Squamous cell carcinoma (keratinzing)


Keratinizing SCC is much more common than non-keratinizing SCC, comprising 80-85% of all cases.  It shows papillary, exophytic and inverted growth patterns with keratinization.  Shown here is a moderately-differentiated sinonasal SCC (low mag: left; high mag: right).
