Abstract
Choroid plexus tumors (CPTs) are relatively uncommon tumors of the central nervous system, constituting approximately 5% of all pediatric brain tumors. Although squash cytology of CPT has been described in literature, shedding of tumor cells into cerebrospinal fluid (CSF) has rarely been described. We report two such cases of atypical choroid plexus papilloma in a 5-month-old male child and a 12-year-old female child, where characteristic cytomorphology of CPT was noted in the CSF.
