Kikuchi-Fujimoto's disease involving mesenteric nodes: a report and review of literature.

An adolescent boy underwent laparoscopic evaluation with persisting fever associated with colicky abdominal pain of about 3 weeks duration after a CT study of his abdomen revealed mesenteric adenopathy. Histopathological evaluation of the excised mesenteric nodes showed features of histiocytic necrotising lymphadenopathy suggestive of Kikuchi-Fujimoto lymphadenopathy which was confirmed on immunehistochemistry staining. Kikuchi-Fujimoto's disease involving the mesenteric nodes is extremely unusual and can be confounding with a mistaken diagnosis of and prolonged treatment for tuberculosis. The authors present a case of Kikuchi-Fujimoto's disease involving the mesenteric lymph nodes and discuss the various aspects of diagnosis and management of the case along with a review of published literature.
