Spontaneous resolution of persistent lymphadenitis: a case of Kikuchi–Fujimoto disease

Cervical lymphadenopathy is common in all age groups. Persistently enlarged cervical lymph nodes often pose a diagnostic challenge and necessitate focused clinical evaluation with targeted investigations. Pathological examination of excised node yields conclusive answer in the vast majority of cases with unsettled diagnosis. We present a case of a young man with persistent posterior cervical lymphadenopathy which on excision biopsy turned out to be Kikuchi–Fujimoto disease. With watchful follow-up, he had a self-limiting clinical course in the next few months.
