A patient has a dental fistula (sinus tract) that has been present on and off for one year. What are the PRIMARY cells seen in the purulent exudate?
Show answer and explanation
Correct answer: C. Neutrophils
✓ C) Neutrophils is correct.
Pus/purulent exudate is primarily composed of neutrophils (PMNs — polymorphonuclear leukocytes). Neutrophils are the first responders in acute bacterial infection. Even in a chronic fistula, the exudate itself contains predominantly neutrophils. Lymphocytes predominate in chronic granulomatous inflammation of the surrounding tissue. Monocytes differentiate into macrophages in chronic inflammation.
