Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease) after laparoscopic Roux-en-Y gastric bypass for morbid obesity: A case report

Abstract

Introduction. Kikuchi-Fujimoto disease, or histiocytic necrotizing lymphadenitis, is a rare, benign, autoimmune condition characterized by lymphadenopathy, fever and neutropenia. It is a self-limited condition of unknown etiology. Case presentation. We report the case of a 45-year-old Caucasian man with the first known case of Kikuchi disease associated with dramatic weight loss after bariatric surgery. Conclusion: Although the association between Kikuchi disease and bariatric surgery may be entirely coincidental, we speculate whether the immune dysfunction associated with weight loss may have played an etiologic role in this process. © 2012 Garcia-Arnes et al.; licensee BioMed Central Ltd.
