# When Rare Meets Reality: A Case of Kikuchi-Fujimoto Disease in Tertiary Care Center

## TL;DR

This paper presents a rare case of Kikuchi-Fujimoto disease in a 42-year-old woman, highlighting the importance of histological diagnosis for similar conditions.

## Contribution

The novelty lies in reporting a rare disease case with clinical features and treatment response in a tertiary care setting.

## Key findings

- The patient showed cervical lymphadenopathy and constitutional symptoms, typical of Kikuchi-Fujimoto disease.
- Symptoms improved with cefepime and nonsteroidal anti-inflammatory drugs.
- Histological evaluation was crucial for accurate diagnosis and treatment guidance.

## Abstract

Kikuchi-Fujimoto disease is a very rare disease, basically involving young adults and ubiquitously distributed. It is characterized by fever and benign lymph node swelling. The distinguishing features of this disease are cervical lymphadenopathy, constitutional symptoms resembling tuberculosis, and its penchant to affect young people of Oriental or Asian descent, especially women. We describe an instance of a 42-year-old female who arrived with multiple neck swellings. On physical examination, there was palpable right-sided cervical lymphadenopathy, while laboratory investigations were essentially within normal limits except for raised erythrocyte sedimentation rate and anemia. After cefepime and nonsteroidal anti-inflammatory medications were administered, symptoms subsided, and lymphadenopathy receded in the patient. This case supports the importance of histological evaluation to reach an exact diagnosis and guide treatment and the need to consider Kikuchi-Fujimoto disease in the differential diagnosis of lymphadenopathy.
