Abstract:
The cytopathologic features of choroid plexus papilloma observed in the ventricular fluid of a 9-month-old boy are reported and compared with other pediatric central nervous system neoplasms. The cytologic features of choroid plexus papilloma are similar to those of normal choroid plexus and may be difficult to distinguish from those of a well-differentiated papillary ependymoma. However, the cell clusters are distinct from those associated with choroid plexus carcinoma and primitive neuroectodermal tumors.
