1. Cholesteatoma and hydrocephalus associated to a third ventricle meningioma in a cat
RESUMO: Meningiomas são neoplasias que comumente envolvem o sistema nervoso central de gatos, enquanto colesteatomas são formações nodulares granulomatosas raramente descritas nessa espécie e que resultam de lesões crônicas em plexo coroide. O objetivo desse trabalho é descrever um caso de meningioma em terceiro ventrículo culminando com a formaç�

2. Espectro tumoral e alterações moleculares associadas à tumorigênese em portadores da mutação TP53 R337H / Tumor spectrum and molecular changes associated to tumorigenesis in carriers of TP53 R337H mutation
O gene supressor de tumor TP53 é um dos mais bem caracterizados genes cujo papel na etiologia é conhecido tanto em tumores hereditários como esporádicos. Mutações germinativas neste gene normalmente estão associadas à Síndrome de Li-Fraumeni, uma síndrome de predisposição ao câncer cujos portadores apresentam alto risco de desenvolvimento de uma

3. Rhabdoid choroid plexus carcinoma: a rare histological type
Primary central nervous system atypical teratoid/rhabdoid tumors mostly occur during early childhood and are almost invariably fatal. These tumors show similar histological and radiological features to primitive neuroectodermal tumor, meduloblastoma and choroid plexus carcinoma, but present different biological behaviors. We present the case of an 18 year-ol

4. Platelet-Derived Growth Factor Receptor Expression and Activation in Choroid Plexus Tumors
Choroid plexus tumors are intraventricular neoplasms predominantly affecting young children. In contrast to choroid plexus papillomas, choroid plexus carcinomas progress frequently, necessitating the development of adjuvant treatment concepts. Platelet derived growth factor (PDGF) signaling has been shown to support growth in a variety of tumors. The finding

5. Familial occurrence of tumours of the choroid plexus.
The case histories of two children of consanguineous parents with papillomas of the choroid plexus are presented. Although exogenic factors in the genesis of these neoplasms can not be excluded, autosomal recessive inheritance is proposed.

6. Immunohistochemical localization of apolipoprotein E in human glial neoplasms.
Immunocytochemical analyses revealed the presence and distribution of apolipoprotein E (apo E) in normal human brain tissue as well as in 77 human intracranial neoplasms. In normal brain tissues, the perikarya of astrocytes exhibited a strong positive reaction, whereas the Bergmann glia were stained to a moderate degree. However, no immunoreactivity was obse

7. Melanosis and associated tumors in transgenic mice.
Melanosis was found to various extents in a wide array of tissues of all 23 autopsied mice whose transgene consisted of the tyrosinase promoter fused to the simian virus 40 early-region oncogenic sequences. Pigmentation in a given animal was attributable to any or all of the following; an increase in numbers of some normally pigmented cells of neural crest o
