comedo (KOM-i-doh) - n., a blocked and swollen skin pore.
The primary symptom of acne. The block is keratin shed from the skin mixed with oils and hardened, and the blockage can be open to the air, resulting in a blackhead, or closed lower down in the pore, making a whitehead. The name is interesting: it's from Latin comedÅ, glutton, because when you squeeze a blackhead the wormlike shape that comes out resembles a worm believed to feed on flesh, comedere, to eat up, from com-, here a intensifying prefix + edere, to eat.
