Kikuchi-fujimoto disease: a case report and literature review

Kikuchi-Fujimoto-like lymphadenopathy following COVID-19 vaccine: diagnosis and management

A woman in her mid 40s presented for breast imaging after 1 week of painful and enlarged right axillary lymphadenopathy. She denied history of fever, weight loss, night sweats fatigue, cat scratch or other trauma. She received the second dose of Pfizer COVID-19 vaccine 3 months previously on the contralateral arm. A mammogram demonstrated a single, asymmetric, large and dense right axillary lymph node. Ultrasound confirmed a 2.5 cm lymph node with cortical thickening of 0.6 cm. Ultrasound-guided core biopsy showed necrotising lymphadenitis with associated aggregates of histiocytes and plasmacytoid dendritic cells. Potential causes of necrotising adenitis including Bartonella, tuberculosis, Epstein-Barr Virus, herpes simplex virus, systemic lupus erythematosus and lymphoma were excluded. In the absence of any identifiable infectious or autoimmune causes, and given the temporal relatedness with vaccine administration, it was determined that the Kikuchi-Fujimoto-like necrotising lymphadenitis was likely secondary to the COVID-19 vaccine. To date, there has been no casual association made between the COVID-19 vaccine and KFD necrotising lymphadenitis.

Kikuchi-Fujimoto disease: A rare case report from Nepal

Clinicians and pathologists must be aware of the occurrence of Kikuchi-Fujimoto Disease, as one of the differential diagnoses of cervical lymphadenopathy.

Case of Kikuchi-Fujimoto disease associated with multiple myeloma

We present a 47-year-old, South-African origin, woman with a background of stable monoclonal gammopathy of unknown significance (MGUS) who attended A&E with a history of coryzal symptoms associated with persistent fever, lymphadenopathy and a new onset of rash, not responding to antibiotics and paracetamol. A trial of high-dose steroids resolved symptoms. Bone marrow biopsy confirmed a progression of MGUS into multiple myeloma and her axillary lymph node biopsy analysis supported a diagnosis of Kikuchi-Fujimoto disease (KFD). This is an unusual presentation where KFD has been noted alongside MGUS progression to multiple myeloma. Haematology follow-up is underway.

Kikuchi-Fujimoto disease: a rare cause of cervical lymphadenopathy and fever

A 28-year-old Pakistani man with previously treated latent tuberculosis (TB) presented with a 3-month history of productive cough, fever, drenching night sweats, anorexia, sore throat and tender left cervical lymphadenopathy. Extensive biochemical and microbiological tests, and imaging studies were all inconclusive. Lymph node biopsy revealed the diagnosis of Kikuchi-Fujimoto disease (KFD). He had persistent fever and anorexia during admission despite supportive measures which resolved quickly on starting prednisolone. He remained well after being weaned off steroids on 18 weeks' follow-up. KFD is a rare, self-limiting disease which can mimic several serious conditions such as TB and lymphoma. Prompt diagnosis with lymph node biopsy is paramount in addressing diagnostic uncertainty and avoids starting potentially toxic treatment on these patients.

Histiocytic necrotising lymphadenitis (Kikuchi-Fujimoto disease) of axillary lymph nodes

Kikuchi-Fujimoto disease (KFD) or histiocytic necrotising lymphadenitis is a rare entity, occurring most commonly in young Asian adults. KFD is characterised by fever with tender lymph node enlargement. The cervical group of lymph nodes is most commonly involved, and the diagnosis is conclusively made by lymph node biopsy and histopathology. KFD is a self-limiting condition, which usually resolves over 1-4 months. Symptomatic treatment with antipyretics and/or non-steroidal anti-inflammatory drugs is recommended. Here we describe an uncommon presentation of KFD in a young woman in which only the axillary lymph nodes were enlarged.

Kikuchi-fujimoto disease: a rare cause of Fever in the returning traveller

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.

The enigmatic kikuchi-fujimoto disease: a case report and review

We report this case of a 33-year-old African American woman who presented to the clinic with preauricular and submandibular masses that she had noticed 6 weeks earlier. She gave a remote history of noticing bilateral cervical masses 3 years prior to this presentation that had not been investigated at the time and resolved spontaneously. Excisional biopsies of the cervical lymph nodes showed morphologic and immunophenotypic findings suggestive of Kikuchi Fujimoto disease (KFD). KFD is an uncommon, self-limited, and perhaps an underdiagnosed entity with an excellent prognosis. It mimics malignant lymphoma in presentation and therefore an accurate clinicopathological differentiation is crucial.
