1. Avaliação do Fator Induzido Pela Hipoxia 1-Alfa no Retinoblastoma
Introdução: o Retinoblastoma é o tumor intra-ocular maligno mais comum na infância. Pacientes com tumores avançados, em geral, respondem mal ao tratamento. Hipóxia é um fenômeno comum aos tumores avançados e está relacionada à resistência à quimio e radioterapia convencional. As células e os tecidos tumorais adaptam-se ao microambiente hipóxic

2. Melanotic mucin-producing neuroepithelial neoplasm of mesencephalon with consideration of similar tumours in different locations.
A six month old boy had a mesencephalic melanotic neoplasm of the neuro-epithelial derivatives which produced mucin. Location in the mesencephalon and production of the mucin have not been described previously for this kind of intracranial tumour. The various cellular elements within the growth are in accord with diverse differentiations of the neuroepitheli

3. Neuroblastoma arising in a mature cystic teratoma of the ovary
A case is described of a neuroblastoma which appeared to arise in a mature cystic teratoma of the ovary. The literature concerning neural tumours of the ovary is briefly reviewed and the grounds for believing that the development of such neoplasms is an indication of the presence of immature neuroepithelial components in a teratoma, rather than a result of m

4. Role of stereotactic biopsy in multifocal brain lesions: considerations on 100 consecutive cases.
One hundred patients affected by multifocal brain lesions were investigated by serial stereotactic biopsy. Systemic diseases and primary neoplasms elsewhere were previously ruled out. The histological diagnosis obtained in this series comprises malignant gliomas in 37% of patients; primary non-Hodgkin's brain lymphoma in 15%; metastatic brain tumours in 15%
