Kimura Disease: A Rare and Difficult to Diagnose Entity.

Kimura disease (KD) is a rare inflammatory disorder which involves the head and neck. Due to its rarity and various findings, definitive diagnosis can be difficult to ascertain. Kimura disease is distinguished from other conditions, including angiolymphoid hyperplasia, by histopathological features including follicular hyperplasia, reactive germinal centers, abundant eosinophilia, eosinophilic microabscesses, preserved nodal architecture, Warthin-Finkeldy polykaryocytes, and capsular fibrosis. Herein, we describe the clinical presentation, pathology, and diagnosis of a single case of a 39-year-old treated at an academic center in Texas.
