    Notes: Abstract Malignant rhabdoid tumors (MRT) are characterized by a typical light microscopic morphology with uniformly round tumor cells, vacuolated cytoplasm with occasional round, hyaline intracytoplasmic, periodic acid-Schiff-positive inclusions, vesicular nuclei with prominent nucleoli and positive immunoreactivity for vimentin. The histogenesis of MRT is controversial. Five cases of primary central nervous system (CNS) rhabdoid tumors in children are presented. Immunohistochemical, light and electron microscopic features are compared with primary CNS malignant rhabdoid tumors reported in the literature. Expression of various neurofilaments in our cases of primary CNS rhabdoid tumors was prominent and we therefore favor a neural differentiation of extrarenal intracerebral rhabdoid tumors.

    Notes: Summary Giant axonal neuropathy (GAN) is a disease characterized by a slowly progressive neuropathy and signs of central involvement, manifested by visual impairment, corticospinal tract dysfunction, ataxia, and dementia. Pathological hallmarks of the disease include axonal swellings packed with neurofilaments in both peripheral and central nervous systems, and accumulations of intermediate filaments in Schwann cells, fibroblasts, melanocytes, endothelial, and Langerhans cells. Rosenthal fibers, sometimes appearing in masses and mimicking Alexander's disease, emerge as a conspicuous characteristic in longstanding GAN.
