Abstract

The ultrastructure of two retinoblastomas includes cytologic features which are characteristic of neoplasia. Unusual degenerative changes were observed in both tumors. Rosettes were present in one case, and the cells which formed them showed some characteristics of ependyma of the primitive neural tube, and also of developing vision receptor cells. Structures resembling pericentriolar bodies were associated with basal bodies of cilia in rosettes.
