Summary
This case report details a young woman with Kikuchi's lymphadenitis, presenting with neck mass and fever. Symptoms resolved within two months post-biopsy, indicating a self-limiting course for this rare condition.
Area of Science:
- Immunology
- Pathology
- Oncology
Background:
- Kikuchi's lymphadenitis (KL) is a rare, benign condition of lymph nodes.
- It primarily affects young adults and can mimic malignant lymphoma.
- Accurate diagnosis is crucial to avoid unnecessary aggressive treatments.
Observation:
- A young Asian female presented with cervical lymphadenopathy, pharyngitis, fever, and malaise.
- Clinical symptoms improved rapidly following a lymph node biopsy.
- Serological tests confirmed prior Epstein-Barr virus (EBV) infection and ruled out other infectious agents.
Findings:
- Histopathology revealed lymph node necrosis and infiltration by lymphocytes, immunoblasts, macrophages, and plasmacytoid monocytes.
- Immunohistochemistry showed a predominance of CD4+ T-lymphocytes within the lesions.
- Neutrophils were notably absent in the affected lymph node tissue.
Implications:
- This case highlights the importance of considering KL in the differential diagnosis of cervical masses and fever.
- The rapid improvement post-biopsy suggests a favorable prognosis for KL.
- Understanding the specific T-lymphocyte subset involvement may offer insights into KL pathogenesis.
