Kikuchi–Fujimoto disease, also known as “histiocytic necrotizing lymphadenitis,” is a rare, benign disease that commonly affects young females. Patient usually presents with swollen lymph nodes in neck (cervical lymphadenopathy), fever, night sweats, weight loss, nausea, and vomiting. Due to the similar symptomatology, the disease is often confused with tuberculosis and lymphomas. The exact cause remains unknown with no evidence of inheritance. The diagnosis is confirmed by histopathologic examination of lymph node biopsy, which reveals necrosis (that varies considerably from one case to another), histiocytes (contains phagocytosed debris), crescentic nuclei, karyorrhexis, and plasmacytoid monocytes. The disease is self-remitting within 1 to 4 months. However, nonsteroidal anti-inflammatory drugs (NSAIDs), oral corticosteroids, and hydroxychloroquine may be used for symptomatic relief.

| Case Report|| |
A 16-year-old female presented to tertiary care health center in North India with complains of multiple small swellings in infra-auricular region on right side of neck for 2 months. Swellings were accompanied by localized pain, tenderness, and fever. Fever was low grade, intermittent, and relieved on taking antipyretic medications.,,,
Patient consulted a near-by physician, who advised Mantoux test and fine-needle aspiration cytology (FNAC) of the swollen lymph node and started antitubercular treatment (ATT) on empirical basis. Mantoux test revealed induration of 12 mm, whereas FNAC revealed lymphoid cells in various stages of maturation along with occasional neutrophils and scattered epitheloid cells. Patient took ATT for 15 days but was not relieved symptomatically and was referred to tertiary health center.
On local examination, multiple small discrete, rounded swellings were palpable in neck on right side, of 1 to 2 cm in size. Swellings were firm in consistency with signs of local inflammation (tenderness and local temperature was raised) present.
Contrast-enhanced commuted tomography for neck and chest was performed, which revealed multiple, heterogeneously enhancing lymph nodes in various stations of cervical lymph nodes (Ib, II, III, IV, and V) with largest measuring 2 cm in short axis. However, no evidence of necrosis or calcification was noticed [Figure 1].

Patient was then advised repeat FNAC of the lymph node, and the FNAC smears showed mixed population of histiocytes with crescent-shaped nuclei and phagocytes, along with plasmacytoid monocytic cells, and few plasma cells. Background shows nuclear karyorrhexis. No well-defined granuloma formation was identified [Figure 2] and [Figure 3].

The diagnosis of Kikuchi–Fujimoto disease was confirmed histopathologically and patient was started on NSAIDs (aceclofenac and paracetamol combination). Patient was followed up every 2 weekly. The local inflammation subsided after 2 weeks and the size of lymph node also became subcentimetric. After 6 weeks of therapy, swellings were almost nonpalpable.
| Discussion and Conclusion|| |
In India, though tuberculosis being the most common cause of cervical lymphadenopathy, every clinician must try to obtain the evidence of tuberculosis, before starting the ATT. The other causes of cervical lymphadenopathy, such as lymphomas, Kikuchi–Fujimoto disease, and sarcoidosis, though rare must be ruled out.
