A patient has a draining sinus tract from tooth #3. What cells predominate in the exudate?
Show answer and explanation
Correct answer: C. Neutrophils
- A. Macrophages are key in chronic inflammation and phagocytosis; they are present but not the primary cell in acute purulent exudate.
- B. Plasma cells are seen in chronic inflammation and antibody production; not the primary cells in purulent drainage.
- C. Neutrophils (PMNs) are the hallmark cells of acute purulent exudate (pus). Abscess exudate consists predominantly of dead/dying neutrophils, cellular debris, and bacteria.
- D. Lymphocytes predominate in chronic inflammation, not in purulent exudate.
