Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease) after laparoscopic Roux-en-Y gastric bypass for morbid obesity: a case report. J Med Case Rep. 2012; 6(1):340http://hdl.handle.net/10668/1488Case reportIntroduction 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.enLinfadenitis Necrotizante HistiocíticaEnfermedades LinfáticasDerivación GástricaCirugía BariátricaMedical Subject Headings::Named Groups::Persons::MenMedical Subject Headings::Named Groups::Persons::Age Groups::AdultMedical Subject Headings::Diseases::Hemic and Lymphatic Diseases::Lymphatic Diseases::Lymphadenitis::Histiocytic Necrotizing LymphadenitisMedical Subject Headings::Diseases::Hemic and Lymphatic Diseases::Hematologic Diseases::Leukocyte Disorders::Leukopenia::Agranulocytosis::NeutropeniaMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Surgical Procedures, Operative::Bariatric Surgery::Gastric Bypassresearch article23043774open access10.1186/1752-1947-6-3401752-1947PMC3492049
