Here is a clear breakdown of this FNAC report:

FNAC Report Summary — Shaikh Zaheruddin, 48Y Male

Site: Left cervical lymph node Swelling: 1×1 cm, firm, non-tender

What the Smear Showed

  • Plenty of lymphocytes — the dominant cell population
  • Few sinusoidal fibers
  • Few neutrophils and macrophages
  • Hemorrhagic background (blood mixed in the aspirate — common with neck lymph node FNACs)

What Was Ruled Out

  • ❌ No granulomas — tuberculosis (TB) is excluded
  • ❌ No malignancy — no cancer cells seen

Diagnosis: Non-Specific (Reactive) Lymphadenitis

This is a benign, reactive enlargement of the lymph node. The node is responding to some infection or inflammatory stimulus — it is NOT cancer and NOT TB.

What This Means Clinically

Reactive/non-specific lymphadenitis is the most common cause of cervical lymph node swelling. The node enlarges because of:
  • Hyperplasia of B lymphocytes, T lymphocytes, and macrophages inside the node
  • Often triggered by throat infections, dental infections, bacterial pharyngitis, or viral illnesses (the most common sources for neck node enlargement)
As Robbins Pathology explains: "Infections and nonmicrobial inflammatory stimuli often activate immune cells residing in lymph nodes... Any immune response against foreign antigens can lead to lymph node enlargement." The firm, non-tender character fits chronic non-specific lymphadenitis.

What Should Happen Next

Since the FNAC was referred by an ENT surgeon (Dr. Mohammed Nusarat Jeelani), the next steps would typically be:
  1. Identify and treat the source — ENT examination for throat, tonsil, teeth, or ear infection
  2. Antibiotics if a bacterial cause is suspected
  3. Follow-up in 4–6 weeks to confirm the node regresses with treatment
  4. If the node persists or grows, further workup (CT scan, excision biopsy) may be needed to exclude lymphoma or other causes
This is a reassuring result — no cancer, no TB. The node is reacting to something treatable.
