Report on Feulgen-cytophotometric DNA studies of 8 choroid plexus papillomas. 7 tumours reveal distinct diploid stemlines in their karyogram. One tumour with oncocytic transformation exhibits a stemline in the triploid stage. These findings reflect the DNA pattern of a benign euploid neoplasm of the there investigated tumours.
