Definition

   • Abnormal development or growth of cells, tissues, or organs: A condition in which cells or tissues develop or grow in an abnormal way, often in terms of their size, shape, or organization. This can occur in various parts of the body and may be a precursor to cancer.

Advanced Usage

  • The pathologist's report noted mild dysplasia.
• Specific Types: Often modified by the tissue or location affected (e.g., fibrous dysplasia, skeletal dysplasia).
  • Fibrous dysplasia affects the bone, replacing normal bone with fibrous tissue.

Variants and Related Words

• Malformation: An abnormal shape or structure, often present from birth.

Antonyms

Notes

• Grading: Dysplasia is often graded (e.g., mild, moderate, severe) based on the extent of cellular abnormality.
