SWI/SNF deficient central nervous system neoplasms

Seminars in Diagnostic Pathology, 2021
The SWItch/Sucrose Non-Fermentable (SWI/SNF) complexes are ubiquitous ATP dependent chromatin remodeling complexes that provide epigenetic regulation of gene expressions across the genome. Different combination of SWI/SNF subunits allow tissue specific regulation of critical cellular processes.

Germinal Neoplasms of the Central Nervous System

Archives of Surgery, 1966
GERMINAL neoplasms of the central nervous system differ from the epidermoid-dermoid group of tumors within the central nervous system not only in respect to their location, but also in their genesis. The former are most often found in the region of the pineal gland. The pineal gland is generally involved or destroyed by the neoplasm, and on this basis,

Newly Defined Central Nervous System Neoplasms

Pathology Patterns Reviews, 2005
In recent years, numerous new entities or variants of recognized central nervous system tumors have been described in the literature, and the morphologic spectrum of these neoplasms is delineated incompletely. The accurate diagnosis and classification of these lesions is important to ensure that patients receive adequate therapy and prognostic ...

Infectious lesions mimicking central nervous system neoplasms

Seminars in Diagnostic Pathology, 2010
Infections of the central nervous system (CNS) presenting as space-occupying lesions are not uncommon, particularly in developing countries. Most often, infective organisms gain entry into the CNS through the hematogenous route, seed the parenchyma, and cause tissue destruction.

Metastases of central nervous system neoplasms

Journal of Neurosurgery, 1988
✓ Tumor-to-tumor metastasis is a rare occurrence. Fewer than 100 cases have been reported, many being metastases from carcinomas to benign intracranial neoplasms, most often meningiomas. A case is presented of carcinoma metastatic to a glioma. The patient, who presented for evaluation of bifrontal headache, was found on computerized tomography to have ...

AGING AND PRIMARY CENTRAL NERVOUS SYSTEM NEOPLASMS

Neurologic Clinics, 1998
The number of primary brain tumors in the aging population has increased over the past few decades. Although overall survival rates for many patients with primary central nervous system neoplasms have not changed drastically, patients with particular tumor types are benefitting from new treatments.

Central Nervous System Neoplasms

1993
A. Local effects of tumors 1. Infiltration, invasion, and destruction of normal central nervous system tissues by tumor produces focal neurological signs 2. Mass of tumor produces direct pressure on neural structures causing degeneration (although brain and spinal cord can adjust remarkably to gradually increasing pressure)

Primary melanocytic neoplasms of the central nervous system

Journal of Clinical Neuroscience, 2010
Primary melanocytic neoplasms of the central nervous system (CNS) are rare lesions arising from melanocytes of the leptomeninges. They include diffuse leptomeningeal melanocytosis or melanomatosis, melanocytoma and primary malignant melanoma. We have reviewed the English literature regarding these lesions, which consists of case reports and a small ...

Primary Melanocytic Neoplasms of the Central Nervous System

The American Journal of Surgical Pathology, 1999
Primary melanocytic neoplasms of the central nervous system (CNS) consist of a spectrum ranging from well-differentiated melanocytoma to its overtly malignant counterpart, melanoma. Diagnostically difficult intermediate lesions lie between these extremes.

Immunolocalization of cathepsin D in the human central nervous system and central nervous system neoplasms

Neuropathology and Applied Neurobiology, 1990
The cellular distribution of the lysosomal proteinase cathepsin D was studied in a series of 76 neoplasms and 18 non‐neoplastic tissues from the human central nervous system, using a well‐characterized polyclonal antibody in a peroxidase‐antiper‐oxidase technique. In the normal and developing brain, cathepsin D is confined to neurons and choroid plexus
