Study Notes

Vesicle: Small fluid-filled lesion, either single or grouped, less than 1cm in size containing serum, plasma, or blood.
Bulla: Larger version of a vesicle, characterized by being more than 1.0cm in size.
Pustule: Vesicle-like lesion containing pus.

Primary Lesions:
- Congenital lesions or those emerging directly due to pathologic, traumatic, or physical injury to tissue.
Secondary Lesions:
- Develop due to progressive, degenerative, or reparative changes arising from primary lesions.

Macule: Flat, circumscribed area varying in size, color, or shape; can be any color but remains flat.
Patch: A macule that is larger in size.
Plaque: Flat area with raised edges, typically thicker than a macule.

Papule: Elevated tissue, may be punctate or linear, does not exceed 1.0cm in size.
Nodule: Similar to a papule but larger and deeper, exceeding 1.0cm in size. Can be identified as a torus mandibularis in diagnosis.
Tumescence or Tumor: General term for swelling of any color, indicating an increase in tissue.

Erosion: Gradual loss of superficial tissue without extending beyond the topmost layer.
Ulcer: Loss of surface tissue due to necrotic inflammatory tissue sloughing, extending into the lamina propria.

Hyperplasia: Tissue increase in size due to a rise in the number of cells.
Hypertrophy: Tissue increases in size due to enlargement of the existing cells.
