Study Notes

Oral Soft Tissue Lesions

  • 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.

Classification of Lesions

  • 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.

Primary Lesion Types

  • 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.

Elevated Lesions

  • 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.

Secondary Lesion Types

  • 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 vs. Hypertrophy

  • 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.
