    Study Notes

    Chromosomal Abnormalities

    • Genetic mutations can lead to various chromosomal abnormalities that affect cell function and development.

    Nutritional Imbalances

    • Nutritional status can significantly affect cellular health, including both deficiencies and excesses.

    Cellular Adaptation

    • Cells can adapt to stress through several processes, moving from a normal state towards injury.
    • Hyperplasia occurs when cells capable of DNA synthesis increase in number.

    Types of Hyperplasia

    • Physiologic Hyperplasia
      • Hormonal: Examples include breast development during puberty and uterine changes in pregnancy.
      • Compensatory: E.g., liver regeneration after resection or injury.

    Dysplasia

    • Characterized by disordered cellular development, primarily affecting epithelial tissues.
    • Involves cellular pleomorphism, with variations in cell size and shape, as well as nuclear irregularities.

    Benign Neoplasms

    • Chondroma: A benign tumor that develops in cartilage tissue.
    • Hemangioma: A benign tumor formed from blood vessel proliferation.
    • Lipoma: The most common benign fatty tumor, typically located just beneath the skin.

    Pathways of Tumor Spread

    • Lymphatic Spread: Tumor cells spread through the lymphatic system.
    • Hematogenous Spread: Tumor cells disseminate via the bloodstream.
    • Seeding of Body Cavities: Tumor cells can invade pleural, peritoneal cavities, and cerebral ventricles.
