Kikuchi disease.

Area of Science:

• Immunology
• Pathology

Background:

• Kikuchi-Fujimoto Disease (KFD), also known as necrotizing lymphadenitis, is a rare, benign, and self-limiting disorder.
• It predominantly affects young females in their third decade, with cervical lymphadenopathy being the most common clinical presentation.
• The exact etiology of KFD remains controversial, necessitating a combination of diagnostic approaches.

Observation:

• Diagnosis relies on clinical findings, histological examination, and immunohistochemistry.
• The case involved a female patient presenting with tender cervical lymphadenopathy, diagnosed via excision biopsy.
• Initial treatment with anti-inflammatory drugs resulted in a brief relapse.

Findings:

• Steroid therapy has demonstrated efficacy in alleviating symptoms, particularly in cases with systemic manifestations.
• The patient experienced remarkable improvement following the initiation of steroid therapy after a relapse.
• Antibiotic use is contraindicated unless an infectious agent is definitively identified.

Implications:

• Early diagnosis and appropriate treatment, such as steroid therapy for systemic symptoms, are crucial for managing KFD.
• This case highlights the effectiveness of steroids in managing KFD, especially in preventing relapses.
• Understanding the diagnostic criteria and treatment options is vital for clinicians managing patients with suspected KFD.
