  • Abstract
  • Look Inside

Squamous cell carcinoma of the eyelid was studied by electron microscope.

The nuclei of tumor cells revealed enlarge-ment, increased nuclear membrane infoldings and enlargement of the nucleoli.

In the cytoplasm, mitochondria decreased in number, were enlarged and swollen. Glycogen was few or absent. The endoplasmic reticulum showed prominent vacuolation, loss of tonofila-ments and increase of free-ribosomes. The des-mosomes either decreased in number or were lost. There was an absence of the usual tono-fibrils at the desmosomes. The basement mem-brane was frequently present in imperfect form. Where the basement membrane was absent, small protrusion of carcinoma cell cytoplasm was seen in the adjacent stroma.
