American Journal of Surgical Pathology, 1986
Choroid plexus neoplasms account for less than 1% of all intracranial tumors, with papillomas (CPPs) more frequent than carcinomas (CPCs). Immunocytochemical characterization of these neoplasms has been limited. Glial fibrillary acidic protein (GFAP), S100 protein, and keratin have been variably demonstrated by others.

THE NEURORADIOLOGY OF CHILDHOOD CHOROID PLEXUS NEOPLASMS
American Journal of Roentgenology, 1973The features of 14 cases of choroid plexus neoplasms from the Hospital for Sick Children, Toronto, are presented, and similar available data from 130 previously reported cases in children are tabulated.In any neuroradiologic practice, choroid plexus papillomas and carcinomas are rarely encountered.

Intraventricular neoplasms derived from choroid plexus epithelium including choroid plexus papilloma (WHO grade I), atypical choroid plexus papilloma (WHO grade II), and choroid plexus carcinoma (WHO grade III). The vast majority are sporadic, though rarely arise in association with hereditary cancer predisposition syndromes, including the Li Fraumeni ...

Clinicopathologic correlations in epithelial choroid plexus neoplasms: a study of 52 cases
Acta Neuropathologica, 1990Sixty-seven tumor specimens of epithelial choroid plexus neoplasms obtained by 60 biopsies and 7 autopsies from 52 patients were investigated. Diagnoses of the first operations were choroid plexus papilloma (PP; 32 cases), choroid plexus papilloma with histological atypies (atypical PP; 6 cases), and choroid plexus carcinoma (PC; 14 cases ...

A Critical Survey of Neoplasms of the Choroid
American Journal of Ophthalmology, 1925Reviewing recent work on the origin of melanin it is concluded that the chromatophores of the choroid and skin cannot produce pigment but are only phagocytic cells that ingest the melanin. A case is reported of buphthalmos for which the eye was removed, and studied microscopically.

Pediatric choroid plexus neoplasms
International Journal of Radiation Oncology*Biology*Physics, 1998Choroid plexus tumors (CPT) are rare childhood neoplasms. The relatively small number of reported cases and the controversies surrounding the clinical and pathological classification of these tumors have made it difficult to define a standard of care for these patients. Our intention is to contribute to the body of knowledge of these tumors and further

Ultrasonic diagnosis of a choroid plexus neoplasm in a child
The British Journal of Radiology, 1984Choroid plexus neoplasms arise from the epithelial cells of the choroid plexus of the brain and can occur wherever choroid plexus is found within the cranial cavity. Although relatively uncommon, these tumours are usually benign and are often accessible to surgical removal. It is therefore of paramount importance that their presence be recognised early

The Role of Radiotherapy in the Management of Choroid Plexus Neoplasms
Tumori Journal, 1989Choroid plexus papillomas are very rarely reported neoplasms in both the surgical and radiological literature. The authors present their series of 7 papillomas and 1 carcinoma. They review the recent and former literature with the aim of demonstrating the role and usefulness of radiotherapy.

NEOPLASM OF THE CHOROID PLEXUS
American Journal of Diseases of Children, 1934Neoplasms of the brain in infancy undoubtedly occur with greater frequency than reports of their discovery would suggest. Because of the readiness with which their symptomatology may be confused with that of gastro-intestinal dysfunction, particularly projectile vomiting, uncomplicated by a lesion of the nervous system, recognition of the presence of ...
