Case report describes diagnostic challenges of Kikuchi-Fujimoto disease in a patient with systemic lupus erythematosus, highlighting improved outcomes with immunosuppressive therapy.
Aims: To describe a rare case of Kikuchi-Fujimoto disease (KFD) secondary to systemic lupus erythematosus (SLE), emphasizing diagnostic challenges, therapeutic approach, and a review of relevant literature. Study Design: Case report. Place and Duration of Study: Department of Medicine, ABVIMS & Dr. RML hospital, over a period of two months in 2024. Methodology: We present an 18-year-old female with a 4-month history of photosensitive malar rash, intermittent fevers, generalized lymphadenopathy, weight loss, and hair thinning. Extensive investigations revealed anemia, transaminitis, hypocomplementemia, and strongly positive ANA (SSA+). PET-CT revealed hypermetabolic lymphadenopathy. Lymph node biopsy showed histiocytic necrotizing lymphadenitis consistent with KFD. The patient fulfilled ACR/EULAR criteria for SLE. She was treated with hydroxychloroquine, corticosteroids and mycophenolate mofetil. Results: Diagnosis of KFD secondary to SLE was established. The patient responded well to immunosuppressive therapy and remains asymptomatic on follow-up. Conclusion: This case highlights the importance of considering KFD-SLE overlap in young females presenting with prolonged fever and lymphadenopathy. Early biopsy and serological work-up are crucial for differentiating from infectious and malignant etiologies.
