Choroid plexus carcinoma, light micrograph. Choroid plexus tumours comprise less than 1% of all brain tumours. Almost 80% of cases occur in children making up 2% to 4% of pediatric brain tumours. The most common location is lateral ventricles. Given their location, the presenting symptoms and signs are related to hydrocephalus and increased intracranial pressure. Choroid plexus carcinomas are solid, infiltrative tumours frequently with foci of haemorrhage and necrosis. Choroid plexus carcinomas show papillary architecture in better differentiated foci (as shown in this image). Poorly-differentiated areas are generally solid and composed of highly atypical cells arranged in sheets. The papillary cores in this choroid plexus carcinoma are lined by anaplastic cells with irregular hyperchromatic nuclei. | |
