Abstract
INTRODUCTION Kikuchi-Fujimoto (KF) disease, also known as necrotizing histiocytic lymphadenitis, is a rare cause of fever of unknown origin. Most commonly seen in Japanese populations, it presents with fever and diffuse lymphadenopathy. KF can present a diagnostic challenge as its presentation can mimic sepsis, autoimmune disease, and/or malignancy. We present a case of KF disease presenting with innumerable pulmonary nodules and suspected sepsis. CASE REPORT A 24-year old African-American male inmate with no past medical history presented to the Emergency Department with two witnessed generalized tonic-clonic seizures. Initial vitals were notable for a fever of 101.5 F, tachycardia, and tachypnea. He was lethargic with a diffuse, erythematous, scaly, necrotic rash. Additionally, cervical, axillary, and inguinal mobile, non-tender lymph nodes were noted. Laboratory studies revealed white blood cells 1.9 × 10 3 cells/μL with 25% bands, hemoglobin 9.4 G/dL, and platelet count of 110 × 10 3 cells/μL. He was subsequently admitted for sepsis due to presumed meningitis and started on broad-spectrum antibiotics. Lumbar puncture revealed no pleocytosis. Peripheral blood smear showed bandemia with Pelger Huet cells. Computed Tomography of chest, abdomen, and pelvis with contrast revealed diffuse pulmonary nodules involving all lobes of the lungs in addition to bulky hilar and retroperitoneal lymphadenopathy. Interventional Radiology performed a retroperitoneal lymph nodes biopsy that revealed lymphoplasmacytic cell infiltrate with extensive necrosis. Otolaryngology performed an excisional biopsy of a lymph node, which showed histiocytic necrotizing lymphadenitis. The final diagnosis was Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis. OUTCOME The patient completed a 7-day course of empiric antibiotics. Workup for infectious etiologies was negative. The patient had a repeat CT of the chest with interval resolution of his pulmonary nodules on outpatient follow-up. CONCLUSION Patients with innumerable pulmonary nodules and fever of unknown origin should be evaluated early in their hospital course for KF as early diagnosis can reduce excessive testing and shorten hospital stay.

Abstract
Kikuchi-Fujimoto disease (KFD) is a rare entity characterized by subacute necrotizing lymphadenopathy and frequently associated with fever. Young adults of Asian ancestry are most commonly affected, but it has been reported worldwide. Despite many studies in the literature, the cause of KFD remains uncertain. Histologically, KFD is characterized by paracortical lymph node expansion with patchy, well-circumscribed areas of necrosis showing abundant karyorrhectic nuclear debris and absence of neutrophils and eosinophils. Three evolving histologic patterns-proliferative, necrotizing, and xanthomatous-have been recognized. By immunohistochemistry, histiocytes in KFD are positive for myeloperoxidase. There is a marked predominance of T cells in the lesions (with mostly CD8-positive cells) with very few B cells. The differential diagnosis of KFD includes infectious lymphadenitis, autoimmune lymphadenopathy (primarily systemic lupus erythematosus), and lymphoma. Clinicians and pathologists are poorly familiar with this entity, which frequently causes significant diagnostic challenges.

Abstract
Generalized lymphadenopathy after organ transplant is a concerning finding, often indicating the devel-opment of lymphoma. We describe a 52-year-old liver transplant recipient who had clinical symptoms and imaging concerning for posttransplant lymphoproliferative disease. However, histologic evaluation of a lymph node biopsy revealed that the patient actually had a much rarer but relatively benign condition, Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis). We discuss the epidemiology, clinical symptoms, diagnosis, histologic features, and treatment of this uncommon mimic of posttransplant lymphoproliferative disease.

Abstract
Kikuchi-Fujimoto disease is a necrotizing lymphadenitis, involving young patients, predominantly females. Lymphadenopathy is usually localized, particularly in the cervical area, mostly unilateral and tender. Fever is present in one third of cases. Associated skin lesions, arthralgia, myalgia, splenomegaly or hepatomegaly are rare. Laboratory evaluation shows a slight increase of erythrocyte sedimentation rate and leukopenia. Kikuchi-Fujimoto has been reported in association with other diseases, including systemic lupus, Still's disease, hemophagocytosis, pregnancy, other autoimmune diseases, and cancer. A viral or bacterial origin has been suspected but not confirmed. Lymph node biopsy allows the diagnosis and shows necrotizing lymphadenitis with acidophil necrosis, CD68+ histiocyte infiltrate, presence of plasmacytoid monocytes, multiple apoptotic cells (CD8+ T cell) with nuclear dust, immunoblastic reaction and the absence of neutrophils or eosinophils. The disease course is usually spontaneously favourable in few weeks or months, requiring corticosteroids only occasionally.

Abstract
Kikuchi-Fujimoto disease (KFD), first described independently by Kikuchi and Fujimoto in 1972, is a subacute necrotizing lymphadenitis of unknown cause. Although most frequent in young Asian women, KFD has a worldwide distribution. Clinically, KFD is characterized by lymphadenitis of one or more lymph nodes, predominantly in the posterior cervical region, fever, and leukopenia in up to 50% of cases. Extranodal manifestations can occur, especially skin lesions and aseptic meningitides. Diagnosis is usually confirmed by analysis of samples from an excisional biopsy of the affected nodes. Histologically, the lesions affect the cortical and paracortical areas of the node. Characteristic features include focal necrosis predominantly in the paracortical region with abundant karyorrhectic debris and atypical mononuclear cells around the necrotic zone (crescent-shaped histiocytes, plasmacytoid monocytes, and small lymphocytes and immunoblasts, mostly CD3(+)/CD8(+)), most often with an intact lymph node capsule, an absence of neutrophils, and a paucity of plasma cells. KFD has been classified into three histological subtypes and is thought to progress from the proliferative type (> 50%) to the necrotizing type (30%) and finally resolve into the xanthomatous type (< 20%). Differential diagnoses should include malignant lymphoma, infectious diseases such as toxoplasmatic lymphadenitis, tuberculous lymphadenitis and cat scratch disease, and systemic lupus erythematosus (SLE). The cause of KFD is unknown: a viral infection has been suggested, but not demonstrated, possibly involving human herpes virus 8 or Epstein-Barr virus. Apoptotic cell death plays a role: proliferating CD8(+) T-lymphocytes act as both killers and victims in the apoptotic process via Fas and perforin pathways. The course is usually benign with resolution in a few months with the use of antiinflammatory drugs. Regular follow-up is required because SLE may develop several years after the onset of Kikuchi-Fujimoto disease.

Abstract
Kikuchi-Fujimoto disease (KFD) is subacute necrotizing lymphadenitis characterized by fever, leukopenia and cervical lymphadenopathy. There are few reports on the clinical characteristics and laboratory findings of KFD in the pediatric literature. In this study, we evaluate the characteristics and outcome of KFD in children. A total of 412 patients were studied with fever and peripheral lymphadenopathy at Pusan National University Hospital from January 1998 to December 2003. Among the total 412 there were 16 patients diagnosed with KFD by lymph node biopsy. We analyze the clinical, laboratory and outcome after review of the medical records retrospectively. The mean age of the patients was 10.6 +/- 3.4 yr (range: 4-17 yr). The male to female ratio was 1:1. Almost all patients, except two, had cervical lymph node swelling. The size of the involved lymph node was less than 4 cm in the greatest dimension in 75% of the patients. All the children had fever as the chief complaint and the mean duration of the fever was 17.7 +/- 11.2 days (range: 2-122 days). Approximately 87% of the patients had leukopenia (WBC < 4000/mm(3)) and 43.8% of the patients had a mild increase in the transaminases on liver function testing. A total of 8 out of the 16 patients were initially misdiagnosed as an infectious disease and treated with antibiotics which caused prolonged hospitalization for most patients. Six patients were treated with prednisone and the prolonged fever subsided immediately after steroid therapy. KFD should be considered in the differential diagnosis of prolonged fever in children with cervical lymphadenopathy. Early cervical lymph node biopsy is necessary to minimize inappropriate examinations and treatments in such cases.

Abstract
Kikuchi-Fujimoto Disease (KFD) was first described in Japan in 1972. The disease frequently mimics tuberculous lymphadenitis, malign lymphoma, and many other benign and malignant conditions. To our knowledge, there is no previous study comparing the clinical and laboratory characteristics of patients from different geographical parts of the world. We searched literature records beginning from 1991 and analyzed epidemiological, clinical, and laboratory data of 244 patients (including cases diagnosed in our institution) reported in 181 publications. Of the 244 cases, 33% were male and 77% were female. Mean age was 25 (1-64) and 70% was younger than 30. Most of the cases were reported from Taiwan (36%), USA (6.6%), and Spain (6.3%). Fever (35%), fatigue (7%) and joint pain (7%) were the most frequent symptoms, while lymphadenomegaly (100%), erythematous rashes (10%), arthritis (5%), hepatosplenomegaly (3%), leucopenia (43%), high erythrocyte sedimentation rate (40%), and anemia (23%) being the most common findings. KFD was associated with SLE (32 cases), non-infectious inflammatory diseases (24 cases), and viral infections (17 cases). SLE was more frequent in cases from Asia than Europe (28 and 9%, respectively). The disease was self-limiting in 156 (64%) and corticosteroid treatment was necessary in 16 (16%) of the cases. The mortality rate was 2.1%. Early diagnosis is crucial as the clinical and laboratory presentation generally imitates situations needing lengthy and costly diagnostic and therapeutic interventions. Additionally, association with SLE needs further investigation.

Abstract
We report a case of Kikuchi-Fujimoto disease (KFD) in a 28-year-old pregnant woman with prolonged fever and generalized lymphadenopathy. We evaluated the patient for etiology of the fever and adenopathy, which were unresponsive to antibiotic therapy. Cervical lymph node histology showed KFD. Currently, there is scant data available regarding the course and treatment of KFD during pregnancy. We administered steroid therapy (prednisone 1 mg/kg/day) to control severe systemic and constitutional symptoms. We observed a reduction in lymph node size as well as abatement of fever and other constitutional symptoms. The patient carried the fetus to full term with no apparent adverse effect. Our experience showed that steroid therapy may be used effectively to control KFD-related symptoms after the first 16 weeks without terminating the pregnancy.

Abstract
We describe a young woman with two severe episodes of Kikuchi Fujimoto disease occurring 16 years apart. Both episodes were proven by biopsy, and on the second occasion the patient remained dependent on high-dose prednisone for more than 6 months in order to control inflammation and achieve a reduction in cervical lymph node size. The second lymph node biopsy showed leukocytoclastic vasculitis in addition to the typical features of Kikuchi Fujimoto disease, but, even though the clinical interpretation of this finding was unclear, we documented no clinical or laboratory evidence of the development of other serious systemic disease over 20 years of follow-up. Kikuchi Fujimoto disease is considered a disorder with a self-limited course and a favorable outcome. However, on the basis of our experience with this patient and data from peer-reviewed literature, we suggest that this generally accepted postulate should be revised.

Abstract
Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, was initially described as a distinct histologic pattern of lymphadenitis generally associated with a benign self-limited clinical course. While most common in Southeast Asia, where KFD was initially described in 1972 in young women, this lesion has since been reported in patients of virtually any age, gender, or ethnic background from a variety of geographic locations, including the United States. In addition, cases showing extranodal involvement have been described. The spectrum of clinical and histologic features associated with this disorder suggest that KFD more likely represents a common pattern of response to a variety of etiologic factors rather than a single clinicopathologic entity. In this review, the characteristic clinical, laboratory, histologic, and immunophenotypic features of this disorder are described, with emphasis on differential diagnosis with other types of necrotizing lymphadenitis and with malignant lymphoma. Unusual clinical presentations and features of disease when present at extranodal sites are also reviewed.

Abstract
We describe a rare but typical case of Kikuchi-Fujimoto disease (KFD). Two subcutaneous nodules appeared suddenly on the right of the neck of a 15-year-old girl. Microscopy of a surgical specimen of the larger nodule showed necrotizing lymphadenitis. Prompt treatment with mepirizole resulted in the disappearance of the smaller nodule. No recurrence was noted during 6 months of follow-up. KFD is a rare, self-limiting, necrotizing histiocytic lymphadenitis that needs to be differentiated from malignant lymphoma. Any nodal biopsy showing fragmented nuclei, necrosis, and karyorrhexis without prominent neutrophils should alert the physician to consideration of KFD, especially in a young woman presenting with cervical lymphadenopathy.

Abstract
Kikuchi's histiocytic necrotizing lymphadenitis is a self-limited disorder that typically involves the cervical lymph nodes of young women. Although a viral etiology has been postulated, a definitive viral agent has not been identified. Recent reports have suggested that human herpesvirus 8 (HHV 8) or Epstein-Barr virus (EBV) may play an etiologic role. We investigated the presence of HHV 8 and EBV in archival tissue from 34 cases of Kikuchi's histiocytic necrotizing lymphadenitis. We examined 29 cases for HHV 8 using a nested polymerase chain reaction (PCR) on paraffin-embedded or frozen tissue, and 24 cases for EBV RNA using in situ hybridization (ISH) for EBER1. Controls included reactive lymph nodes from 8 adult women presenting with cervical or axillary lymphadenopathy. The study patients included 7 men and 27 women with a mean age of 28 years. All patients were previously healthy without evidence of immunocompromise and presented with cervical, axillary, or inguinal lymphadenopathy. Two cases exhibited EBV RNA by ISH; this was confirmed by PCR for EBV DNA. HHV 8 DNA was not amplified by nested PCR in any of the cases of Kikuchi's histiocytic necrotizing lymphadenitis or reactive lymph nodes; control PCR demonstrated the presence of amplifiable DNA in all cases. These findings suggest that HHV 8 and EBV do not play causative roles in Kikuchi's histiocytic necrotizing lymphadenitis.
