Fig. 1From: The prognostic role of single cell invasion and nuclear diameter in early oral tongue squamous cell carcinomaHematoxylin and eosin-stained section of early-stage oral tongue cancer (magnification ×200). Single cell invasion presented at the same time with large nuclei (arrows). Single cell invasion refers to detachment of single cancer cells from the main tumor mass, and large nuclei are greater in diameter than four nearby small lymphocytesBack to article page
