Histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease (KFD) is characterized by its rare occurrence. Mostly prevalent among Asian women, KFD manifests with lymphadenopathy-affecting mostly cervical and rarely generalized or retroperitoneal regions-in addition to fever. It is a self-limited disease that resolves within 1-4 months, responding remarkably to glucocorticosteroids or hydr...

To the Editor: Dermatopathic lymphadenitis (DL) represents a rare benign lymphatic hyperplasia commonly associated with exfoliative or eczematoid dermatitis. DL was also reported to be a potential mimicker of lymphoma.[1] Here, we report the 18F‐fluorodeoxyglucose (18F‐FDG) positron emission tomography/ computer tomography (PET/CT) results and the histological findings of a 40‐year‐old female p...

Thirty-six cases of necrotizing lymphadenitis--including 33 cases of unknown etiology, 1 typhoid lymphadenopathy, and 2 cases of suspicious lupus lymphadenopathy--were clinico-pathologically reviewed and analyzed with immunostaining for s-100 and lysozyme. All cases histologically showed architectural effacement by paracortical lesions composed of nuclear karyorrhexis and mononuclear cell proli...

In three pediatric patients with necrotizing lymphadenitis, cytosol aminopeptidase activity (c-AP; EC 3.4.11.1) in serum was markedly increased to 509, 417, and 191 U/L, respectively (normal range 25-60 U/L). Lactate dehydrogenase (LD; EC 1.1.1.27) was also increased, with LD-3 predominating. The increased concentrations of c-AP and LD presumably originated from the destruction of infected, act...

Kikuchi-Fujimoto disease (KFD) is a benign self-limiting disease characterized by fever and lymphadenitis. The etiology and pathogenesis of KFD is unclear. However, two hypotheses have been suggested: a viral infection hypothesis and an autoimmune hypothesis. Several KFD patients with various types of autoimmune diseases have been reported, and these reports support the hypothesis for autoimmun...

Kikuchi’s disease (KD), or histiocytic necrotizing lymphadenitis, is a rare benign and self-limited disease involving young adults, predominantly females. It is rarely described in children. It is characterized by localized lymphadenopathy, often associated with fever and systemic symptoms. The diagnosis is based on histological examination of lymph node biopsy. The disease usually resolves spo...

Kikuchi-Fujimoto disease (KFD), known as subacute necrotizing histiocytic lymphadenitis, is an extremely rare, benign and self-limited disease, and has been infrequently reported with autoimmune diseases. Here we report a 17-year-old girl pathologically diagnosed as KFD who suffered recurrence of KFD and developed into Sjogren's syndrome (SS) after four years and then performed a systematic lit...

Kikuchi-Fujimoto disease (KFD) is a benign and self-limited disorder, characterized by regional cervical lymphadenopathy with tenderness, usually accompanied with mild fever and night sweats. Less frequent symptoms include weight loss, nausea, vomiting, sore throat. Kikuchi-Fujimoto disease is an extremely rare disease known to have a worldwide distribution with higher prevalence among Japanese...

Kikuchi-Fujimoto disease, or histiocytic necrotizing lymphadenitis, is an infrequent idiopathic disorder. It has been associated with autoimmune disorders, of which systemic lupus erythematosus is the most outstanding. The basis of its diagnosis relies on the histological examination of lymph nodes, which typically reveals necrosis surrounded by histiocytes with crescentic nucleus, immunoblasts...
