BACKGROUND Malignant peripheral nerve sheath tumors are rare tumor entities that originate from peripheral nerve sheaths and have an unfavorable prognosis. Metastatic spread to the cerebral parenchyma is absolutely rare. This case report describes the clinical course in a 60-year-old man whose tumor came to medical attention because of a seizure. CASE PRESENTATION Magnetic resonance imaging d...

Even though the diagnosis of schwannoma is usually straightforward in lesions with classic features, tumors with predominantly epithelioid morphology or marked myxoid change may present a diagnostic challenge. There are relatively few reported cases of epithelioid schwannoma entirely lacking classic morphology, and these have occurred in subcutaneous tissues, mucosal surfaces, or as gastrointes...

Introduction: Malignant Peripheral Nerve Sheath Tumour (MPNST) is a malignant tumour arising from peripheral nerve or showing sheath differentiation, with the exception of tumours originating epineurium vasculature. Most these arise on trunk, extremities, head and neck regions. MPNST scalp very rare. Case Report: We, report case 71-year-old woman lesion in over occipital region FNAC features MP...

A 40-year-old man presented with complaints of left-sided lower back discomfort for 2 to 3 months. There was no other significant history. Physical examination was unremarkable except for a palpable mass in the left flank. Ultrasonography showed a hypoechoic mass. Biphasic contrast-enhanced computerized tomogram revealed a large, heterogenous, infiltrating, necrotic mass lesion arising from the...

Samples of morbid bovine tissues obtained from slaughterhouse were submitted to histopathological examination. Neoplastic growth within the peripheral nerves was observed microscopically, with the presence of Antoni A and Antoni B patterns, and sporadically Verocay bodies. Additionally, immunohistochemical examination of the sections revealed positive reaction to vimentine, neuron specific enol...

introduction: repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. the aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the scia...

Schwannomas are well capsulated, benign, and slowly growing tumors which originate from Schwann cells of peripheral nerve sheath. The incidence of schwannomanas in the axillary region is not common. This rarity causes misdiagnosis at the radiological evaluation. In this case we present the imaging and histopathological findings of a cystic schwannoma located in the axillary fossa of a 47-year-o...
