  • Abstract
  • Look Inside

Gradually progressive leukocoria in the right eye since 3 months before led to the diagnosis of retinoblastoma in a 15-month-old girl. The tumor mass occupied the whole temporal half of the reti-na. The affected eye was enucicated and was subjected to histological and ultrastructural studies.

Histologically, the tumor mass consisted mainly of differentiated cells including, sporadically, typi-cal Flexner-Wintersteiner rosettes. Electron micro-scopically, so-called zonula adherens-like attach-ments were seen between tumor cells and normal retinal pigment epithelial cells at the apical surface of the latter.
