Although rare (lessthan1% of all intracranial tumors), choroid plexus tumors (CPTs) are relatively common neoplasms of infancy, with papillomas more frequent than carcinomas. Because surgical resection is the optimal treatment, the pathologist needs to consider the diagnosis of CPTs (any grade) during intraoperative consultation. Highly cellular preparations of epithelial appearance with large papillae, small cell clusters, and single cells are characteristic smear features of these tumors.
