An early lesion of atherosclerosis which may be found in persons of any age in large vessels.

Dentistry
A soft sticky substance on teeth composed of bacteria and saliva; an indurated soft mass of polysaccharides and bacteria—e.g., Lactobacillus acidophilus, Streptococcus mutans.
Dermatology
A flat, solid, elevated, ≥ 1.0-cm-diameter skin nodule formed either by extension or coalescence of papules of lichen amyloidosis, lichen simplex chronicus, lichen planus, or psoriasis; a “plaque” stage occurs in certain skin tumours (e.g., the second stage of Kaposi sarcoma), and evolving mycosis fungoides.

Molecular biology
A clear area on a lawn of bacterial cells caused by the lysis of infected cells by a phage.

plaque

a clear area in a ‘lawn’ of bacterial growth, in which the bacteria have undergone LYSIS due to BACTERIOPHAGE infection. The number of plaque-forming units in a given volume applied to the lawn can be used to calculate viral numbers in a suspension.
a layer that forms on the surface of a tooth, composed of bacteria in an organic matrix (see BIOFILM). As the layer thickens, anaerobic respiration of the bacteria produces acids which dissolve the tooth enamel.

Plaque

Patches of scar tissue that form where the layer of yelin covering the nerve fibers is destroyed by the multiple sclerosis disease process.Mentioned in: Angiography, Angioplasty, Atherosclerosis, Cholesterol Test, Coronary Artery Disease, Heart Attack, Ischemia, Multiple Sclerosis, Oral Hygiene, Peripheral Vascular Disease, Tooth Decay
