BACKGROUND Schwannoma is a tumor that develops on peripheral nerves or spinal roots. Although any part of the body can be affected, axillar and supraclavicular lesions are unusual for schwannoma. We report two cases of schwannoma arising in the brachial plexus, which were detected by 18F-fluorodeoxyglucose positron emission tomography and computed tomography (FDG-PET/CT). CASE 1 A 75-year-old...

Schwannomas are soft tissue sarcomas arising from neurilemma of Schwann cells in peripheral nerves, and is the most frequent type of benign tumor found in these nerves. We report a case of a Schwannoma of the ulnar nerve in the elbow joint, and along this report, give a review of the literature. A 46-year-old male patient was hospitalized with complaints of swelling and pain in the left elbow a...

Schwannoma is a benign neoplasm of the nerve sheath origin. It arises from the nerve sheath of large peripheral or cranial nerves and occurs at the level of the subcutaneous fat layer or deeper layer. Cutaneous schwannoma occurs more superficially and usually presents as a solitary dermal or subcutaneous nodule. We describe a case of cutaneous schwannoma that presented as an erythematous pedunc...

Microcystic/reticular schwannoma is a rare variant of schwannoma with a predilection for visceral locations including the gastrointestinal tract. Due to overlapping features with other tumours, unawareness of this tumour type may lead to diagnostic pitfalls. We here report a case of microcystic/reticular schwannoma arising in the mesentery of a 25-year-old female. The tumour was incidentally di...

the neurilemmoma is a benign neoplasm of schwann cell origin. one of the histopathologic subtypes of this tumor is ancient schwannoma which is characterized by degenerative alterations including cystic change, calcification, hemorrhage, and hyalinization. intraosseous schwannomas especially ancient ones are rare tumors. here we present a case of intraosseous ancient schwannoma in the lower jaw ...

Schwannomatosis is a term used to describe patients with multiple nonvestibular schwannomas with no other stigmata of neurofibromatosis type-2 (NF2). Neuroblastoma-like schwannoma is a rare subtype of schwannoma, with histological features resembling a neuroblastoma. This case is probabaly the second case of very uncommon neuroblastoma-like schwannoma, in a patient of schwannomatosis.

Background: Intraoral radiographies are the most frequent X-ray examinations in humans. According to International Commission on Radiation Protection (ICRP) recommendations, the selection of a diagnostic reference level (DRL) should be specific to a country or region. Critica l organs such as thyroid gland are exposed to X-rays in intraoral radiography and these exposures should be kept as low ...

Schwannoma is a benign tumor arising from Schwann cells that form the neural sheath. Primary schwannoma of the colon is rare and a few cases have been reported. We report a case of schwannoma of the colon and present the differential diagnosis that must be considered in the evaluation of colonic subepithelial lesions.

Multi-segment Facial Nerve Schwannoma (MFNS) is a very rare tumor, benign in nature and can arise anywhere along the course of facial nerve from its origin cerebello-pontine angle to extra cranial ramification parotid space head neck. It mimic like vestibular schwannoma other schwannoma. The most common clinical presentation palsy depending upon segment involved. We report case multi-segment ex...

Schwannoma is a tumor of soft tissue originating from Schwann cells that rarely appears in the retroperitoneum. Presentation depends on site disease leading to mostly pressure symptoms, sometimes with distal manifestations. Because its complex location, it has varied presentations and always diagnostic dilemma. We reported rare case retroperitoneal schwannoma having mild difficulty walking due ...
