What Are the Histological Differences Between Acute and Chronic Injuries?
Acute injuries often exhibit:
- Edema: Fluid accumulation in the interstitial spaces. - Hemorrhage: Blood leakage due to ruptured vessels. - Cellular Infiltration: Predominantly neutrophils in the initial phase.
Chronic injuries, on the other hand, show:
- Chronic Inflammation: Presence of lymphocytes, macrophages, and plasma cells. - Granulation Tissue: Newly formed connective tissue with proliferating capillaries. - Fibrotic Changes: Increased collagen deposition and scar tissue formation.
