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

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.
