Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...

Background: Promyelocytic leukemia protein (PML) is a tumor suppressor protein that is involved in myeloid cell differentiation in response to retinoic acid (RA). In addition, RA acts as a natural morphogen in neural development. Objectives: This study aimed to examine PML gene expression in different stages of in vitro neural differentiation of NT2 cells, and to investigate the possible role o...

Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement...

Typically, the diagnosis of a tumor is done through surgical sampling, which is more precise with existing methods. The difference is that this is an aggressive, time consuming and expensive way. In the statistical method, due to the complexity of the brain tissues and the similarity between the cancerous cells and the natural tissues, even a radiologist or an expert physician may also be in er...

Brain Tumor detection using Convolutional Neural Network (CNN) is used to discover and classify the types of Tumor. Over a amount years, many researchers are researched planned ways throughout this area. We’ve proposed technique that’s capable detecting classifying different tumor. For tumor we have MRI because images gives complete structure human brain, without any operation it scans brain he...

paragangliomas are neoplasms of neural crest origin. in the head and neck, they uncommonly involve the larynx. the distinction between paragangliomas and other neuroendocrine tumors can be difficult. precise diagnosis is important in order to optimize patient treatment. diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. here we report a 77-year-old woman wi...
