Kikuchi and Fujimoto disease is a benign subacute necrotizing lymphadenitis, probably associated to a viral infection, that affects mostly young Asian women. We report a 19 years old women, with a vast familiar history of thyroid disease (three uncles with papillary thyroid carcinoma and one with a Hashimoto thyroiditis). After an upper respiratory infection, she presented with painless cervical adenopathies. Cervical ultrasound examination detected an 8 mm thyroidal nodule. She was operated with the diagnosis of thyroidal cancer. The pathological examination confirmed that the nodule was a papillary thyroidal cancer, but the study of the resected lymph nodes, revealed a Kikuchi and Fujimoto disease.

Article Synopsis
- Autoinflammatory disorders are characterized by an exaggerated response of the innate immune system, primarily involving neutrophils and macrophages, and are differentiated from connective tissue diseases by the absence of anti-nuclear antibodies.
- Many of these disorders are linked to inherited genetic mutations and tend to manifest in childhood or early adulthood, though some, like VEXAS syndrome, highlight the potential for acquired mutations in adults.
- The review focuses on the cutaneous manifestations of various acquired autoinflammatory disorders, including adult-onset Still's disease and Schnitzler syndrome, which have significant diagnostic implications.

Kikuchi-Fujimoto disease (KFD) and adult-onset Still disease (AOSD) are two rare conditions whose association poses a significant diagnostic challenge. KFD is characterized by subacute necrotizing lymphadenitis of unknown etiology, primarily affecting young adults, and often presents with fever and posterior cervical lymphadenopathy. AOSD is a systemic inflammatory disorder of unclear origin, defined by high-spiking fever, lymphadenopathy, hepatosplenomegaly, hyperferritinemia, and leukocytosis.

Kikuchi-Fujimoto disease (KFD) is a rare self-limiting condition presenting as fever and cervical lymphadenopathy, with only two reported cases with isolated mediastinal lymphadenopathy. Lack of awareness about this condition often results in a high rate of misdiagnosis. We present a case of a 29-year-old Indian male with fever, mucocutaneous ulcers, weight loss, and mediastinal lymphadenopathy on CT.

Background: Kikuchi-Fujimoto Disease (KFD) is a rare condition, distinguished by its hallmark presentation of regional lymphadenopathy in young adult females. While initially observed to exclusively affect cervical lymph nodes in females under 40 years old, KFD is now known to impact individuals of any age or gender and manifest with adenopathy in various anatomical sites. Nonspecific imaging findings for KFD include enlarged lymph nodes, often exhibiting abnormal morphology.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare, self-limiting disorder characterized by fever typically lasting for 1 week up to 1 month and painful necrotizing lymphadenopathy, primarily affecting young adults of Asian ancestry. Although the exact cause remains unclear, infectious and autoimmune mechanisms have been implicated in the pathogenesis of the disease. In this case series, we aim to describe the histopathological features of KFD over a ten-year period at Mount Sinai Medical Center of Florida, and review the current understanding of its pathogenesis, clinical presentation, diagnosis, and management.
