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.

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 ...

Brain parenchyma schwannoma is a rare intracranial tumor, and especially rare in cerebellar hemisphere. In this report, a case of cerebellar schwannoma in a 52-year-old woman, was studied by computed tomography (CT), magnetic resonance image (MRI) and PET-CT. This tumor was totally removed by surgery. The histological diagnosis of schwannoma was confirmed by histological, HE and immunohistologi...

Schwannoma is well-known as a benign tumor originating from the Schwann cells, which produce insulating myelin sheath to cover peripheral nerves. It could occur in any nerve region, typically in the extremities, spinal cord and central nervous system (1). In the literature, only few cases of rectal schwannoma have been reported (2-8). The surgical approaches, including abdominoperineal resectio...

We present a 77-year woman with a size of 9.5x9x7cm giant ancient schwannoma located in the lower arm. Increased activity accumulation in the tumor was seen on the Tc-99m-methylene diphosphonate bone scintigraphy. After excision of the tumor, Pathologic diagnosis could be illustrated as an ancient schwannoma. Previous studies reported that Schwannoma could be demonstrated with increased Tc-99m-...
