Abstract
Kikuchi-Fujimoto disease (KFD), or histiocytic necrotizing lymphadenitis, is a benign but rare disorder associated with febrile cervical lymphadenopathy in young adults. Here, we discuss a case of a young female patient presenting with left tender cervical lymphadenopathy that progressed bilaterally with a fever of unknown origin. Laboratory parameters showed persistent leukopenia, especially neutropenia, which fluctuated with the degree of symptom severity. Two months were taken to confirm the diagnosis of KFD based on the histological interpretation of the lymph node biopsy. Supportive management with analgesics and paracetamol formed the main treatment. This case highlights the challenges and importance of diagnosing KFD to exclude other serious conditions such as lymphoma, tuberculosis, or lupus lymphadenitis that share similar clinical manifestations as KFD.

Abstract
Background Kikuchi-Fujimoto disease (KFD) - also known as necrotizing histiocytic lymphadenitis - is a benign histiocytic lymphadenitis known for its low incidence and misdiagnosis that occurs mostly in young Asian females more than males. This disease resolves spontaneously in a few months with a low risk of relapse (one in 30 patients) after resolution. Objectives The aim of this study is to share King Abdulaziz Medical City's (KAMC's) experience with KFD by determining its clinicopathological characteristics. Materials and methods In this study, we reviewed histopathological slides and pathological reports of all lymphadenopathy cases (683 cases) in the period between January 2008 and December 2018. Results Forty-four cases of KFD were found and their clinicopathological characteristics were recorded. There is a slight female predominance (59% females versus 41% males) with a wide age range from 10 months to 97 years (mean = 28.8). The majority of the cases (63.6%) are seen in young adults (between 21 and 40 years). Association with autoimmune diseases was shown by 20.5% of cases while viral infection association was shown by few cases. Most cases showed remission (59%) and no deaths were reported upon follow-up. Histopathologically, the majority of cases have proliferative type followed by the necrotic type and few cases showed xanthomatous type. Conclusions Our study has the largest number of KFD cases in this region. It is obvious that KFD has clinical, radiological, and pathological features that overlap with malignancy, especially lymphoma. Knowing this disease and careful diagnostic approach can help avoid misdiagnosis.

Abstract
Background: Kikuchi-Fujimoto disease (KFD) is a rare, benign condition of unknown etiology, presenting as cervical lymphadenitis. Lymphadenopathy is usually tender and maybe associated with systemic symptoms. Despite the extensive literature on this disease, it continues to be misdiagnosed owing to its misleading clinical presentation.
Methods:
A retrospective hospital-based descriptive cross-sectional study was conducted in tertiary care hospitals from 2011 to 2019. All patients with confirmed KFD diagnosis were included and after ethics committee approval the clinical details and histopathological data was retrieved from the medical records department and analyzed.
Results:
A total of 67 cases were included. The mean age was 26.9±11.3 years with a female: male ratio of 1.9:1. There were 50 patients with tender cervical lymphadenopathy which was the most common clinical presentation. The mean length and width of palpable lymph nodes were 2.3±1.0 cm and 2.2±0.7 cm respectively. Histology revealed proliferative stage in majority of patients (
n=40, 59.7%). Lymphadenopathy resolved in 83.6% within 2 months. There were 42 patients who had complete recovery with symptomatic treatment within a period of 9 months.
Conclusions:
KFD is prevalent in young, female patients of Asian descent and often presents as tender cervical lymphadenopathy. Early diagnosis with excisional lymph node biopsy is crucial to avoid unnecessary investigations and treatment. Treatment is symptomatic unless complicated, where steroid therapy is considered. KFD has an excellent prognosis with almost no risk of fatality.

Abstract
Kikuchi-Fujimoto disease (KFD) is a rare benign disease, clinically characterized by fever and tender cervical lymphadenopathy affecting the posterior cervical lymph nodes. This disease is usually accompanied by night sweats, rashes, and headaches. It generally affects young individuals, especially females, of Oriental-Asian origin. The etiology of KFD remains uncertain, but associations have been noted with viral diseases including Epstein-Barr virus (EBV), herpes simplex virus (HSV), and varicella-zoster virus (VZV), as well as autoimmune disorders including systemic lupus erythematosus (SLE) and Sjogren's syndrome. This review points out the etiology of KFD with cervical lymphadenopathy alongside its clinical presentation, histological highlights, lab investigations, complications, and treatment. Accurate diagnosis of this disease depends on lymph node excisional biopsy. Three histological patterns of KFD are recognized: proliferative, necrotizing, and xanthomatous. Distinction from lymphadenopathy-associated alternate disorders (e.g., SLE, malignancy, tuberculosis, or another infectious lymphadenitis) is essential to ensure appropriate therapy. This self-limited condition entails nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief with consideration of corticosteroids and hydroxychloroquine in severe cases.

Abstract
BACKGROUND Necrotizing lymphadenitis is a rare disease. It is often misdiagnosed because of the lack of typical clinical manifestations. It is worth noting that necrotizing lymphadenitis may be a precursor lesion of systemic lupus erythematosus or tumours, so regular follow-up is needed to facilitate early diagnosis. Here, we report a case and conduct a literature analysis summarizing the clinical features of necrotizing lymphadenitis and its treatment and management practices. CASE PRESENTATION A 16-year-old young woman presented with fever and lymphadenopathy as the main clinical manifestations, accompanied by a rash during fever that disappeared as the fever subsided. After completing imaging and laboratory examinations, we excluded other diseases such as infections, autoimmune diseases, and malignant tumours. Finally, we diagnosed the patient with necrotizing lymphadenitis based on the results of lymph node biopsy. The symptoms of the patient improved after glucocorticoid treatment, and she was followed up for half a year without recurrence of symptoms. CONCLUSION In the clinic, young women with fever and lymphadenopathy as major symptoms should be screened for necrotizing lymphadenitis to facilitate early diagnosis and treatment. Although necrotizing lymphadenitis is self-limiting, its clinical manifestations are similar to those of many diseases. Therefore, it is easily misdiagnosed. An in-depth understanding of the disease is conducive to early diagnosis and treatment in the clinic, thereby reducing further damage to the body and reducing unnecessary evaluation and treatment.

Abstract
Introduction Kikuchi-Fujimoto (KF) disease is a rare and self-limiting disorder of unknown aetiology characterized by cervical lymphadenopathy (CLN) and fever. The pathophysiology remains unclear and may be triggered by an infectious agent leading to a self-limiting autoimmune process. There are no confirmatory laboratory tests and lymph node biopsy is required to differentiate KF disease from other serious conditions. Materials and methods We report 11 cases of KF disease diagnosed at Hamad General Hospital, Qatar, between 2006 to 2016. The diagnosis is based on clinical presentation, investigations and histopathological examination of lymph nodes. Results All patients had painful neck swelling (average duration of 2.9 weeks) and 10 had fever (average duration of 3.2 weeks). Five patients developed mild leucopenia which resolved completely. HIV and tuberculosis (TB) screening including sputum for AFB, a PPD skin test and chest x-ray was done for all patients and came back negative. Autoimmune screening was done for all patients and excluded any rheumatological disease. Ultrasound and CT of the neck confirmed cervical lymphadenopathy. Except for hepatomegaly in one patient, CT scans of the chest and abdomen were negative for any lymphadenopathy or organomegaly (performed in seven patients). Diagnosis was confirmed on lymph node excision biopsy. Histopathological examination showed findings consistent with the diagnosis of histiocytic necrotizing lymphadenitis (KF disease). Conclusion KF disease should be kept in mind for patients presenting with fever and CLN. Lymphoma, TB and autoimmune diseases like systemic lupus erythematosus should be excluded in such patients.

Abstract
Background Kikuchi Fujimoto disease is an uncommon benign condition of necrotizing histiocytic lymphadenitis commonly seen in East Asian and Japanese populations. It commonly presents with fever, cervical lymphadenopathy, and elevated inflammatory markers. Diagnosis of Kikuchi Fujimoto disease is based on histopathological studies of the involved lymph nodes. The presentation of Kikuchi Fujimoto disease can mimic many sinister conditions including lymphoma. Treatment is mainly supportive provided that accurate diagnosis is made and sinister conditions like lymphoma ruled out. Case presentation We report the case of an 18-year-old Sri Lankan Moor woman who presented with fever and cervical lymphadenopathy for 1 month. She had elevated inflammatory markers with high lactate dehydrogenase and ferritin levels. She had an extensive work-up including an excision biopsy of an involved lymph node and bone marrow biopsy. Finally, a diagnosis of Kikuchi Fujimoto disease was based on histopathology of the lymph node and negative bone marrow biopsy. Conclusions Although Kikuchi Fujimoto disease is a self-limiting condition, it is a great masquerader which mimics the clinical features of many sinister conditions including tuberculosis, lymphoma, and adult-onset Still’s disease. Early recognition of the disease is of crucial importance in minimizing potentially harmful and unnecessary evaluations and treatments.

Abstract
Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare self-limiting disorder typically affecting the cervical lymph nodes (LNs), which is often misdiagnosed as other LN-associated diseases. KFD frequently presents with necrotic lesions and recurrences, which are also features of metastatic LNs. Clinicians may thus suspect LN metastasis when they encounter ipsilateral cervical lymphadenopathy in a patient with head and neck cancer. The present study reports the case of a 48-year-old man with tongue cancer and KFD affecting the right edge of his tongue and ipsilateral cervical LNs. LN metastasis was initially suspected, but pathological examination of the dissected LNs revealed one necrotic metastatic lesion and two necrotic KFD lesions. Ipsilateral cervical lymphadenopathy recurred 6 years after the initial surgery, and it was not possible to differentiate clinically between a second primary tumor and recurrent KFD prior to treatment. To the best of our knowledge, this is the first reported case of simultaneous tongue cancer, regional LN metastasis and KFD. This highlights the requirement to consider KFD in the event of LNs with necrotic lesions but no cancerous cells. A combination of clinical and pathological approaches may aid in the diagnosis of KFD, in addition to ruling out LN metastasis in initial and recurrent lymphadenopathies. The present study indicate that a diagnosis of KFD should be considered in patients with head and neck cancer that exhibit necrotic LNs lacking cancerous cells. This is important, as misdiagnosis of KFD as LN metastasis may lead to unnecessary adjuvant therapy.

Abstract
A 29-year-old British Pakistani woman presented with a 2-month history of drenching fevers, night sweats, lethargy and tender cervical and axillary lymphadenopathy. Initial investigations, bloods and imaging were unremarkable. Fever persisted during her admission, and treatment for tuberculosis (TB) lymphadenitis was started postbiopsy until histology confirmed a diagnosis of Kikuchi-Fujimoto's disease (KFD). KFD has a non-specific presentation of fever, night sweats and lymphadenopathy and commonly raises a clinical suspicion of a number of other serious conditions such as TB, lymphoma, HIV, systemic lupus erythematous, toxoplasmosis and infectious mononucleosis. Although rare, KFD should be considered to be a differential diagnosis for fever of unknown origin and tender lymphadenopathy in otherwise well individuals. This case demonstrates the importance of a timely histological biopsy diagnosis to prevent an incorrect diagnosis and administration of unnecessary medications.

Abstract
Kikuchi-Fujimoto disease (KFD) is a benign, self-limiting disease characterized by histiocytic necrotising lymphadenitis. Though several viral agents or an autoimmune etiology has been proposed as causative, the exact cause remains unknown. It has a female predilection and most commonly seen among young Asian people. Patients usually present with a febrile illness and the presence of lymphadenopathy may provide a clue to diagnosis. The most common site of lymphadenopathy is cervical lymph nodes while intra-abdominal involvement is uncommon. Cases of KFD presenting with intra-abdominal lymphadenopathy have been reported to occur with equal frequency in both sexes. Abdominal tuberculosis, non-Hodgkin's lymphoma, and systemic lupus erythematosus are close differential diagnoses for this type of presentation. Treatment is mostly supportive as the disease usually resolves spontaneously; steroids are only required in severe cases. We report a 32-year-old male patient of intra-abdominal lymphadenitis that presented as fever of unknown origin (FUO) and diagnosed by excisional biopsy as a case of KFD.

Abstract
Background. Kikuchi-Fujimoto disease (KFD) is typically a self-limited, benign illness which presents with fever and lymphadenopathy. It is rare in Caucasians, normally occurring in those of Asian descent. The aetiology is poorly understood, but it appears to be an autoimmune disorder with a possible infectious trigger. The clinical features are such that it is often mistaken for infectious diseases or malignancy. Case Report. Here we describe a case of a 36-year-old Asian man who presented following a recent trip to Delhi, India. He described fever, neck swelling, and arthralgia. Given his travel history an infectious cause for his presentation was presumed but multiple investigations were negative. Persistence of his symptoms led to lymph node biopsy to investigate for malignancy; surprisingly this revealed a necrotizing lymphadenitis in keeping with KFD. The patient made a full recovery with supportive treatment only. Conclusion. This case presented an opportunity to reflect on two common presenting complaints-fever in the returning traveller and unexplained lymphadenopathy. Both presentations have a wide range of aetiologies to consider. Although KFD is rare, it is an important diagnosis to make as it can prevent further expensive and invasive investigations, as well as potentially harmful treatments and psychological stress to the patient.
