adenocarcarcinoma
Microscopically, look at a region where you can see both malignant and
benign elements in the
same field. The difference
in gland and cellular morphology will be much more evident. The malignant glands show
"gland within gland" pattern as well as disorganized arborization and branching. The
usual cellular
features of malignancy are here in abundance: nuclear-cytoplasmic ratio, hyperchromasia, angulated nuclear margins etc.
