, upper lower extremities. abdominal wall extremely rare, but differential diagnosis with malignant neoplasms important to reduce risk undertreatment. Methods A narrative review schwannoma was performed using ...

Abstract Background Schwannoma, also known as perineural fibroblastoma, neuroma, or neurilemmoma, is a slow growing benign tumor that exceptionally raises in oral cavity. It mainly affects the second and third decade can be life-threatening if it becomes large. Developing youth unusual. Case presentation A 16-year-old teenager presenting with relatively rapidly tongue base which radiologic inve...

Intramedullary schwannoma is often misdiagnosed as other types of malignant tumour prior to surgery due to its atypical imaging appearance and low incidence. In the present study, a case of small intramedullary schwannoma was analysed using clinical and imaging data. Data concerning the surgery and follow-up process of this case were collected. Instead of performing the traditional surgical pro...

Ancient schwannoma is a rare variant of benign peripheral nerve sheath tumor, often morphologically mimicking malignancy. Retroperitoneum is an uncommon location. We describe one case of giant retroperitoneal ancient schwannoma. Literature concerning this variant is also reviewed. A 65 year old male presented with altered bowel habits. Imaging findings revealed a large heterogeneous mass in the...

Schwannoma in the abdomen is an uncommon neoplasm that occurs most frequently in the cranial and peripheral nerves; it is extremely rare in the great omentum and only 6 cases of schwannoma of the great omentum have been observed previously. We report the case of a schwannoma found in the great omentum of a 55-year-old man who was treated with laparoscopic surgery. Though it was difficult to dia...

Schwannoma originating from the cervical vagus nerve is an extremely rare neoplasm. Vagal nerve schwannoma usually occurs between the third and fifth decades of life, it does not show sex predilection both sexes being equally affected and it most often presents as a painless, slow-growing, lateral neck mass. The treatment of choice is complete surgical excision with preservation of the neural p...

Primary malignant schwannoma of the small and large intestine is an extremely rare disease. Therefore, we are going to report an aggressive multifocal malignant intestinal schwannoma in a 66-year old female patient, that was primarily diagnosed as the gynecological tumor that, even after the surgical treatment, had a very quickly recurrence. Small intestine tumors may show images similar to an ...
