Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis) is a rare disease characterized by lymphadenitis with
fever. It is self-limited within one to four months, and is generally diagnosed by an excisional biopsy of the affected
lymph node. Kikuchi-Fujimoto disease has a wide variety of nonspecifi c symptoms and it is sometimes misdiagnosed as
malignant lymphoma, lymph node tuberculosis, or systemic lupus erythematosus. Because clinical course and treatment
of this disease differ from those of others, Kikuchi-Fujimoto disease must be included in differential diagnosis of enlarged
lymph node. In this report, we discribed a case of 24-year-old male patient who visited the clinic complaining of fever,
petechiae, and enlarged lymph node. He was diagnosed as Kikuchi-Fujimoto disease and immune thrombocytopenic
purpura.
