Cervical lymphadenopathy can be developed from various causes such as viral infection, bacterial infection, Kikuchi-Fujimoto disease, tuberculosis, malignancy, and reactive changes. In patients who have malignancy, metastatic lymphadenopathy is possible but it is rare that other concomitant diseases are in the same lymph node. We experienced a case of coexistence of Kikuchi necrotizing lymphade...

Kikuchi-Fujimoto disease was initially described as a self-limiting histiocytic necrotizing lymphadenitis in Japan in 1972, and is predominantly observed in women under the age of 30 year and in Asian populations. The pathogenesis is still poorly understood but is thought to include infections, and autoimmune and neoplastic diseases. The most common clinical manifestations are fever and painles...

Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The...

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...

A group of patients with Kawasaki disease (KD) initially present with cervical lymphadenitis or deep neck infection. These unusual KD presentations lead to unnecessary antibiotic therapy or surgical intervention, thereby delaying intravenous immunoglobulin treatment and increasing the risk of coronary artery damage. We present four KD patients whose initial presentations mimicked a retropharyng...
